Abstract
A case of pedunculated lipoma of the duodenum is reported. A 58-year-old man was admitted to our hospital complaining of fatigue and a loss of appetite. Barium X-rays (hypotonic duodenography) and endoscopy revealed a pedunculated tumor with erosion at the tumor head in the 2nd portion of the duodenum. The head of the tumor was covered with intact duodenal mucosa except for the part involved with erosion, and the erosion was attached with whitish coat. The tumor was diagnosed as a submucosal tumor of the duodenum. The surgically resected tumor was 2.7×2.1×1.9 cm in size and diagnosed his-tologically as benign lipoma derived from the submucosal layer of the duodenum. Fifty-six cases of duodenal lipoma including ours are reported in the literature up to 1987 in Japan. The clinical features of these cases are also discussed.
