[Multiple granular cell tumor of the colon]

With reference to a case of multiple colorectal granular cell tumors, the authors briefly review the literature concerning this unusual tumor localization. This case demonstrates the most common appendicular, caecal and rectal forms among the localizations of colonic granular cell tumors: as well as the possible proliferation of many other tumors especially in caecal localizations. However the course of the disease is slow, and at the present time only one case report of malignant colonic TCG has been published.
