A case is reported of an unusually large (8 cm × 6 cm) carcinoid tumor of the transverse colon. The patient had marked anemia but no severe symptoms of obstruction although the bowel lumen proved to be almost completely occluded. Since the pathologist found no evidence of malignancy in the tumor nor of metastasis in the fourteen lymph nodes examined, surgical removal may prove to be curative. © 1969 The American Geriatrics Society.
