Psoriasis vulgaris and lichen planus pemphigoid (LPP) represent two clinically well-characterized, chronic, inflammatory skin conditions. The concomitant occurrence of these two entities in a patient is rare. We hereby report a known case of psoriasis vulgaris later on presenting with clinical picture of lichen planus pemphigoides which was confirmed by histopathological examination and direct immunfluorescence. The etiopathogenesis of the coexistence of these two entities is not well known. Both diseases are immunologically mediated involving both cellular and humoral immune system.
We believe that this is the rare case report of psoriasis vulgaris coexistent with lichen planus pemphigoides.
