title: Inverted follicular keratosis.
abstract: We reviewed 17 cases of inverted follicular keratosis. The median age of the patients at the time of surgery was 69 years. Follow-up in 14 cases showed no recurrences of inverted follicular keratosis, which is a benign skin lesion, often mistaken clinically and pathologically for a malignancy. Inverted follicular keratosis is characterized histologically by the presence of squamous eddies, acantholysis, acanthosis, and hyperkeratosis.
