Human herpesvirus type 8 and epstein-barr virus-associated cutaneous lymphoma taking anaplastic large cell morphology in a man with HIV infection.
Human herpesvirus type 8 (HHV-8, Kaposi's sarcoma-associated herpesvirus)-positive lymphoma taking anaplastic large cell morphology in the skin is described in a 46-year-old man with AIDS. Multiple erythematous nodules appeared on the trunk and extremities during the treatment of AIDS. Histological examination of cutaneous nodules showed dense infiltration of CD30 + atypical lymphoid cells in the deep dermis. Immunoglobulin JH gene rearrangement was detected in these lymphoma cells. Both Epstein-Barr virus-encoded small RNA and HHV-8 mRNA (T1.1/nut-1) were detected in these lymphoma cells by in situ hybridization. Remarkable retention of the pericardial fluid was observed at the same time that cutaneous lesions grew, and lymphoma cells in the pericardial fluid showed the same phenotype as the cutaneous lymphoma. Chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisone effectively reduced both the cutaneous nodules and pericardial fluid. However, the patient died 4 months after diagnosis because of cytomegalovirus infection. As far as we know, this is the first report of an HHV-8-positive cutaneous lymphoma taking anaplastic large cell morphology. This case suggests the association of AIDS-related anaplastic large cell lymphoma with HHV-8.
