Abstract

BACKGROUND: Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) and mantle cell lymphoma (MCL) both have a common origin arising from mature CD5+ B-lymphocytes. Their distinction is crucial since MCL is a considerably more aggressive disease. Composite lymphoma consisting of CLL/SLL and MCL has been rarely reported. This type of composite lymphoma may be under-diagnosed as the 2 neoplasms have many features in common, both morphologically and immunophenotypically.

CASE REPORT: We report the case of a 57-year-old male patient who presented with a 4-month history of recurrent abdominal pain and distention with hepatosplenomegaly. Peripheral blood showed a high leukocytes count (46.7×10³/uL) with marked lymphocytosis of 35.0×10³/uL, mostly small mature-looking, with some showing nuclear irregularities, with approximately 3% prolymphocytes. Immunophenotyping by flow cytometry and immunohistochemistry revealed 2 immunophenotypically distinct abnormal CD5+monotypic B-cell populations. Fluorescence in situ hybridization (FISH) on peripheral blood demonstrated IGH/CCND1 rearrangement consistent with t(11;14) in 65% of cells analyzed. Accordingly, based on compilation of findings from morphology, flow cytometry, immunohistochemistry, and FISH, A diagnosis of composite lymphoma consisting of MCL; small cell variant and CLL/SLL was concluded.

CONCLUSIONS: We describe a case of composite lymphoma of MCL (small cell variant) and CLL/SLL that emphasizes the crucial role of the multiparametric approach, including vigilant cyto-histopathologic examination, immunophenotyping by flow cytometry and immunohistochemistry, as well as genetic testing, to achieve the correct diagnosis.
