[A case of cecal cancer with abdominal wall abscess]

A 63-year-old woman was admitted to our hospital for a palpable mass and abdominal pain. Abdominal CT showed an abscess in the abdominal wall and a contiguous mass in the intraperitoneal cavity. After drainage of the abscess was performed, we conducted a colonoscopy to investigate the cause of the mass. It revealed a type 2 tumor and a whole-circumferential stenosis in the cecum. It required preoperative chemotherapy with CPT-11 and S-1 to achieve radical cure characteristics with the operation. Because there was tumor reduction, right hemicolectomy and resection of the abdominal wall were performed. The patient was discharged 15 days after the operation with an eventful clinical course. Although 5 years have passed since the operation, she is alive and has had no recurrence. This patient accepted tumor reduction by chemotherapy , and the abdominal wall deficit that resulted from excision did not have it was it with a small range, and to rebuild the abdominal wall. The utility of preoperative chemotherapy is recommended in colon cancer which invades other organs.
