A case of retro-auricular panfolliculoma mimicking basal cell carcinoma: A rare adnexal tumor with a review of the literature.

Panfolliculoma is a rare slow growing adnexal tumor, characterized by differentiation toward all parts of the hair follicle including the infundibulum, isthmus, stem, and bulbs. Clinically this adnexal tumor may mimick basal cell carcinoma and other adnexal neoplasm including trichoblastoma and trichoepithelioma. In this study, we present a rare case of slow-growing retro-auricular panfolliculoma of a 70-year-old female mimicking basal cell carcinoma that was successfully excised without recurrence.
