Abstract
Case 1. A 56-year-old man visited our hospital with right lower abdominal pain. Barium enema study and colonofiberscopic examination showed a smooth and caterpillar-like semipedunculated lesion of the cecum (Figure 1, 2). Under the diagnosis of a submucosal tumor colonof iberscopic polypectomy was underwent and the resected specimen showed a submucosal lipoma (Figure 3). Case 2. A 74-year-old woman visited our hospital with anal discomfort. Barium enema study and colonof iberscopic examination showed a smooth, yellowish and ovoid semipedun-culated lesion of the cecum (Figure4, 5). Under the diagnosis of a submucosal lipoma, colonof iberscopic polypectomy was underwent and the resected specimen showed a submucosal lipoma (Figure 6). Lipoma of the large intestine has been reported amounting to about 100 cases throughout Japan. Thirty-two cases were observed endoscopically and endoscopic polypectomy was performed in only 11 cases (Table 1). As most cases of lipoma of the large intestine reported are semipedunculated or pedunculated, the endoscopic polypectomy may be the main therapeutic method of the disease under the careful selection of the indication.
