Carcinoid Tumor of the Rectum; a Case Report

A case of rectal carcinoid of 2 mm in diameter was reported. This tumor was discovered in a 55-year-old man on a hemorrhoidectomy and excised. Most of rectal carcinoids were discovered on routine rectal examinations or rectal operations, because they are clinically asymptomatic. The distinction between carcinoids which are clinically benign and those which are malignant can be made only by determining the extent of invasion of the bowel wall or by evidence of metastasis. The gross size of the tumor is important, since most tumors less than 2 cm in diameter are localized, whereas those 2 cm in diameter or larger have invasion and metastasis. Benign rectal carcinoids should be treated with local excision. However, malignant rectal carcinoids should be treated by radical resection.
