A Case of Primary Bone Marrow B-Cell Non Hodgkin’s Lymphoma with Severe Thrombocytopenia: Case Report and A Review of the Literature

摘要

A 78-year-old man presented with persistent gingival bleeding. He had low platelet count of 1.0 × 109/L without any lymphadenopathy. Bone marrow specimen showed diffusely distributed small-sized lymphocytes. Combined with immunophenotypic analysis, a diagnosis of primary bone marrow B-cell non-Hodgkin’s lymphoma was made. Thrombocytopenia was considered to be caused by autoimmune destruction of platelets.
