[gamma-heavy chain production as an epiphenomenon in non-Hodgkin's lymphoma].
A 46-year-old woman was found to have localized lymphoplasmocytic lymphoma (low-malignancy non-Hodgkin lymphoma). Repeated recurrences required various chemotherapy courses with different drugs. Gamma heavy chains in serum and urine, as well as in blast cells in bone marrow, were first found 3 years later as part of a follow-up examination. When the lymphoplasmocytic lymphoma subsequently changed into a highly malignant disseminated large-cell lymphoma, the monoclonal gamma heavy chain-producing components no longer occurred. During continuing treatment and presumably selection of different cell clones the now terminal chemotherapy-resistant lymphoma again produced biclonal IgG heavy chains. The gamma heavy chain production added little to the histomorphological characterization of the underlying lymphoma, as well as its treatment and prognosis.
