Retrorectal cyst-hamartomas. Report of two cases with adenocarcinoma developing in one.

Both lesions were characterized by the presence of cysts lined by mucus-producing, ciliated and transitional epithelium. The anatomical and histological findings in our cases of retrorectal cyst-hamartoma are in favor of an embryologic origin from remnants of the postanal gut.
