@entity5 generally appear as yellow/gray or tan submucosal nodules. We experienced a case of pedunculated @entity4303 showing a mushroom-like appearance. The case was a forty years old @entity1 who was admitted to our hospital due to @entity548 . Colonoscopy revealed a pedunculated polyp presenting a mushroom-shaped appearance measuring 13 mm in diameter in the rectum. The histological diagnosis of specimens obtained by biopsy was @entity420 and transanal ultrasonography revealed the @entity5 localization within the submucosal layer in the rectum. Endoscopic mucosal resection (EMR) was performed. Histopathological examination established the diagnosis of @entity5 in the rectum. Frequencies of the pedunculated @entity4303 were reported to be 2.4% to 7.1% in the literature. Because of its rarity, pedunculated configuration may confuse the endoscopic diagnosis of @entity4303 . Treatment for @entity4303 of 1 to 1.5 cm in size remains controversial. Although such @entity5 are technically respectable by EMR, careful attention must be paid in dealing with these @entity5 because there may be unexpected behaviors of the @entity5 .
