Liquen plano con ampollas: piense en liquen plano penfigoide

Lichen planus pemphigoides is a rare blistering disease of unknown etiology, characterized by the presence of blisters in patients with lichen planus. These may develop on lichenoid lesions or normal skin. The histopathology shows a subepidermal blister, and direct immunofluorescence reveals linear deposits of IgG and/or C3 along the basement membrane zone. We present a case of lichen planus pemphigoides in a 54 year-old woman that was not associated with any drug intake or underlying disease. She responded well to systemic corticosteroid therapy (Dermatol. Argent., 2013, 19(4): 286-288).
