Abstract

The anal canal is the most distal part of the gastrointestinal tract, and it is developed and formed during the embryonic period. Infection is the most common disease process that occurs around the anorectum, yet tumors or cysts are occasionally encountered. The abnormal development of these parts of the gastrointestinal track during the embryonic period can result in congenital lesions that are discovered in young children or adults. A 72-year-old woman presented to us with postprandial lower abdominal discomfort and fecal incontinence. An anorectal mass was felt on the rectal examination. The colonoscopy demonstrated a submucosal tumor that was closely located to the anorectal junction. The tumor was excised with a snare and it was diagnosed as an anal gland cyst due to the histologic features. It is necessary to differentiate anal gland cyst from the other diseases that have submucosal characters, such as carcinoid tumor. (Korean J Gastrointest Endosc 2006;33:121⁣124)
