[Pemphigus vegetans, a rare variant of pemphigus vulgaris].

Pemphigus vegetans is a variant of pemphigus vulgaris with different clinical manifestations. Diagnosis may be difficult because of the varied presentations. A 46-year-old woman with this condition had been treated for Behcet's disease because of oral lesions. On admission, prior to dermatological consultation, she was thought to have an infectious disease. The diagnosis of pemphigus vegetans was confirmed by histological and immunofluorescence studies.
