Primary duodenal carcinoma is rare. Duodenal mucinous adenocarcinoma (DMA) is even rarer, and its associated manifestations and typical endoscopic or imaging findings are not well characterized. Herein, we report a case of primary DMA in an asymptomatic 58-year-old man who visited our hospital for a regular health screening. Upper endoscopy revealed an approximately 4-cm lesion in the second portion of the duodenum, but the mass was not visualized on computed tomography. Biopsies revealed a tubular adenoma that was subsequently resected. Frozen biopsies demonstrated DMA with a background of low-grade tubular adenoma for which we performed Roux-en-Y duodenojejunostomy and jejunojejunostomy. To our knowledge, this is the first report of a patient with DMA in Korea.

Development of biliary casts is very unusual, especially in patients who have not undergone liver transplantation. Variable causes of biliary cast formation in nonliver transplantation patients have been suggested. However, stasis of bile flow and/or gallbladder hypocontractility is known to eventually result in the promotion of biliary sludge and subsequent cast formation. Here we present one case of biliary cast syndrome, which developed in a nonliver transplant patient who had biliary sludge for a long period of time, providing evidence that long-standing biliary sludge may lead to cast formation.

Synovial sarcoma is a rare type of soft tissue sarcoma that arises in tissues containing synovial fluid, usually in the extremities. It has only rare occurrence in the retroperitoneal space. Early detection of retroperitoneal synovial sarcoma is difficult, since the retroperitoneal space is highly expandable and deeply hidden. Furthermore, the presenting symptoms are often vague and nonspecific, and are related to the pressure on adjacent structures. In this study, we present an unusual case of retroperitoneal synovial sarcoma with obstructive jaundice due to intrabiliary blood clots caused by invasion of bile duct by tumor. The obstructive jaundice was relieved through endoscopic removal of the blood clots and insertion of a biliary stent.
