RESUMEN
Colonic muco-submucosal elongated polyp (CMSEP) is a rare disease which has been firstly reported by Matake. Only 21 cases have been reported since 1994. Although the mechanism of generation of such polyps remains unknown, their elongation may be caused by intestinal motion for a long period. The occurrence sites were distributed throughout the colon, excluding the rectum. CMSEP is coverd with normal mucosa and consisted of edematous, loose, fibrous, connective tissue and dense, fibrous submucosal layer, often dilatation of blood vessels and lymphatics. We present a case of CMSEP diagnosed by a colonoscopic polypectomy.

Granulomatous pancreatitis is a rare disorder and recognized rarely during life or non-operatively. Noncaseating granulomas in the pancreas, histologically indistinguishable from sarcoidosis, can be seen in a variety of diseases such as tuberculosis, fungal infection, berylliosis, Hodgkin's disease, non-Hodgkin's lymphoma and Crohn's disease. Therefore, as with other granulomatous diseases, a tissue biopsy is essential for the diagnosis. Its clinical presentation is often similar to pancreatic cancer, with common presenting symptoms including abdominal pain, weight loss, jaundice, and anorexia. We report a case of idiopathic granulomatous pancreatitis in a 56-year-old women whose clinical and radiographic findings were suggestive of pancreatic cancer.

Anomalous union of pancraeticobiliary drain (AUPBD) is uncommon anomaly of the pancreaticobiliary ductal union system. Usually, this anomaly is confirmed by long common channel (>15 mm) at ERCP and is divided into according to relationship between pancreatic duct and common bile duct. Recently several reports showed that AUPBD may be associated with congenital choledochal cyst and gallbladder carcinoma. A 33-year old man was admitted with RUQ pain and jaundice. Ultrasonography, Abdominal CT, ERCP, and PTBD cholangiography showed type I choledochal cyst, AUPBD and focal adenomyomatosis on the gallbladder. Whipple's operation with excision of the choledochal cyst and chloecystectomy were performed for treatment. This clinical experience suggests that high incidence of choledochal cyst in patients with AUPBD and gallbladder adenomyomatosis are may be closely related to the carcinogenesis of gallbladder cancer in patients with AUPBD.

Liposarcoma in esophagus is rare, moreover the pedunculated form is very rare. We experienced a case of liposarcoma in a 36-year-old man who had intermittent swallowing difficulty for 7 months. Endoscopy and esophagography revealed that a smooth longitudinal tumor mass occupied the esophageal lumen. Esophagotomy and surgical excision was done. The tumor was 4 cm in length and 3 cm in average diameter with an obvious stalk measuring 3.5 cm in length and 1.5 cm in diameter. Microscopic examination disclosed a lipoma with focal ulceration and liposarcomatous change infiltrating into interstitial fibrous tissue at its distal end.
