Sapnashree Bhaskar et al. Indian Dermatol Online J. 2015 Mar-Apr.

Abstract

Porokeratosis is a disorder of epidermal proliferation in which many different clinical variants can be distinguished. Herein we report a rare case of porokeratosis involving almost all parts of the body with simultaneous occurrence of various forms of the disease in the same individual (classical porokeratosis of Mibelli, disseminated superficial actinic porokeratosis, hypertrophic porokeratosis, and genital porokeratosis).

Keywords: Porokeratosis; rare coexistence; uncommon sites.
