Post-surgical zygomycotic necrotizing subcutaneous infection caused by Absidia corymbifera

Necrotizing infections of the skin and subcutaneous tissue are usually bacterial in origin. Rarely, fungi of the class Zygomycetes, which cause deep mycoses, may be responsible for acute necrotizing infections of these areas. Several local and systemic predisposing factors have been associated with such acute necrotizing infections. Surgical debridement and amphotericin B remain the mainstay of treatment. In this report we describe a patient with post-surgical necrotizing subcutaneous infection caused by Absidia corymbifera, 2 weeks following appendectomy. Successful management with surgical debridement, topical amphotericin B and oral potassium iodide is reported.
