Abstract

Follicular center cell lymphomas often contain a prominent population of T cells, most commonly in the interfollicular regions and with a helper immunophenotype. We report a case of follicular center cell lymphoma (follicular, mixed cell types) with a prominent population of T cells (normal CD4-CD8 ratio) in both the interfollicular and follicular regions. The prominent T-cell population resulted in misleading flow cytometric immunophenotypic findings. Immunoperoxidase stains (L-26, LN-2, and Bcl-2) confirmed the neoplastic follicular center cell origin and aided in subclassification.
