title: [Local resection of a rectal carcinoid tumor using Mason's trans-sphincter technic].
abstract: We present an infrequent clinical case of rectal carcinoid tumor in a 65-year-old male. The treatment of this tumor is always surgical and selection of the technique is determined by the patient's age, the size and location of the neoplasm and particularly by the presence of invasion of the muscular layer in the pathology study. Simple excision of tumors under 2 cm. and abdominoperineal or low anterior resection of lesions over 2 cm. are recommended. Mason's trans-sphincter approach can be indicated in cases like ours, which permits an ample excision with margins of safety and functional conservation of the anal sphincter structure.
