title: [A five year follow-up of an HHV-8 related lymphoma in an HIV-negative elderly patient].
abstract: Primary Effusion Lymphoma (PEL) associated with the Human Herpes Virus 8 (HHV-8), is a rare type of non-Hodgkin lymphoma. It mainly strikes HIV-positive men. Five-year follow-up of a case of PEL HHV-8 related in HIV negative elderly man, is described. The patient was admitted to our Department for dyspnea, thoracic pain and persistent slight temperature. Chest radiography showed a left pleural effusion. Cytomorphological, immunohistochemical and molecular assays performed on pleural fluid, demonstrated the presence of a PEL HHV-8 related, in absence of Epstein-Barr virus (EBV) infection in the tumour cells. Serologic test for HIV (ELISA) resulted negative. Chest TC, taken after thoracentesis, showed marked thickening of diaphragmatic pleura. Because patient's age and general conditions, no chemotherapy was performed. Five years after diagnosis, clinical examination and chest tomographyshowed resolution of the described syndrome; particularly chest TC showed complete disappearance of diaphragmatic pleura thickening. This biological behaviour is unusually for PEL: medical literature shows that this lymphoma has a very poor prognosis; this case-report suggests, as already proposed from some authors, that PEL, in HIV-negative EBV-negative patients, is a distinct clinical entity, with a different clinical behaviour.
