Anti-neutrophil cytoplasmic antibody - negative Churg-Strauss syndrome presenting as non-healing ulcer on finger and associated lichen amyloidosis: a case report

Churg Strauss syndrome (CSS) also known as eosinophilic granulomatosis with polyangitis (EGPA), is a rare disease manifested by hypereosinophilia, vasculitis and extravascular granuloma. We report a case of 72 year old male with history of asthma and allergic rhinitis who presented with non-healing ulcer on dorsum of left middle finger and petechial lesions on forearms. Investigations revealed marked eosinophilia, elevated IgE, negative antineutrophil cytoplasmic antibodies (ANCA), histopathologic examination showed granulomatous vasculitis and CSS was diagnosed using ACR criteria. We report this case because of rarity of disease and the importance of recognizing similar presentation for early diagnosis and treatment of this life threatening syndrome.
