Abstract
- Splenic lymphoma with villlous lymphocytes (SLVL) is a B cell chronic lymphoproliferative disorder which affects predominantly elderly males. Most patients present with splenomegaly without lymphadenopathy and a lymphocytosis. This report describes a case of SLVL in 66 year old male who complained abdominal discomfort and abdominal mass. The leukocyte count was 47.8x109/L with 89% atypical lymphocytes showing variable amout of moderately basophilic cytoplasm and unevenly distributed or polar cytoplasmic villi. The bone marrow was effaced with these neoplastic lymphocytes. The immunophenotype of the neoplastic B cells was CD19 (+), CD20 (+), CD22 (+), CD11c (+), CD2 (-), CD3 (-), CD5 (-), CD10 (-), CD25 (-) and CD15 (-). The cytogenetic findings exhibited 46,XY,del (3) (q24),del (10) (p12). The spleen was weighted 520g and had nodular infiltrates of neoplastic B cells in the region of the white pulp with minimal red pulp involvement.
