ABSTRACT

This article reviews several miscellaneous tumors of the rectum. Carcinoid tumors of the rectum are uncommon tumors arising from cells of the gastrointestinal neuroendocrine system with a wide range of biologic activity. Evaluation of these tumors includes endoscopy, endoscopic ultrasound, magnetic resonance imaging, computed tomography, scintigraphy, and a variety of histologic techniques. Treatment is based on the risk of lymph node and distant metastases. Hemangiopericytomas are rare vascular tumors, which may arise from the pelvis or retroperitoneum. Their evaluation and treatment are discussed. Leukemic infiltration of the colon and rectum is well described in autopsy studies and is being identified with greater frequency endoscopically. Treatment is aimed at the underlying disease process, although radiation has been used in some cases.
