Methods: Data from 112 MCL cases were collected, and immunohistochemical assay was conducted. Fluorescence in situ hybridization (FISH) detected a break in the CCND 1 gene. The t-test was used in the statistical analysis. Results: All tumor cells in the 112 cases expressed B cell-related antigen, including 1 blastoid subtype and 1 polymorphic subtype. Among all cases, 106 expressed CD5 and 104 expressed cyclin D1. A break in the CCND1 gene was not found in 3 cases with CDS-MCL. IgH/CCND 1 polyploid was observed in 2 classic cases. Conclusion: MCL is a type of special immunophenotypic B-cell lymphoma, The prognoses ofblastoid and polymorphic subtypes are poor. Special subtypes should be classified during diagnosis.展开更多
