ADRIANO, André Ricardo et al. Pemphigus vegetans induced by use of enalapril. An. Bras. Dermatol. [online]. 2011, vol.86, n.6, pp.1197-1200. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962011000600023.
Pemphigus Vegetans was first described as a variant of Pemphigus Vulgaris in 1876 by Neumann. In 1889, Hallopeau described a patient with pustules and vegetating plaques, suggesting that it would be a variant of Pemphigus Vegetans of Neumann. Both types of Pemphigus Vegetans are characterized by the development of vegetating plaques especially on skin folds (axillae, groin, perianal region). The authors present and discuss a case of Pemphigus Vegetans with an unusual clinical presentation lacking involvement of mucous membrane and flexor surfaces in an elderly female patient, associated with the use of enalapril as possible trigger factor. Clinical and histological diagnosis were suggestive of Pemphigus Vegetans of the Hallopeau type.
