title: Value of biopsy in diagnosis of primary lymphosarcoma of marrow.
abstract: We report the clinical, hematologic, and survival characteristics of 12 patients with lymphosarcoma primarily involving the marrow but without substantial nodal disease. The importance of the biopsy in establishing this diagnosis is stressed, since in 7 of the 12 cases the diagnosis would not have been made had only a marrow aspiration been performed.
