Facial porokeratosis characterized by destructive lesions.

Porokeratosis is a rare group of keratinizing diseases. It is inherited as an autosomal dominant disease with variable penetrance, although sporadic cases are often reported. Porokeratosis has as its histological hallmark the typical cornoid lamella. Porokeratosis lesions localized on the face can vary from superficial to destructive in nature. Only 12 cases have been reported in the literature to date. We report one more unusual case of destructive facial porokeratosis.
