Benign apocrine lesions have been described in the anogenital region, although according to the World Health Organisation convincing examples of anal apocrine adenocarcinomas have not been published. This report describes the case of an invasive apocrine adenocarcinoma arising in a benign adenoma in the perianal region of a 45 year old woman. The origin and invasiveness are supported by histological and immunohistochemical studies.
