A slowly enlarging arm ulcer appeared in a 61-year-old man with cutaneous T cell lymphoma. Skin biopsy revealed aseptate hyphae and nodular small/medium-sized pleomorphic CD4(+) T cell infiltration. Cultures yielded Absidia corymbifera which was identified by phenotypic and molecular methods. Since a thorough examination did not detect organ involvement, the patient was diagnosed as having primary cutaneous zygomycosis. This is the first case report of cutaneous zygomycosis caused by A. corymbifera in a patient with primary cutaneous CD4(+) small/medium-sized pleomorphic T-cell lymphoma. Other cases of primary cutaneous zygomycosis caused by A. corymbifera are also reviewed.
