Abstract
I report a case of inverted follicular keratosis in a 68-year-old woman who presented a solitary, asymptomatic, slightly brownish verrucous nodule on her nose, present for 3 years. The lesion was characterized histologically by focal hyperkeratosis, marked acanthosis, horn cysts, numerous squamous eddies and sebaceous differentiation of the basaloid cells in the epidermis.
