Granular Cell Myoblastoma is typically encountered in the skin, subcutaneous tissue nr oral cavity, but was rarely been found in the large intestine. In a series of 110, the two were in the cecum(18). Both patients, 36-and 43-year-old women, underwent radial excision of the lesion because of the clinical impresaion of the malignancy. The other Three patients with granular cell myoblastoma of the cecum, all asymptomatic and found incidentally, have been reported. From the available data, one was a man(22) and two were women (26,27). They were 17 (27), 40(26) and 71(22) years of age. One lesion, in the cecum, was excised at laparotomy that was performed under the irnpression of acute appendicitis, and disclosed a small polypoid submucosal nodule in the cecum incidentally(27). Another lesion, in the cecum, was excised at laparotomy following the discovery of a small cecal defect on barium enema examination 9260. The other lesion, in the cecum, was found at autopsy(22), This paper reports a case of granular cell myoblastoma of the cecum, including its colonoscopic finding.
