Diffuse large B-cell lymphoma (DLBCL), not otherwise specified

The analysis of a lymph node shows neoplastic B lymphocytes (purple), T lymphocytes (blue), physiological B lymphocytes (brown) and all lymphocytes (green).

In comparison with normal large T cells, neoplastic B cells show markedly increased values of forward scatter (A). Neoplastic B cells express CD19, CD20 and CD10 (B, C); in this image, a monotypic population of neoplastic B cells is characterised by expression of the light chain sLambda (D).
