Intestinal perforation due to metastasis of breast carcinoma, with special reference to chemotherapy: a case report.

We report a case of small-bowel perforation due to metastatic carcinoma of the breast during chemotherapy. Partial resection of the small intestine and primary anastomosis were performed. Although the patient made a good recovery from panperitonitis, she died of the disease on the 55th postoperative day. Since perforation during chemotherapy results in an extremely poor prognosis, special caution during chemotherapy is needed for patients with possible gastrointestinal involvement with tumor.
