[Colorectal cancer in pregnancy. A case report].

Carcinoma of the colon-rectum during pregnancy is rare (0.1-0.001%). Prognosis is severe as it is generally made at an advanced stage. The Authors report a case of adenocarcinoma of the recto-sigmoid junction in a 26-year-old pregnant woman. In this patient diagnosis was occasionally made after delivery by cesarean section. Early diagnosis is difficult because symptoms of colorectal cancer (vomiting, constipation, anemia, rectal bleeding, abdominal pain and distension, etc.) can be related to pregnancy. Gestational age and operability of the tumor are discussed by current medical and surgical management.
