Bullous eczema presenting as bullous pemphigoid-like eruption: A case series

Abstract

Bullous pemphigoid (BP) is an autoimmune blistering disease resulting from autoantibodies directed against BP180 and/or BP230 proteins. BP is traditionally diagnosed based on clinical features, histologic assessment of cutaneous biopsies, direct (DIF) and indirect immunofluorescence (IIF) studies, and/or enzyme-linked immunoassay (ELISA) analysis. We here report, 6 elderly patients who presented with multiple tense bullae, clinically mimicking BP in the absence of detectable autoantibodies by DIF, IIF, and ELISA for BP-180, BP-230, and type VII collagen autoantibodies.
