Necrotizing leukocytoclastic vasculitis mimicking necrotizing fasciitis: a case report

Abstract

<p>There are several subtypes of necrotizing leukocytoclastic vasculitis, which are classified according to their morphological features in biopsy specimens using immunofluorescence microscopy. Necrotizing leukocytoclastic vasculitis is limited to the skin, predominantly that of the lower extremities, and usually spares the palms and soles. The most common skin manifestation is palpable purpura. Other skin manifestations include maculopapular rash, bullae, papules, nodules, ulcers and livedo reticularis. There is no specific laboratory test to determine the diagnosis. There are various diseases presenting with these nonspecific symptoms, and a rapid differential diagnosis must be conducted, because the appropriate differentiation and diagnosis markedly influence the treatment strategy and survival of patients. In this study, we report a case of necrotizing leukocytoclastic vasculitis<strong> </strong>presenting with internal organ involvement and symptoms of necrotizing fasciitis, with emphasis on the clinical differentiation.</p>
