title: [Pemphigus vegetans. A historical perspective].
abstract: Pemphigus vegetans is a rare variant of pemphigus which is mainly localized in the intertriginous areas (Neumann type, Hallopeau type) or primarily involves the mucous membranes (pyostomatitis vegetans). A 18-year-old patient with erosive stomatitis developed a vegetating plaque with papillomatous and verruciform features in her left axilla. Histopathological examination of the axilla revealed papillomatosis and acanthosis as well as suprabasal clefting with acantholytic cells. By direct immunofluorescent examination, deposits of immunoglobulin IgG and complement (C3) were found in the intercellular space of the epidermis. Serological examination by indirect immunofluorescent techniques was indicative of pemphigus autoantibodies at a titer of 1:40. This case report demonstrates that the classical differentiation of pemphigus vegetans in two types, Neumann type and Hallopeau type, is mainly of historical importance, because both entities may represent variants of the same disease. In addition, other disorders such as IgA pemphigus may also present with vegetating plaques in intertriginous sites.
