Abstract
A 77-year-old woman was admitted to the hospital for close examination of a SMT-like lesion of the stomach found in a periodic check-up after a mastectomy for right breast cancer 13 years earlier. Thorough examinations detected multiple masses around the stomach, but we could not make a decisive diagnosis. In the diagnosis of these intraabdominal tumors, a laparotomy was performed and peritoneal dissemination, lymph nodes swelling around the stomach and lymph angitis carcinomatosa were seen. The origin was unknown, but to remove the masses as much as possible, a distal gastrectomy, an omentectomy and a partial transverse colectomy were performed. Pathological examination revealed that the breast cancer operated on for 13 years earlier metastasized to lymph nodes and the peritoneum. Low-dose FP regimen was given repeatedly as postoperative chemotherapy. Two years have past and the patient has been free from recurrence. We report this rare case which showed peritoneal dissemination and metastasis to the perigastric lymph nodes after a mastectomy for breast cancer, together with some bibliographical consideration.
