Abstract
A 21-year-old woman visited a neighborhood clinic with the chief complaints of abdominal pain, constipation, and diarrhea. She visited our hospital when her symptoms became worse. Abdominal CT showed wall thickening of the transverse colon and a right ovarian tumor. Colonoscopy showed a circular stenotic lesion of the transverse colon. A trans-anal decompression tube was inserted to relieve the intestinal pressure. Laparoscopic partial colectomy for transverse colon cancer and right oophorectomy were performed. The histopathological diagnosis was signet-ring-cell carcinoma and metastatic ovarian tumor from colorectal cancer. The patient refused to undergo chemotherapy and left oophorectomy. She was detected as having peritoneal carcinomatosis 8 months postoperatively and died 5 months thereafter.
