Carcinoma in the Gardner syndrome: a case report

Carcinoma of the colon is commonly seen in the Gardner syndrome and familial polyposis of the colon. Therefore early detection of these symdromes in families and careful follow-up are important. During a study of families at high risk of developing colorectal cancer, an asymptomatic 19-year-old female was found to have the Gardner syndrome. Although barium enema examination was negative, colonoscopy revealed the presence of polyps; biopsy of one polyp revealed carcinoma-in-situ.
