It is characterized by lymphomatous effusions in different serous body cavities without the presence of a detectable tumor mass. The diagnosis is challenging and the clinical outcomes are poor. Aim: The aim of this paper is to report a rare case of PEL in a man who have sex with women (MSW) with HIV-1/2 infection, history of visceral Kaposi sarcoma (KS) and the development of a seronegative arthritis previous to the lymphoproliferative disease diagnosis. PEL presented with ascites, was treated with high-dose chemotherapy and autologous stem cell transplantation, with a good clinical outcome. Case Presentation: We describe a case of a 48-year-old HIV-1/2-infected patient from a high HHV8 seroprevalent country, hospitalized following a three-month history of increased abdominal volume and general constitutional symptoms. Laboratory data revealed normocytic normochromic anemia and a high level of lactate dehydrogenase. A diagnostic paracentesis was performed with cytology compatible with high-grade B-cell lymphoma. Peritoneal fluid cytology showed large lymphoid cells expressing leucocyte-common antigen CD45 without expression of the CD20 antigen (B-lymphocytes) and positivity for HHV8 by immunocytochemical staining, compatible with the diagnosis of PEL.展开更多
