title: Lupus erythematosus vegetans.
abstract: A 29-year-old woman with known systemic lupus erythematosus presented with exudative and vegetative plaques bilaterally on her groins. The clinical and histological findings indicated a diagnosis of pyodermatitis vegetans. Direct immunofluorescence studies revealed the presence of a definite basement membrane zone band for IgG, IgM and C3, favouring lupus erythematosus. We propose the term lupus erythematosus vegetans for this combination of clinicopathological and immunohistological findings.
