Primary cutaneous T-cell-rich B-cell lymphoma.
A 61-year-old man presented with a skin tumour in the right axilla of 2 months' duration. An excision biopsy revealed a malignant lymphoma, of diffuse mixed small and large cell type, morphologically suggestive of T-cell lymphoma, but shown to be a T-cell-rich B-cell lymphoma by subsequent immunohistochemical staining. A review of the literature revealed 47 cases of T-cell-rich B-cell lymphoma with descriptions of primary sites, 35 nodal and 12 extranodal, of which only one was a cutaneous primary.
