Histologic analysis revealed monomorphic infiltration from lymphoblasts, showing scant cytoplasm and irregular nuclei. (A) Diffuse, uniform, small-to-intermediated sized cells (H & E, ×200). (B) Scant cytoplasm, condensed chromatin and inconspicuous nucleoli; mitotically active lymphoma cells (H & E, ×400). (C) Infiltration of the fibro-fatty tissue (H & E, ×200).
