Psoriasis and bullous pemphigoid are immunologically mediated diseases. Their concurrent occurrence has been described rarely in literature. The pathogenesis behind concomitant occurrence however remains unclear. The treatment modality of such patients differs from usual. We report a case of a 72 years old man with psoriasis vulgaris presenting with tense bullae, erosions and crusts. Histopathological examination was done to confirm the diagnosis of psoriasis pemphigoides, but the exact etiology could not be identified.
