Aplasia eritroide pura secondaria a disturbo linfoproliferativo cronico midollare primario a cellule B. Un caso inusuale

Acquired erythroblastopenia is rather rare, more frequent in adult or old male. In absence of anti EPO antibody, it's associate to inhibition of the erythroid growth mediated by suppressive T lymphocytes, generally T8 or NK or mediated by IgG antibody in association with timoma, lymphoproliferative or immunological disorders, and other diseases. The course usually is chronic and follows that of the associate pathology. We report a case with pure red cell anaemia associated to non classified medullary B cell lymphoproliferative disorder in an old woman with complete remission after steroid therapy.
