Perianal papillary hidradenoma

Hidradenoma papilífero perianal

Papillary hidradenoma is a rare benign neoplasm characterized by the presence of cystic and papillary structures that usually occurs on the vulva but has also been described in other locations. We report the case of a 74 year-old woman with a perianal papillary hidradenoma. An initial diagnosis of Kaposi's sarcoma was made. In order to prevent mistaken diagnoses, this report aims to emphasize this lesion is not limited to the vulva and may appear in other locations.
