RARE NON-HODGKINS-LYMPHOMAS IN PATIENTS W ITH HUMAN-IMMUNODEFICIENCY-VIRUS INFECTION - 2 CASES WITH BONE-MARROW INVOLVEMENT

Malignant non Hodgkin's lymphomas in patients with acquired immunodefi ciency syndrome are usually of high grade and have a B-cell phenotype. We describe two cases of rare lymphomas during acquired immunodeficie ncy syndrome: one case of pleomorphic T cell lymphoma with medium and large cell predominance, of high grade of malignancy, according to the updated Kiel classification, involving mainly the bone-marrow, and on e case of low grade monocytoid B-cell lymphoma with bone-marrow extens ion, which is a rare condition in this type of lymphoma. These lymphom as seem to be a casual event during acquired immunodeficiency syndrome , but the immunodeficiency can be responsible of a more aggressive beh avior.
