title: Colon cancer during pregnancy. A case report.
abstract: BACKGROUND
  The reported incidence of cancer during pregnancy is between 0.07% and 0.1%. The incidence of colorectal carcinoma in pregnancy was 1 per 13,000 liveborn deliveries during 1981-1989.
  
  
  METHODS
  A 33-year-old woman, gravida 2, para 1, was admitted at 30 weeks' gestational age with a history of rectal bleeding and right upper quadrant pain. Abdominal ultrasound and magnetic resonance imaging revealed a mass located on the posterior part of the right liver and a fetus with vertex presentation. Primary cesarean section and a right hemicolectomy and wedge biopsy from the metastatic lesion on the right side of the liver at 34 weeks' gestation was performed. Histologic examination confirmed serosal and lymph node invasion of moderately differentiated mucous-secreting adenocarcinoma of the cecum and adenocarcinoma metastatic to the liver. The patient received systemic chemotherapy.
  
  
  CONCLUSIONS
  Only 1 of 41 cases of colon cancer during pregnancy above the peritoneal reflection has been reported to be localized to the cecum. Our case is the second such one. Women with colorectal carcinoma during pregnancy usually have a poor prognosis, which may be attributable to younger age and delay in diagnosis since the initial symptoms often are presumed attributed to normal pregnancy, as in this case.
