Primary Pure Squamous Cell Carcinoma of the Gallbladder Locally Invading the Liver, Duodenum, and Stomach: A Case Report and Literature Review
Authors: Aldrin C Alpuerto, Maximo E Mora, R Jonathan Robitsek, Sebastian D Schubl
Journal: Case Rep Surg (2017)
MeSH terms: Case Reports

Primary pure squamous cell carcinoma (SCC) of the gallbladder is an exceptionally rare type of tumor that comprises only 1% of all gallbladder cancer. SCC of the gallbladder portends a worse prognosis than the more common adenocarcinoma variant because of its aggressive invasion to local structures and because it is often diagnosed at an advanced stage. Owing to its rarity, diagnosis and management can be challenging. Herein, we present the case of a 75-year-old female complaining of abdominal pain, nausea, and vomiting. Computed tomography and ultrasonography results of the abdomen were consistent with acute cholecystitis and cholelithiasis. Histologic evaluation of the resected mass revealed a malignant tumor with prominent keratinization, confirming the diagnosis of an invasive primary pure SCC of the gallbladder. Microscopic examination showed direct infiltration to the liver, duodenum, and stomach. This case report describes the hospital course of a patient with SCC of the gallbladder and suggests that gallbladder cancer should be considered as part of the differential diagnosis in elderly patients presenting with acute cholecystitis. In addition, this article will review existing literature to examine the utility of different diagnostic techniques and treatment modalities available in the management of gallbladder cancer.
A Rare Case of Tumoral Calcium Pyrophosphate Dihydrate Crystal Deposition Disease of the Wrist Joint
Authors: Osamu Nakamura, Yoshio Kaji, Yoshiki Yamagami, Kounosuke Yamaguchi, Hideki Nishimura, Natsuko Fukuoka, Tetsuji Yamamoto
Journal: Case Rep Orthop (2015)

Introduction. Tumoral calcium pyrophosphate dihydrate (CPPD) crystal deposition disease (CPPDCD), also known as tophaceous calcium pyrophosphate deposition disease (CPDD), is a tumorlike lesion, and it should be distinguished from usual CPDD that causes severe joint inflammation and arthralgia. A case of tumoral CPPDCD of the wrist joint that required differentiation from synovial osteochondromatosis is described. Case Presentation. The patient was a 78-year-old woman with a 5-year history of nodular lesions at the right wrist that had gradually increased in size. An excisional biopsy and a histological examination of the excised nodular lesions by hematoxylin and eosin (H&E) staining were performed, demonstrating numerous polarizable, rhabdoid, and rectangular crystals, surrounded by fibroblasts, macrophages, and foreign body-type giant cells, consistent with tumoral CPPDCD. Conclusion. Tumoral CPPDCD, especially at the wrist joint, is rare, and, to the best of our knowledge, only 2 articles have been published. This case seems to need further follow-up for recurrence, because tumoral CPPDCD may recur after complete or incomplete surgical excision.
Diverse presentation of secondary aortoenteric fistulae
Authors: Tracey Simon, Edward Feller
Journal: Case Rep Med (2011)
MeSH terms: Case Reports

Secondary aortoenteric fistula, due to mechanical erosion or infection of a prosthetic graft, is a very rare cause of gastrointestinal bleeding and an uncommon complication of abdominal aortic aneurysm repair. A retrospective chart review conducted at our institution revealed 5 cases of secondary AEF occurring between 2006 and 2010. Presentations were diverse, including hematemesis, coffee-ground emesis, and unexplained sepsis. Delay in diagnosis was common. In reporting these cases, we seek to highlight the diverse clinical spectrum and potentially misleading features of this condition. Clinicians must retain a high index of suspicion to avoid potentially catastrophic outcomes.
A Rare Case of Nonsecretory Multiple Myeloma in Lagos, Nigeria: A Case Report and Literature Review
Authors: Ebele Uche, Akinsegun Akinbami, Sarah John-Olabode, Adedoyin Dosunmu, Majeed Odesanya
Journal: Case Rep Med (2015)

Multiple myeloma (MM) is a plasma cell disorder associated with clonal proliferation of plasma cells. Nonsecretory multiple myeloma (NSMM) is a rare variant of MM and accounts for approximately 1% to 5% of all cases. It is defined as symptomatic myeloma without detectable monoclonal immunoglobulin on serum or urine electrophoresis. This variant usually poses a diagnostic challenge to the clinician. We present a 60-year-old Nigerian man who was investigated extensively for bone pain, weight loss, and anaemia. He was eventually diagnosed as having nonsecretory multiple myeloma based on histology and immunohistochemistry results of bone marrow trephine biopsy. He is currently being managed with bortezomib, doxorubicin, and thalidomide, as well as zoledronic acid. He is also on anticoagulation. He continues to show remarkable clinical improvement. We describe this case report and literature review for better awareness amongst medical practitioners and pathologists.
Arterial emboli complicating Cisplatin therapy
Authors: Campbell D Tait, Elaine M Rankin
Journal: Case Rep Oncol Med (2012)
MeSH terms: Case Reports

We report three cases of arterial emboli in patients with lung cancer treated with cisplatin chemotherapy. All three patients were managed without surgical intervention but subsequent oncological treatment was complicated by the sequelae of arterial emboli. We discuss the issues surrounding these patients and the importance of identifying patients at risk of arterial embolic phenomena with cisplatin treatment.
Case Report: Unexpected Remission From Extreme and Enduring Bulimia Nervosa With Repeated Ketamine Assisted Psychotherapy
Authors: Anya Ragnhildstveit, Laura Kate Jackson, Sarah Cunningham, Linda Good, Quinn Tanner, Matthew Roughan, Patricia Henrie-Barrus
Journal: Front Psychiatry (2021)
Keywords: binge-eating, bulimia nervosa, case report, eating disorder, ketamine, ketamine assisted psychotherapy, psychopharmacology, purging
MeSH terms: Case Reports

Background: Bulimia nervosa is a disabling psychiatric disorder that considerably impairs physical health, disrupts psychosocial functioning, and reduces overall quality of life. Despite available treatment, less than half of sufferers achieve recovery and approximately a third become chronically ill. Extreme and enduring cases are particularly resistant to first-line treatment, namely antidepressants and cognitive behavioral therapy, and have the highest rate of premature mortality. Here, we demonstrate that in such cases, repeated sessions of ketamine assisted psychotherapy (KAP) is an effective treatment alternative for improving symptoms. Case Presentation: A 21-year-old woman presented with extreme and enduring bulimia nervosa. She reported recurrent binge-eating and purging by self-induced vomiting 40 episodes per day, which proved refractory to both pharmacological and behavioral treatment at the outpatient, residential, and inpatient level. Provided this, her physician recommended repeated KAP as an exploratory and off-label intervention for her eating disorder. The patient underwent three courses of KAP over 3 months, with each course consisting of six sessions scheduled twice weekly. She showed dramatic reductions in binge-eating and purging following the first course of treatment that continued with the second and third. Complete cessation of behavioral symptoms was achieved 3 months post-treatment. Her remission has sustained for over 1 year to date. Conclusions: To our knowledge, this is the first report of repeated KAP used to treat bulimia nervosa that led to complete and sustained remission, a rare outcome for severe and enduring cases, let alone extreme ones. Additionally, it highlights the degree to which KAP can be tailored at the individual level based on symptom severity and treatment response. While its mechanism of action is unclear, repeated KAP is a promising intervention for bulimia nervosa that warrants future research and clinical practice consideration.
Vertebral Artery Fenestration
Authors: Alp Ozpinar, Stephen T Magill, Jason M Davies, Michael W McDermott
Journal: Cureus (2015)
Keywords: anatomy, fenestration, vascular, vertebral artery
MeSH terms: Case Reports

Fenestration of the vertebral artery is a rare vascular anomaly that has been observed at autopsy and on angiography. It is most commonly seen in the extracranial segments of the vertebral artery. This congenital anomaly can arise during multiple different stages of embryological development of the vertebral artery. The clinical significance is unclear, but multiple studies have reported association with other vascular anomalies. Awareness of vascular anomalies is crucial to avoid iatrogenic injuries during endovascular diagnostic and therapeutic interventions. Here, we present a case of a patient with an intracranial vertebral artery fenestration that was identified during work-up for a foramen magnum mass.
Fine needle aspiration diagnosis of extracranial glioblastoma multiforme: Case report and review of the literature
Authors: Stacey Schultz, Gregory S Pinsky, Nancy C Wu, Marc C Chamberlain, A Sonali Rodrigo, Sue E Martin
Journal: Cytojournal (2005)

Background:
Hitherto uncommon, the incidence of extracranial metastases of primary brain malignancies may increase, with improved treatment methods and longer patient survival. Fine needle aspiration biopsy is a simple, safe and reliable method to diagnose metastatic malignancy. It has definite advantages over tissue biopsy, which is more invasive and is of higher risk to the patient. Ours is a case of glioblastoma multiforme, which metastasized to the scalp and was diagnosed on fine needle aspiration biopsy. Only a few articles document the cytological features of extracranial glioblastoma multiforme, diagnosed by fine needle aspiration biopsy.
Case presentation:
We report the case of an elderly female who presented with focal neurological symptoms. She was diagnosed radiologically with an intracranial lesion in the left temporal region, which was subsequently resected. Histology revealed a glioblastoma multiforme confirmed by immunohistochemistry. The tumor recurred subsequently and the patient was treated with chemotherapy, intraoperatively. At a later stage, she presented with a scalp mass on which fine needle aspiration biopsy was performed. The cytomorphological features aided by immunohistochemistry supported a diagnosis of metastatic glioblastoma multiforme. The mass was later resected and histology confirmed the fine needle aspiration diagnosis of glioblastoma multiforme.
Conclusion:
Reports of extracranial metastases of primary brain tumors are few. When they do occur, the primary cause is implantation during surgery or biopsy. However, spontaneous metastases to other organs do occur rarely. We believe fine needle aspiration biopsy to be very useful in the diagnosis of metastatic glioblastoma multiforme. The ability to use a cellblock for immunohistochemical studies is greatly advantageous and helpful in differentiating this tumor, from other malignancies that can occur in the scalp. A detailed discussion of the material obtained from fine needle aspiration biopsy of metastatic glioblastoma multiforme is presented, as well as a review of previous accounts in the literature.
Psychogenic Equinovarus Caused by Dislocation of the Chopart Joint Complex
Authors: Ichiro Tonogai, Koichi Sairyo
Journal: Case Rep Orthop (2018)
MeSH terms: Case Reports

Patients with conversion disorder (CD) present with weakness or unexplained movement disorder that may evolve from inciting psychological events, but presentation with rigid deformity is rare. Only one case of CD presenting as foot deformity with atraumatic rigid psychogenic equinovarus has been reported previously. Here we describe a rare case of psychogenic equinovarus in a physically healthy 10-year-old boy. He had noticed left equinovarus deformity upon waking abruptly but had no history of preceding trauma and no relevant medical history. Computed tomography (CT) images revealed dislocation of the left Chopart joint complex, but clinical examination did not suggest an organic neurologic disorder. On further history taking, he reported that he was under psychological stress because of being required to play baseball against his will. When he was given permission to withdraw from this stressful situation, the equinovarus improved without the need for surgical invention. This report highlights the importance of early and accurate diagnosis of psychogenic equinovarus, so that unnecessary surgery can be avoided. This is the first report of psychogenic equinovarus caused by dislocation of the Chopart joint complex that was confirmed with CT.

Authors: James Satalich, Julie Reznicek, Alexandra Bryson, Prayag Pershad, Nicholas Hooper, Jibanananda Satpathy
Journal: Case Rep Orthop (2022)
MeSH terms: Case Reports

Histoplasma capsulatum is a rarely reported cause of prosthetic joint infections. This current case report is of a patient from Trinidad, with a history of a right total knee replacement (TKR), who underwent a successful two-stage revision due to a Histoplasmosis capsulatum periprosthetic joint infection (PJI). This case report offers a unique treatment plan to successfully treat Histoplasmosis capsulatum periprosthetic joint infections and emphasizes the importance of obtaining an accurate travel history.
Bing and neel syndrome
Authors: S Jennane, K Doghmi, E M Mahtat, N Messaoudi, B Varet, M Mikdame
Journal: Case Rep Hematol (2012)

Introduction. We report the case of a Bing and Neel syndrome revealed by an isolated left ptosis. Case Report. a 57-year-old man was followed up since October 2003 for a typical Waldenström's macroglobulinemia. A first complete remission was obtained with chlorambucil. In August 2004, he relapsed. A second complete remission was obtained with RFC chemotherapy regimen (rituximab, fludarabine, and cyclophosphamide). In October 2009, the patient presented with an isolated left ptosis revealing a Bing and Neel syndrome. The diagnosis was suspected on MRI and confirmed by the detection in the CSF of a monoclonal IgM similar to the one found in the plasma. A quite good partial remission has been obtained after one course of RDHAP (rituximab, dexamethasone, cytarabine, and cisplatin) and 3 courses of RDHOx (rituximab, dexamethasone, cytarabine, and oxaliplatin), in addition to ten intrahectal chemotherapy injections. The treatment was followed by intensification and autologous stem cell transplantation. At D58, the patient died due to a septic shock. Conclusion. BNS is a rare and potentially treatable complication of WM. It should be considered in patients with neurologic symptoms and a history of WM.
Ectrodactyly-Ectodermal Dysplasia Clefting Syndrome: A Case Report of Its Dental Management with 2 Years Follow-Up
Authors: Anamika Bharati, Saumya Navit, Suleman Abbas Khan, Seema Jabeen, Nishi Grover, Meenakshi Upadhyay
Journal: Case Rep Dent (2020)
MeSH terms: Case Reports

Ectrodactyly-ectodermal dysplasia clefting syndrome is a rare genetic disorder characterized by the triad of ectrodactyly-ectodermal dysplasia and facial clefting of lip or palate or both along with some systemic manifestations. Although each defect that comprises the syndrome has been known to occur as a separate entity, the congregation of all three anomalies in a single individual appears to be an extremely rare occurrence, with incidence being approximately 1.5/100 million population. Early diagnosis and management of clinical manifestations associated with ectrodactyly-ectodermal dysplasia clefting syndrome present a unique challenge. We report a case of this rare disorder in an 11-year-old male patient along with its dental management using a multidisciplinary approach.
Ruptured Subcapsular Liver Hematoma: A Rare Complication of HELLP Syndrome
Authors: Pratishtha Singh, Kayle Warren, Victor Collier
Journal: Case Reports Hepatol (2020)
MeSH terms: Case Reports

Subcapsular liver hematoma (SLH) is a rare complication of HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome. We report a previously healthy 16-year-old female presenting with pre-eclampsia requiring emergent C-section, who developed immediate postoperative bleeding and abdominal distention. Abdominal computed tomography angiography (CTA) revealed a large encapsulated liver hematoma with active extravasation. The patient was successfully treated with a multidisciplinary approach with medical and surgical management.
Using a multidisciplinary approach to reveal decision-making capacity within acute care for an individual with aphasia
Authors: Ruth Maxwell, Michelle O'Brien, Deirdre O'Donnell, Lauren Christophers, Thilo Kroll
Journal: SAGE Open Med Case Rep (2021)
Keywords: aphasia, capacity, cognition, communication, decision-making, functional capacity assessment, multidisciplinary team
MeSH terms: Case Reports

Formal assessments of cognition that rely on language may conceal the non-linguistic cognitive function of people with aphasia. This may have detrimental consequences for how people with aphasia are supported to reveal communicative and decision-making competence. This case report demonstrates a multidisciplinary team approach to supporting the health and social care decision-making of people with aphasia. The case is a 67-year-old woman with Wernicke's type aphasia. As the issue of long-term care arose, the speech and language therapist used a supported communication approach with the patient who expressed her wish to go home. A multidisciplinary team functional assessment of capacity was undertaken which involved functional assessments and observations of everyday tasks by allied health, nursing, catering and medical staff. In this way, the patient's decision-making capacity was revealed and she was discharged home. A collaborative multidisciplinary team approach using supported communication and functional capacity assessments may be essential for scaffolding the decision-making capacity of people with aphasia.

MeSH terms: Case Reports

Cholangiocarcinoma is a heterogeneous and target-rich disease with differences in actionable targets. Intrahepatic and extrahepatic types of cholangiocarcinoma differ significantly in clinical presentation and underlying genetic aberrations. Research has shown that extrahepatic cholangiocarcinoma is more likely to be associated with ERBB2 (HER2) genetic aberrations. Various anti-HER2 clinical trials, case reports and other molecular studies show that HER2 is a real target in cholangiocarcinoma; however, anti-HER2 agents are still not approved for routine administration. Here, we show in a metastatic cholangiocarcinoma with ERBB2 amplification identified on liquid biopsy (circulating tumor DNA (ctDNA) testing), a dramatic response to now over 12 months of dual-anti-HER2 therapy. We also summarize the current literature on anti-HER2 therapy for cholangiocarcinoma. This would likely become another treatment option for this target-rich disease.
A Case of Kawasaki Disease Accompanied by Encephalitis and Several Kinds of Arrhythmia during the Acute Phase
Authors: Naomi Nakagawa, Masahiro Kamada, Yukiko Ishiguchi, Yuji Moritoh, Kengo Okamoto, Shinji Itamura
Journal: Case Rep Pediatr (2019)
MeSH terms: Case Reports

Although central nervous system complications occasionally accompany during the acute phase of Kawasaki disease, clinically problematic arrhythmia is quite rare. We report a case accompanied by encephalitis and several kinds of problematic arrhythmia. Following the diagnosis of Taussig-Bing anomaly and coarctation of the aorta, the patient underwent aortic arch reconstruction, an arterial switch operation, and ventricular septal defect closure. No significant arrhythmias were observed. At the age of 5 years, the patient presented with a fever, rash, conjunctival hyperemia, and redness of the lips and fingertips. He was subsequently diagnosed with Kawasaki disease. The patient also presented with disorientation, and electroencephalography revealed overall slow-wave activity, indicating encephalitis. The patient received high-dose immunoglobulin and steroid pulse therapy. Sinus arrest was detected on day 10, and an atrial flutter with a 2 : 1 to 4 : 1 atrioventricular conduction block occurred on day 20. Although cardioversion succeeded in alleviating the atrial flatter, the patient experienced significant sinus arrest. The sinus arrest was alleviated 3 days later. Kawasaki disease-induced vasculitis and the arterial switch operation may both have influenced the sinus node dysfunction. Although sinus node function recovered, the possibility of progression into the sinus node dysfunction in the future should be considered.

Authors: Yumiko Matsusue, Kazuhiko Yamamoto, Nobuhiro Yamakawa, Ikumi Yamamoto, Shinpei Matsuda, Hitoshi Yoshimura, Tetsuji Kawakami, Tadaaki Kirita
Journal: Case Rep Dent (2021)
MeSH terms: Case Reports

Here, we report a case of synovial chondromatosis of the temporomandibular joint (TMJ) with numerous loose bodies. A 56-year-old woman was examined in the oral surgery department for trismus and pain in the left TMJ when opening the mouth. Imaging indicated TMJ synovial chondromatosis, and the patient was referred to our department for further examination. Her facial features were symmetrical, and no occlusal abnormalities were found. The maximum mouth opening was 30 mm, and movement of the left mandibular condyle was restricted and accompanied by pain and joint sounds. Panoramic radiography showed deformation of the left mandibular condyle and radiopaque lesions surrounding it. Computed tomography showed numerous small granules around the left mandibular condyle, some of which were calcified. Magnetic resonance imaging showed anterior disc displacement without reduction in the left TMJ and hypointense lesions on T2-weighted images. Bone scintigraphy showed an accumulation in the area of the left TMJ. Based on the diagnosis of the left TMJ synovial chondromatosis, the lesions were removed, and plastic surgery on the mandibular condyle was performed under general anesthesia. We removed 386 white loose bodies. Histopathologically, the loose bodies were consistent with synovial chondromatosis lesions. The postoperative course was uneventful, with no recurrence or TMJ dysfunction approximately 5 years after the surgery, indicating that open surgery is the best course of intervention in such cases.
Prolonged Recovery From General Anesthesia Possibly Related to Persistent Hypoxemia in a Draft Horse
Authors: Julien Dupont, Didier Serteyn, Charlotte Sandersen
Journal: Front Vet Sci (2018)
Keywords: anesthesia, estimated shunt fraction, horse, hypothermia, hypoxemia, recovery, residual drug effects
MeSH terms: Case Reports

Horses are susceptible to developing large areas of pulmonary atelectasis during recumbency and anesthesia. The subsequent pulmonary shunt is responsible for significant impairment of oxygenation. Since ventilation perfusion mismatch persists into the post-operative period, hypoxemia remains an important concern in the recovery stall. This case report describes the diagnosis and supportive therapy of persistent hypoxemia in a 914 kg draft horse after isoflurane anesthesia. It highlights how challenging it can be to deal with hypoxemia after disconnection from the anesthesia machine and how life-threatening it can become if refractory to treatment. Furthermore, it stresses the point on the interactions between hypoxemia and other factors, such as residual drug effects and hypothermia, that should also be considered in the case of delayed recovery from general anesthesia.
