In a 29-year-old male complaining of constipation, total colonoscopy r
evealed a 5 mm yellowish submucosal tumor at a distance of 6 cm from t
he anal ring. The histologic diagnosis of specimens obtained by biopsy
was rectal carcinoid tumor and transanal ultrasonography revealed the
tumor localization within the submucosal layer in the rectum. A strip
biopsy was performed. Histopathological examination confirmed the dia
gnosis and ascertained complete excision. Rectal carcinoid tumors shou
ld be removed completely and strip biopsy may be a suitable procedure
for removal of rectal submucosal tumors less than 10 mm in diameter.
