Summary A 76‐year‐old man presented with a 3‐month history of a cutaneous nodute on the right thigh. The tumour was composed of CD3+, large atypical cells, and CD20+, small normal‐appearing cells. Flow cytometry showed that CD20+ cells outnumbered CD3+ cells. By Southern blot hybridization analyses, the malignant cells were shown to be of T‐cell origin, because of the presence of rearranged bands for the β chain of the T‐cell receptor, but not for the immunoglobulin heavy chain. This case represents a T‐cell lymphoma intermingled with a large number of non‐neoplastic B cells.
