title: [Multiple myeloma in a patient in remission from malignant lymphoma].
abstract: A 71-year-old man was admitted because of right cervical lymph node swelling in February 1986. Lymph node biopsy revealed that he suffered from diffuse, large cell malignant lymphoma. Immunological staining showed lymphoma characterized by B cell markers, IgG, kappa type. Bone marrow aspiration, revealed no evidence of lymphoma and 0.2% plasma cells. The clinical stage was IIA. The patient was treated with the CHOP regimen (doxorubicin, cyclophosphamide, vincristine and prednisolone), which achieved complete remission. In October 1988, he was re-admitted because of a subcutaneous abscess, and biopsy of the inguinal lymph node showed reactive lymphadenitis. Although he improved with antibiotic therapy, laboratory date on admission showed monoclonal gammopathy. Serum immunoelectrophoresis demonstrated a monoclonal bow of IgA kappa type, and bone marrow aspiration revealed hypercellularity with an increased number of plasma cells (76.8%). The patient was diagnosed as having multiple myeloma, and combination chemotherapy was begun. He now attends the out-patient department at our hospital. The development of multiple myeloma has not been reported previously during a course of malignant lymphoma. Although the association of these two B cell neoplasias was unknown, in this case both showed the characteristic of kappa type light chains. This case may provide information concerning tumor cell origin.
