ABSTRACT
We report here a case of "splenic lymphoma with villous lymphocytes" (SLVL) which exhibited both B- and T-cell phenotypes and genotypes. The patient was a 73-year-old man. Physical examination revealed splenomegaly and lymphadenopathy. The white blood cell count was 55.2 x 10(9)/L with 70.5% atypical lymphocytes, having cytoplasmic villi, characteristic of SLVL. The atypical cells infiltrated both the red and white pulps. Immunological analysis of the peripheral leukocytes showed both B- and T-cell phenotypes (CD5,CD11c,CD19,CD20,HLA-DR, SmIgM and lambda positive). DNA analysis revealed a dual rearrangement of the immunoglobulin heavy chain gene and T-cell receptor beta gene. SLVL has been identified as a B-cell leukemia with a relatively benign clinical course. This case had both B- and T-cell pheno- and genotypes with a progressive course. To the best of our knowledge, no case of SLVL with dual genotypes has ever been reported.
