T-cell/histiocyte-rich large B-cell lymphoma in a child:A case report and review of literature

T-cell/histiocyte-rich large B-cell lymphoma is uncommon in children population. There were few cases reported in the literature with wide range clinical presentations including advanced stage, and more involvement of liver, spleen and bone marrow. Head and neck lymphadenopathy tends to present in younger children. We report a case of 10-year-old boy who initially presented intermittent fever, headaches and neck lymphadenopathy. Subsequently, he developed diffuse lymphadenopathy and hepatosplenomegaly. T-cell/histiocyte-rich large B-cell lymphoma was diagnosed on a cervical lymph node biopsy. Cervical lymphadenopathy in this age group is most commonly reactive or nonmalignant processes. Lymphoma is much less frequent; mainly are non-Hodgkin lymphomas. However, a subset of large B-cell lymphoma called T-cell/histiocyte-rich B-cell lymphoma is rare in children.
