Captopril-induced pemphigus vegetans with Charcot-Leyden crystals.
A 78-year-old woman developed intertriginous vegetating plaques, mouth ulcers, and a cerebriform tongue after 11 months of captopril therapy. Findings of clinical, histologic, and immunofluorescence testing were consistent with a diagnosis of pemphigus vegetans. In addition, Charcot-Leyden crystals were observed within some of the intraepidermal, eosinophilic abscess cavities, which were bordered by granular cells undergoing keratinization. The skin lesions cleared rapidly after discontinuation of captopril. To the best of our knowledge, this report describes the first case of pemphigus vegetans induced by captopril.
