[Lymphoblastif lymphoma (contribution to its prognosis)].

The authors report a case of lymphoblastic lymphoma in a woman of 41 years, with characteristic skin lesions, long evolution and relative benignity (good general condition, lymph nodes, liver and spleen not palpable, and the bone marrow study was normal). We wish to underline the existence of a Monoclonal Disglobulinemia (Paraproteins in the zone of Inmunoglobulin M); this observation was made in some cases of leukemia. This laboratory data would be of a prognostic value, indicating a rapid malign evolution, in contrast with other clinical and laboratory manifestations.
