BACKGROUND: Histological confirmation is needed when the pancreatic lesions is uncertain for neoplastic or nonneoplastic. Current case with multicentric @entity3123 showing indefinite clinical images was successfully diagnosed by a biopsy of a novel object expelled from the papilla. CASE PRESENTATION: A 71-year-old male was referred because of elevated serum pancreatic enzymes. Computed tomography revealed an unclear low-density area in the pancreatic body without evidence of @entity5 and mild dilation of the upstream main pancreatic duct (MPD). Other images, including abdominal ultrasound, endoscopic ultrasound, and magnetic resonance imaging, did not demonstrate cancerous findings. Endoscopic retrograde cholangiopancreatography showed a crab-claw-like obstruction in the MPD. Surprisingly, the component constituting the obstruction was moved by contrast injection and spilled out of the papilla orifice as a yogurt-like white object. Biopsy of this object by histology revealed a @entity5 cell clump. Pancreatectomy was performed, and pathology of the resected pancreas showed @entity5 replacing the acini and extending into the MPD. These @entity5 histologically resembled mixed @entity513 . CONCLUSION: Current report presented a rare @entity5 with multicentric pancreatic lesions, preoperatively diagnosed by a biopsy of an uncommon substance.

A case of multicentric pancreatic mixed XXXX diagnosed by a yogurt-like cell clump flowing from the papilla of Vater.
