Hidradenoma papilliferum (HP) is an uncommon benign cutaneous adnexal neoplasm of the anogenital region commonly seen in middle-aged, Caucasian females. Anastomosing and branching tubules, lined by columnar cells, and a basal layer of myoepithelial cells are the characteristic histopathological features. We report a case of HP in a 60-year-old female presented with a vulvar lesion. The case was evaluated for malignancy, with the initial histopathology showing extensive squamous metaplasia but ultimately found to have HP.
