[Immunoblastic lymphoma as expression of the final phase of IgA multiple myeloma]

We present the case of a patient diagnosed of IgA multiple myeloma who, four months after being diagnosed and after four cycles with VCAP with good response, showed high fever and constitutional syndrome; multiple subcutaneous nodules appeared during his hospitalization. Biopsy of the bone marrow, and of one of the nodules showed an immunoblastic lymphoma. Even with treatment the patient died due to a pneumonia and a digestive hemorrhage.
