Ausrichtung der Geschäftspolitik am Konzerninteresse? – Regelungsvorschläge für ein europäisches Konzernrecht
Creators: name: Krapp, Hannah
Publisher: name: Studentische Zeitschrift für Rechtswissenschaft Heidelberg – Wissenschaft Online
Year: 2019

description: Die Diskussion über eine europäische Konzernrechtsregelung hat zuletzt wieder Fahrt aufgenommen. Vorrangiges Ziel des neuen Regelungsansatzes ist die europaweit einheitliche Anerkennung des – über das Interesse der Einzelgesellschaft im Konzern hinausgehenden – Gruppeninteresses. Dies soll europaweit tätigen Unternehmensgruppen eine rechtssichere und effiziente Gruppenführung über die Binnenmarktgrenzen hinweg ermöglichen. Aufgrund vielfältiger Unsicherheiten und Hemmnisse, die sich für grenzüberschreitende Unternehmensgruppen ergeben, ist eine solche Regelung auch notwendig. Fraglich ist, wie die Anerkennung des Gruppeninteresses konkret in einem europäischen Rechtsakt umgesetzt werden könnte. Es existieren verschiedene Vorschläge und Konzepte, die es sich näher zu betrachten lohnt. After quite a long period of silence, the discussion about a European legal act on corporate groups has come back to life in the past few years. The main objective of the new approach is to recognize the interest of the group uniformly all over the EU. This recognition is intended to provide a possibility of efficient group governance throughout the European internal market. Because of the many different company law systems in the EU and the associated uncertainties and impediments regarding international group governance such an act is very much needed. There are already several proposals and concepts for the implementation of the recognition of the group interest in a European legislative act which are worth being examined in greater detail.

description: Context With the more frequent use of cross sectional imaging, the detection of cystic pancreatic incidentalomas has become a relatively common entity. The commonest cystic incidentalomas are neoplastic. Pseudocysts are the most single common pathological entity. Foregut cystic lesions as a pathological entity are rare but mostly observed in the mediastinum. Ciliated foregut cysts of the pancreas are very rare and an extremely uncommon cause of a cystic lesion within the pancreas. Case report We present herewith an uncommon case of a large cystic lesion, confirmed as a ciliated foregut cyst on final histology arising from the body and tail of the pancreas. The lesion was very effectively treated with a laparoscopic distal pancreatectomy and splenectomy. Conclusion The rarity of the lesion makes the case worth reporting.

description: Tracy and Widom showed that fundamentally important kernels in random matrix theory arise from differential equations with rational coefficients. More generally, this paper considers symmetric Hamiltonian systems abd determines the properties of kernels that arise from them. The inverse spectral problem for self-adjoint Hankel operators gives a sufficient condition for a self-adjoint operator to be the Hankel operator on $L^2(0, \infty)$ from a linear system in continuous time; thus this paper expresses certain kernels as squares of Hankel operators. For a suitable linear system $(-A,B,C)$ with one dimensional input and output spaces, there exists a Hankel operator $Γ$ with kernel $ϕ_{(x)}(s+t)=Ce^{-(2x+s+t)A}B$ such that $\det (I+(z-1)ΓΓ^\dagger)$ is the generating function of a determinantal random point field.

description: Context Pancreatic desmoplastic small round cell tumour (DSRCT) is an extremely rare malignancy of which very few reports exist. It follows an aggressive course and has a dismal prognosis. Case report A twenty-four-year-old male presented with a one-month history of rapidly progressive obstructive jaundice associated with abdominal pain suggestive of a biliary colic. Contrast-enhanced CT (CECT) of the abdomen revealed a pancreatic head mass. He underwent a pancreaticoduodenectomy and adjuvant chemotherapy and is disease free one year after surgery. Conclusion This is the first reported case of a pancreatic head DSRCT, discovered in a young male investigated for a short history of painful obstructive jaundice.

description: Context Pancreatic neuroendocrine tumor (P-NET) is a rare and slow-growing tumor. Unfortunately, there is no clear consensus on the role and timing of surgery for primary tumor and liver metastases, although current reports refer to liver surgery including LT for unresectable liver metastases. Case report A thirty-nine-year-old man was diagnosed with nonfunctioning pancreatic neuroendocrine tumor (P-NET) in the pancreatic head, with multiple liver metastases. The tumor was 2.5 cm in diameter and he was asymptomatic. Small but multiple metastases were detected in the liver, and no extrahepatic metastases were observed. We initially intended to control the liver metastases before resection of the primary tumor. To begin with, transarterial chemoembolization (TACE) and transcatheter arterial infusion (TAI) were repeated. Thereafter, systemic chemotherapy and biotherapy were introduced according to follow-up assessments. Unfortunately, imaging assessment at about 10 months later revealed that liver metastases were partially enlarged, although some were successfully treated. Therefore, these therapies were switched to other regimens, and TACE/TAI, systemic chemotherapies and biotherapies were repeated. Although liver metastases seemed to be stable for a while, the primary tumor was enlarged even after therapy. At 3.5 years after initial diagnosis, the primary tumor became symptomatic (pain and jaundice). Liver metastases enlarged and massive swelling of the para-aortic lymph nodes was observed. Thereafter, palliative therapy was the main course of action. He died at 4.3 years after initial diagnosis. Conclusion Our young patient could have been a candidate for initial surgery for primary tumor and might have had a chance of subsequent liver transplantation for unresectable metastases. Surgeons still face questions in deciding the best surgical scenario in patients with P-NET with liver metastases.

description: Painleve's transcendental differential equation P_{VI} may be expressed as the consistency condition for a pair of linear differential equations with 2 by 2 matrix coefficients with rational entries. By a construction due to Tracy and Widom, this linear system is associated with certain kernels which give trace class operators on Hilbert space. This paper expresses such operators in terms of the Hankel operators Γ_ϕof linear systems which are realised in terms of the Laurent coefficients of the solutions of the differential equations. Let P_{(t infty)}:L^2(0, \infty)\to L^2(t, \infty) be the orthogonal projection. For such, the Fredholm determinant τ(t)=det (I-P_{(t, \infty)}Γ_ϕ) defines the tau function, which is here expressed in terms of the solutions of a matrix Gelfand--Levitan equation. For suitable paramters, solutions of the hypergeometric equation give a linear system with similar properties. For meromorphic transfer functions \hatϕthat have poles on an arithmetic progression, the corresponding Hankel operator has a simple form with respect to an exponential basis in L^2(0, \infty); so τ(t) can be expressed in terms of finite determinants. This applies to elliptic functions of the second kind, such as satisfy Lame's equation with \ell=1.

description: The periodic KdV equation u_t=u_{xxx}+βuu_x arises from a Hamiltonian system with infinite-dimensional phase space L^2(T). Bourgain has shown that there exists a Gibbs measure νon balls \{ϕ:\VertΦ\Vert^2_{L^2}\leq N\} in the phase space such that the Cauchy problem for KdV is well posed on the support of ν, and νis invariant under the KdV flow. This paper shows that νsatisfies a logarithmic Sobolev inequality. The stationary points of the Hamiltonian on spheres are found in terms of elliptic functions, and they are shown to be linearly stable. The paper also presents logarithmic Sobolev inequalities for the modified periodic KdV equation and the cubic nonlinear Schrödinger equation, for small values of N.

description: Pancreatitis is notorious to cause vascular complications. While arterial complications include pseudoaneurysm formation with a propensity to bleed, venous complications can be quite myriad. Venous involvement in pancreatitis often presents with thrombosis. From time to time case reports and series of unusual venous complications associated with pancreatitis have, however, been described. In this article, we review multitudinous venous complications in the setting of pancreatitis and propose a system to classify pancreatitis associated venous complications.

description: Pancreatic cancer is the fourth leading cause of cancer-related death in the United States and one of the leading causes of cancer mortality in the United States. Due to its aggressive behavior and lack of effective therapies, palliation plays a critical role in the management of the disease. Most patients with pancreatic cancer suffer from severe pain, which adversely predicts prognosis and significantly impacts the quality of life. Therefore pain management plays a central role in palliation. Non-steroidal anti-inflammatory drugs and opioid agents are often first line medications in pain management, but they do not target the underlying pathophysiology of pain and their use is limited by adverse effects and dependence. The proposed mechanisms of pain development in pancreatic cancer include neurogenic inflammation and ductal hypertension which may be targeted by endoscopic therapies. Endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) and pancreatic duct stent placement are the two primary endoscopic modalities for palliative management in pancreatic cancer patients with refractory pain.  Other endoscopic treatments such as biliary stent placement and enteral stent placement for biliary and duodenal obstruction may also help palliate pain in addition to their role in decompression. This article reviews the existing evidence for these endoscopic interventions for pain management in pancreatic cancer.

description: Let v be a real polynomial of even degree, and let ρbe the equilibrium probability measure for v with support S; so that v(x)\geq 2\int \log |x-y| ρ(dy)+C_v for some constant C_v with support S. Then S is the union of finitely many bounded intervals with endpoints delta_j, and ρis given by an algebrais weight w(x) on S. The system of orthogonal polynomials for w gives rise to the Magnus--Schlesinger differential equations. This paper identifies the tau function of this system with the Hankel determinant det[\in x^{j+k}ρ(dx)] of ρ. The solutions of the Magnus--Schlesinger equations are realised by a linear system, which is used to compute the tau function in terms of a Gelfand--Levitan equaiton. The tau function is associated with a potential q and a scattering problem for the Schrodinger operator with potential q. For some algebro-geometric potentials, the paper solves the scattering problem in terms of linear systems. The theory extends naturally to elliptic curves and resolves the case where S has exactly two intervals.

description: The geometric and algebraic properties of Gray categories with duals are investigated by means of a diagrammatic calculus. The diagrams are three-dimensional stratifications of a cube, with regions, surfaces, lines and vertices labelled by Gray category data. These can be viewed as a generalisation of ribbon diagrams. The Gray categories present two types of duals, which are extended to functors of strict tricategories with natural isomorphisms, and correspond directly to symmetries of the diagrams. It is shown that these functors can be strictified so that the symmetries of a cube are realised exactly. A new condition on Gray categories with duals called the spatial condition is defined. A class of diagrams for which the evaluation for spatial Gray categories is invariant under homeomorphisms is exhibited. This relation between the geometry of the diagrams and structures in the Gray categories proves useful in computations and has potential applications in topological quantum field theory.

description: Context Before the initiation of cytotoxic therapy for locally unresectable pancreatic cancer, staging laparoscopy is an important diagnostic method for both the detection of occult small lesions and the extraction of a tumor sample for advanced pathological examination using core needle biopsy (CNB) under laparoscopic ultrasonography (LUS) guidance. Objective This study aimed to evaluate the safety and usefulness of LUS-guided CNB in pancreatic cancer. Methods Consecutive patients with locally unresectable pancreatic cancer who underwent staging laparoscopy were retrospectively analyzed. LUS-guided CNB was performed percutaneously under a laparoscopic view. The clinical results of the LUS-guided CNB group and the non-LUS-guided CNB group were compared. Results Forty-eight patients who underwent staging laparoscopy by LUS-guided CNB or endoscopic ultrasound-guided fine needle aspiration were identified. LUS-guided CNB was performed in 25 patients. The mean tumor size in the LUS-guided CNB group was significantly larger than that in the non-LUS-guided CNB group. No significant difference was observed between the two groups in operating time or bleeding volume. The rates of malignancy diagnosis and histological classification subtyping were significantly higher in the LUS-guided CNB group. Histologically differentiated adenocarcinoma was identified in 15 patients using samples acquired by LUS-guided CNB. There was no uncontrollable bleeding or other complications, and a significant difference in the occurrence of peritoneal dissemination after laparoscopic examination was observed between the two groups. Conclusion LUS-guided CNB enables the safe acquisition of sufficient tissue volumes for certain pathological analyses required to determine treatment strategies for locally unresectable advanced pancreatic cancer.

description: Chronic pancreatitis is a challenging disease; the constellation of chronic abdominal pain and metabolic derangements present unique difficulties to the treating physician. Initial treatment revolves around lifestyle modification, pain control, and management of exocrine insufficiency. In refractory cases, total pancreatectomy with islet cell auto transplantation (TP-IAT) is an option for patients with diffuse disease not amenable to subtotal pancreatectomy or a decompressive (drainage) operation. This procedure aspires to alleviate pain and avoid surgically induced brittle diabetes, a morbid complication of total pancreatectomy alone. Herein, we review the indications, optimal timing, surgical outcomes and controversies for TP-IAT, focusing on recently published reports.

This is applicable whether the method of assessing QCD is fixed order calculation, resummation, or parton showers. In this talk we discuss tools for tackling the problem of performing exact color summed calculations. We start with theoretical tools in the form of the (standard) trace bases and the orthogonal multiplet bases (for which a general method of construction was recently presented). Following this, we focus on two new packages for performing color structure calculations: one easy to use Mathematica package, ColorMath, and one C++ package, ColorFull, which is suitable for more demanding calculations, and for interfacing with event generators.

description: This paper concerns Gibbs measures $ν$ for some nonlinear PDE over the $D$-torus ${\bf T}^D$. The Hamiltonian $H=\int_{{\bf T}^D} \Vert\nabla u\Vert^2 - \int_{{\bf T}^D} \vert u\vert^p$ has canonical equations with solutions in $Ω_N=\{ u\in L^2({\bf T}^D) :\int \vert u\vert^2\leq N\}$. For $D=1$ and $2\leq p<6$, $Ω_N$ supports the Gibbs measure $ν(du)=Z^{-1}e^{-H(u)}\prod_{x\in {\bf T}} du(x)$ which is normalized and formally invariant under the flow generated by the PDE. The paper proves that $(Ω_N, \Vert\cdot\Vert_{L^2}, ν)$ is a metric probability space of finite diameter that satisfies the logarithmic Sobolev inequalities for the periodic $KdV$, the focussing cubic nonlinear Schrödinger equation and the periodic Zakharov system. For suitable subset of $Ω_N$, a logarithmic Sobolev inequality also holds in the critical case $p=6$. For $D=2$, the Gross--Piatevskii equation has $H=\int_{{\bf T}^2} \Vert\nabla u\Vert^2-\int_{{\bf T}^2} (V\ast \vert u\vert^2 ) \vert u\vert^2$, for a suitable bounded interaction potential $V$ and the Gibbs measure $ν$ lies on a metric probability space $(Ω, \Vert\cdot\Vert_{H^{-s}}, ν)$ which satisfies $LSI$. In the above cases, $(Ω, d, ν)$ is the limit in $L^2$ transportation distance of finite-dimensional $(Ω_n, \Vert \cdot \Vert,ν_n)$ given by Fourier sums.

description: Glucocorticoids (GC) are renowned for their pleiotropic effects in all organ systems, their ubiquitous use in numerous clinical settings, and the abundant adverse effects they may exert, particularly in the endocrine-metabolic sphere. Although hyperglycemia and insulin resistance are well-defined GC-induced diabetogenic phenomena, an added component of direct injury to pancreatic β cells (PBC) may also participate in this scenario. Indeed, the apoptotic capacity of GC is widely recognized, and PBC do not escape this situation. No unified pathway has been characterized regarding GC-induced cell death; instead, it appears to depend on the specific machinery of each cell type, determining a great heterogeneity in GC-dependent apoptotic mechanisms among different tissues. In PBC, GC can induce the expression or activation of pro-apoptotic proteins (Bax, BAD, p38), repress anti-apoptotic proteins (Bcl-2), deactivate pro-survival mechanisms (cAMP-PKA signaling) and sensitize the cell to death induced by oxidative stress, fatty acids, hyperglycemia and cytokines. Although proliferative pathways (TGF-β, H-ras) are activated simultaneously – and an increase in PBC mass may be observed initially – pro-apoptotic and anti-proliferative mechanisms appear to eventually overcome their pro-survival counterparts, due to their synergic and aggregative action. Key molecules such as p38 and the cAMP-PKA system may be promising therapeutic targets in the prevention of GC-induced cell death.

description: Pancreatic ductal adenocarcinoma (PDAC) is the fourth most common cause of death from cancer. Its 5-year survival rate is less than 5%. This poor prognosis is mostly due to the cancer’s early invasion and metastasis formation, leading to an initial diagnosis at an advanced incurable stage in the majority of patients. The only potentially curative treatment is radical surgical resection. The effect of current chemotherapeutics or radiotherapy is limited. Novel therapeutic strategies are therefore much needed. One of the hallmarks of PDAC is its abundant desmoplastic (stromal) reaction. The Hedgehog (Hh) signaling pathway is critical for embryologic development of the pancreas. Aberrant Hh signaling promotes pancreatic carcinogenesis, the maintenance of the tumor microenvironment and stromal growth. The canonical Hh-pathway in the tumor stroma has been targeted widely but has not yet lead to hopeful clinical results. Targeting both the tumor and its surrounding stroma through Hh pathway inhibition by also targeting non-canonical pathways as apparent in the tumor cell may therefore be a novel treatment strategy for PDAC.

description: The relations in the tautological ring of the moduli space M_g of nonsingular curves conjectured by Faber-Zagier in 2000 and extended to the moduli space of stable pointed curves by Pixton in 2012 are based upon two hypergeometric series A and B. The question of the geometric origins of these series has been solved in at least two ways (via the Frobenius structures associated to 3-spin curves and to CP1). The series A and B also appear in the study of descendent integration on the moduli spaces of open and closed curves. We survey here the various occurrences of A and B starting from their appearance in the asymptotic expansion of the Airy function (calculated by Stokes in the 19th century). Several open questions are proposed.

description: Context Treatment of pancreatic fistulae after pancreaticoduodenectomy is extremely important because it determines the patient's postoperative course. In particular, treatment of grade B cases should be conducted in a timely manner to avoid deterioration to grade C. Objective We report the successful treatment of six cases of postoperative intractable, grade B pancreatic fistulae, in which fistula closure was achieved through the use of tissue adhesive. Methods Six subjects presented at our hospital with grade B pancreatic fistulae after pancreaticoduodenectomy. In all cases, the drain amylase values were high immediately after the operation, and the replacement of the drain was enforced. Closure of the fistula was performed by pouring tissue adhesive into the fistula from the drain, after the fistula had been straightened. Results Closure of the fistula was achieved in all six cases at the first attempt. The average fistula length was 13.2 cm, the average volume of pancreatic fluid discharge just before treatment was 63.3 mL, the average amylase value in the drainage was 40,338.5 IU/L, and the subjects were discharged from hospital an average of 8.8 days after treatment. There were no recurrences after treatment. Conclusion Intractable pancreatic fistulae can be effectively treated using the tissue adhesive method.

description: Solar flares are characterized by sudden bursts of electromagnetic radiation from the Sun's surface, and caused by the changes in magnetic field states in solar active regions. Earth and its surrounding space environment can suffer from various negative impacts caused by solar flares ranging from electronic communication disruption to radiation exposure-based health risks to the astronauts. In this paper, we address the solar flare prediction problem from magnetic field parameter-based multivariate time series (MVTS) data using multiple state-of-the-art machine learning classifiers that include MINImally RandOm Convolutional KErnel Transform (MINIROCKET), Support Vector Machine (SVM), Canonical Interval Forest (CIF), Multiple Representations SEQuence Learner (MR-SEQL), Long Short-Term Memory (LSTM)-based deep learning model, and the Transformer model. We showed our results on the Space Weather ANalytics for Solar Flares (SWAN-SF) benchmark data set, a partitioned collection of MVTS data of active region magnetic field parameters spanning over 9 years of operation of the Solar Dynamics Observatory (SDO). The MVTS instances of the SWAN-SF dataset are labeled by GOES X-ray flux-based flare class labels, and attributed to extreme class imbalance because of the rarity of the major flaring events (e.g., X and M). To minimize the dimensionality of the data, we also included data preprocessing activities such as statistical summarization. We used the true skill statistic (TSS) and realizations of the Heidke Skill Score (HSS; HSS2) score as a performance validation metric in this class-imbalanced dataset. Finally, we demonstrate the advantages of the MVTS learning algorithm MINIROCKET, which produces better results than other classifiers without the need for essential data preprocessing steps such as normalization, statistical summarization, and class imbalance handling heuristics.

description: Mound 2 was excavated by Basil Brown in 1938, the year before his famous discovery of the ship burial in Mound 1. It was re-investigated in the 1980s and 90s by Martin Carver, who concluded it was originally a rich chamber burial covered by a boat and then buried in the mound. Carver's team reconstructed the mound to something like its original height and profile, the only mound in the royal graveyard for which this has been done.

description: This article considers Whittaker's function $W_{κ,μ}$ where $κ$ is real and $μ$ is real or purely imaginary. Then $φ(x)=x^{-μ-1/2}W_{κ,μ}(x)$ arises as the scattering function of a continuous time linear system with state space $L^2(1/2, \infty )$ and input and output spaces ${\bf C}$. The Hankel operator $Γ_φ$ on $L^2(0, \infty )$ is expressed as a matrix with respect to the Laguerre basis and gives the Hankel matrix of moments of a Jacobi weight $w$. The operation of translating $φ$ is equivalent to multiplying $w$ by an exponential factor to give $w_\varepsilon$. The determinant of the Hankel matrix of moments of $w_\varepsilon$ satisfies the $σ$ form of Painlevé's transcendental differential equation $PV$. It is shown that $Γ_φ$ gives rise to the Whittaker kernel from random matrix theory, as studied by Borodin and Olshanski (Comm. Math. Phys. 211 (2000), 335--358).\par

description: Objective Our aim was to investigate the relationship between imbalances of plasma amino acids and pain in chronic pancreatitis (CP). Methods Thirty patients with alcoholic CP in an exocrine-insufficient state were examined. We divided them between diet and control group. Diet group ingested 80g/300kcal of the elemental diet "Elental®". This diet of 300 kcal/day was administered for two months. Selected clinical and laboratory values were compared between both groups before and after diet. Pain was observed and compared using a visual analog scale (VAS). Results There was no significant difference in the BMI between both groups before and after diet. The serum albumin level in diet group after diet was significantly higher than in control group (P=0.036). There was no significant difference in HbA1c between both groups before and after diet. The total amino acid concentration was significantly higher in diet group after diet than in control group (P=0.033). The concentrations of serum histidine and methionine in diet group after diet were significantly higher than in control group (histidine, P=0.022; methionine, P=0.026). The concentration of serum glutamate in diet group after diet was significantly lower than in control group (P=0.027). The balance of amino acids in diet group was normalized after the Elental® was ingested. The VAS score was significantly lower in diet group after diet than in control group (P=0.018). Conclusion These amino acid levels and pancreatic pain were improved by the elemental diet. The pancreatic pain may be related to these amino acid imbalances.

description: Context Due to maldigestion, pancreatic exocrine insufficiency (PEI) in chronic pancreatitis may lead to deficiencies in fat-soluble vitamins, including vitamin D. This may, in turn, can cause disturbances in bone metabolism and reduce bone mineral density. Objective To conduct a prospective study of maldigestion, bone metabolism, and bone mineral density in a group of patients with chronic pancreatitis. Methods A total of 50 male patients with proven chronic pancreatitis (36/50 alcohol; 42/50 smokers) were studied. Pancreatic exocrine function was assessed using the fecal elastase-1 test. Blood and urine samples were analyzed for parameters related to pancreatitis, nutrition, endocrine status, and bone metabolism. Bone mineral density was measured with dual-energy X-ray absorption (DXA) and conventional vertebral X-rays. A standardized questionnaire for osteoporosis was given. Results Twenty-eight of the patients had PEI (fecal elastase-1 <200 µg/g), 25 had bone pain, and 21 had a history of bone fractures. Serum 25-OH-cholecalciferol and urine calcium were decreased and deoxypyridinoline concentrations were increased in urine. Serum calcium, bone-specific alkaline phosphatase, and parathyroid hormone were within normal limits. There was no statistical correlation between three classes of fecal elastase-1 (<100 µg/g; 100-200 µg/g; >200 µg/g) and calcium, 25-OH-cholecalciferol, or deoxypyridinoline. Of the 15 patients who underwent DXA, 5 had normal bone mineral density (T score >-1), 9 had osteopenia (T score from -1 to – 2.5), and 1 had osteoporosis (T score

description: Context Cystic neoplasms, which are less common forms of exocrine pancreatic neoplasms, consist of mainly intraductal papillary mucinous neoplasms (IPMN) and mucinous cystic neoplasms. Mucinous cystic neoplasms, unlike IPMN, are not associated with ductal growth, are usually multilocular in nature, and have ovarian type stroma. Mucinous cystadenocarcinoma is a type of mucinous cystic neoplasm more commonly found in women. Intraductal oncocytic papillary neoplasms of the pancreas are the least common variant of IPMN. Despite this classification, intraductal oncocytic papillary neoplasms have been compared to mucinous cystic neoplasms in previous studies and the classification is still questioned. Case report We report a rare case of an intraductal oncocytic papillary neoplasm of the pancreas occurring in a 52-year-old male with a prior history of surgically excised mucinous cystadenocarcinoma. This is the first known case of an intraductal oncocytic papillary neoplasm occurring after a prior pancreatic neoplasm. Conclusions As the diagnosis of intraductal oncocytic papillary neoplasms are rare, having only a few case reports and small series on which to understand its disease process, it is imperative to discuss each case and detail possible correlations with other pancreatic cystic neoplasms as well as distinctions from its current association within IPMN.
