Copyright 2016 BMJ Publishing Group. All rights reserved.A 14-year-old boy previously misdiagnosed as having cutaneous anthrax was referred with a 2-month history of multiple wide and deep ulceronecrotic lesions in the lower extremities, which occurred after contact with animals. Skin biopsy was compatible with vasculitis. Further examination at our hospital elicited eosinophilia and a history of asthma. On the second day of hospitalisation, he developed deep vein thrombosis. A diagnosis of eosinophilic granulomatosis with polyangiitis (EGPA) was established and intravenous methylprednisolone was administered. The patient showed remarkable improvement of the cutaneous lesions. Diagnosis of EGPA is challenging in the vasculitic phase and necessitates a detailed history that specifically questions the patient for an asthma background. This case illustrates a severe cutaneous presentation of EGPA and emphasises the difficulty of diagnosis as a result of overlapped signs and symptoms with cutaneous anthrax and leukaemia. EGPA should be kept in mind in the differential diagnosis of cutaneous lesions associated with eosinophilia.
