Erythema Necroticans - A Case Report.

Erythema Nodosum Leprosum (ENL) is characterized by evanescent, erythematous, painful raised nodules which fade within 48-72 hours. Necrotic and ulcerative forms are rare presentations of severe ENL. A 27 year old male patient presented with multiple erythematous nodules on trunk and extremities associated with high grade fever, joint pain and pedal edema. Patient developed ulceration of nodules associated with pain and burning sensation over another 3 days. Slit smear showed clumps of granular bacilli. Biopsy showed superficial dermis showing edema with dense focal perivascular infiltrate of lymphocytes, macrophages and few scattered neutrophils. Fite-Faraco stain was negative. Patient was diagnosed as a case of erythema necroticans and started on oral steroids and thalidomide. The histological findings illustrate the need to consider leprosy diagnosis in necrotizing vasculitis even when Virchow's cells are not found in the infiltrate. Thalidomide is the drug of choice in such cases. This patient showed a marked response to the drug with healing of all ulcers within 2 weeks of starting thalidomide.
