REACTIVE PLASMACYTOSIS AT THE ONSET OF ANGIOIMMUNOBLASTIC T-CELL LYMPHOMA. CASE REPORT

Angioimmunoblastic T-cell lymphoma is a rare T-cell lymphoproliferative disease with generalized lymphadenopathy, hepatosplenomegaly, intoxication and polyclonal hypergammaglobulinemia. The persistence of plasma cells in peripheral blood can be a manifestation of both tumor and reactive processes. In our article, we described the case of angioimmunoblastic T-cell lymphoma with an increase in the number of peripheral blood plasma cells to 28 %, and in bone marrow to 9 %. The complex diagnostics, including plasma cells immunophenotyping, morphology of the lymph node biopsy and bone marrow samples, made it possible to verify the diagnosis of angioimmunoblastic T-cell lymphoma with polyclonal plasmacytosis.
