Abstract
A case of colon cancer in pregnancy is reported. A 37-year-old pregnant woman visited a nearby hospital because of diarrhoea and bloody stool, which developed in the later period of pregnancy. She was diagnosed as gestosis and underwent cesarean section. After the surgery, however, bloody stool still continued and she was referred to the hospital. As a result of various examinations, an advanced colon cancer was found in the ascending colon and right hemicolectomy was performed. Histological diagnosis was well-differentiated adenocarcinoma, pm, ly1, v0, n1, ow(-), aw(-), absolute curative operation.
Colorectal cancer in pregnancy is rare. It is said that one or two among 100, 000 pregnant women may have the disease. An association of colonic cancer is particularly rare, and only 36 cases can be seen in the Japanese literature. This case was the 37th one. In view of this possible association in pregnant women, we would emphasize the importance of early detection and early diagnosis by appropriate examinations.
