Large cholesterol polyp of the gallbladder mimicking gallbladder carcinoma.
Gallbladder tumors larger than 10 mm in diameter have a high incidence of malignancy. We report an extremely rare case of a large cholesterol polyp of the gallbladder mimicking gallbladder carcinoma. Ultrasonography and computed tomography showed a larger papillary mass in the fundus of the gallbladder with a maximum diameter of about 30 mm, the largest gallbladder polyp ever reported to our knowledge.

Colon stenosis caused by old portal vein thrombosis.
A 58-year-old female with a history of portal vein thrombosis was referred to our hospital with abdominal pain and distention. Colon fiber and enema of the colon showed stenosis at the transverse colon and the ascending colon, with edematous mucosa. Laparotomy revealed no abnormal findings other than chronic ischemia of the colon. To our knowledge, this is the first reported case of colon stenosis caused by portal vein thrombosis.
