Retrorectal cyst hamartoma (RCH) is a rare benign cystic lesion located in the retrorectal space. Malignancy arising in such lesions is very uncommon. In this study, 2 cases of mucinous adenocarcinoma arising in RCH are presented. In one case, dysplastic epithelium lined the cyst wall, surrounding the area of carcinoma and suggesting a dysplasia-carcinoma progression in RCH. Adenocarcinoma and the dysplastic epithelium were strongly positive for p53 and Ki-67 and showed negative staining for p21 by immunohistochemistry. These findings are suggestive of a mutation in the p53 gene in the adenocarcinoma and in dysplastic epithelium lining the cysts, similar to the dysplasia-carcinoma sequence described for the development of colonic adenocarcinoma.
