title: Peripheral blood polyclonal plasmacytosis mimicking plasma cell leukemia in patients with angioimmunoblastic T-cell lymphoma: report of 3 cases and review of the literature.
abstract: Angioimmunoblastic T-cell lymphoma (AITL) is a unique type of peripheral T-cell lymphoma. Patients with AITL may have occasional reactive plasma cells present in the peripheral circulation. Prominent peripheral blood polyclonal plasmacytosis mimicking plasma cell leukemia, however, is distinctly uncommon. Here we describe 3 such cases from two large tertiary medical centers and discuss the role of ancillary studies in the differential diagnosis of peripheral blood plasmacytosis.
