title: A mixed mesodermal tumor of the cecum: report of a case.
abstract: We herein report the case of a 69-year old woman presenting with an abdominal mass, who was found to have a mixed mesodermal tumor (MMT) of the cecum. Imaging studies and endoscopic investigations were consistent with the diagnosis of a nonepithelial malignant tumor of the cecum. On laparotomy, a knuckle-sized firm mass involving the cecum was noticed. As a result, a right hemicolectomy was performed. Pathological examinations, including immunohistochemical staining, resulted in the diagnosis of mesodermal mixed tumor, homologous type. The patient was advised to undergo postoperative chemotherapy but she did not comply. She has been followed up as an outpatient and is still alive 1.5 years after the operation.
