High-Grade B-Cell Neoplasm with Surface Light Chain Restriction and Tdt Coexpression Evolved in a MYC-Rearranged Diffuse Large B-Cell Lymphoma: A Dilemma in Classification

Figure 5

Flow cytometry on bone marrow aspirate: a population of monotypic B-cells, expressing CD45, CD10, CD38, and surface kappa light chain restriction. The monotypic B-cells are negative for CD 5 with downregulation of pan B markers (partial CD79 (dim), loss of CD19 and CD20).
