Verrucous Psoriasis - Atypical Variant of Psoriasis Vulgaris

Abstract

Verrucous psoriasis is a rare variant of hypertrophic psoriasis, characterized by erythematous to hyperpigmented verrucous plaques, usually recalcitrant to treatment. Here we discuss a case of verrucous psoriasis which mimics various dermatological conditions like extensive verruca vulgaris, chromoblastomycosis, verrucous carcinoma, tuberculosis verrucosa cutis, elephantiasis nostras verrucosa. It might be associated with diabetic mellitus, lymphatic obstruction, vascular pathology, repeated trauma or immunosuppression. In my case, verrucous psoriasis is associated with chronic venous insufficiency with ulcer.
