Figure 5: TCRBCL: A 61-year-old man presented with fever, 2 × 3 cm right upper cervical lymphadenopathy and splenomegaly. FNA cytodiagnosis was TCRBCL. ICC: tumor cells were CD20+, CD3–, CD30–, and CD15–, and mature lymphocytes were CD3+. Histopathological diagnosis was THRLBCL. (a) A mixture of large atypical lymphoid cells and mature lymphocytes (MGG × 400). (b) Atypical lymphoid cells have abundant bluish cytoplasm (MGG × 1000). (c) The background also shows many benign histiocytes (Papanicolaou × 400). (d) There were scattered binucleated RS-like cells with prominent nucleoli (Pap × 1000). (e) Large atypical lymphoid cells were positive for CD20 (×400). (f) The background mature lymphocytes were positive for CD3
