Coexisting juvenile polyps and tubulovillous adenoma of colon with carcinoma in situ: report of a case.
The coexistence of juvenile and adenomatous polyps is confirmed by the present case of a 17-year-old girl who had two juvenile polyps and a tubulovillous adenoma of the colon with carcinoma in situ, a clinically benign lesion. The relation between the juvenile and adenomatous processes and the risk of the development of colonic carcinoma in such cases remain ill defined.
