Primary subcutaneous mucormycosis (zygomycosis): a case report

A case of mycormycosis presenting primarily as a subcutaneous mass of the left leg in an immunocompetent individual is described. The mass that was diagnosed initially as a non-specific foreign body granulomatous process recurred a year later. Histopathological examination of the primary and recurrent lesions revealed partly degenerated hyphae associated with acute necrotizing and chronic granulomatous inflammation. Histomorphological features of primary subcutaneous mucormycosis without predisposing factors have not been previously reported.
