A 59-year-old man with a history of rectal cancer, Behget's disease, Hodgkin lymphoma and ascending-colon cancer, and suffering from gastric cancer was found during distal gastrectomy to have a 3cm lesion in the transverse colon. We partially resected the transverse colon, for which pathological findings indicated a myofibroblastic tumor. Seven months after his latest surgery, he suffered right subcostal pain, and computed tomography showed multiple low-density areas in the liver. Pathological findings from the liver biopsy indicated myofibroblastic tumor, the same as for the transverse-colon tumor. After hepatic artery chemotherapy with mitomycin C and degradable starch microspheres in seven courses, he died of hepatic failure.
- Gastrointestinal mesenchymal tumor
- Multiple malignancy
