Coexistance of Pemphigus Vulgaris and Psoriasis in a Middle Aged Man

Psoriasis and pemphigus vulgaris are two inflammatory and autoimmune diseases. Their concomitant occurrence in one patient is very rare. We describe a 57-year-old patient with a history of severe plaque type psoriasis for 2 years. After a few months, he presented with disseminated bullae and mucosal erosions which were documented as pemphigus vulgaris. Both of the diseases were successfully controlled with rituximab, prednisolone and weekly methotrexate.
