Cutaneous mucormycosis

We report two cases of primary cutaneous mucormycosis in immunocompromised patients. Although their clinical presentation showed nonspecific necrotic ulcers, the histopathologic features were diagnostic. In both cases, broad, branching, nonseptate hyphae were found in the dermis and subcutaneous tissue. In one case the hyphae could be observed in the epidermis. To our knowledge, this is the only reported case of primary cutaneous mucormycosis with hyphae detectable in the epidermis.
