A case of hairy cell leukemia with CCND1-IGH@ translocation: indolent non-nodal mantle cell lymphoma revisited..     ///    " CCND1-IGH@ translocation is considered pathognomonic of mantle cell lymphoma (MCL), as this distinct chromosomal abnormality has not been reported in any other subtypes of mature B-cell lymphoma. "    ///    This case suggests that CCND1-IGH@ may rarely occur in other mature B-cell neoplasms such as HCL.
