Abstract

We examined 28 cases of primary bone lymphomas (PBL; stage IE) and 26 cases of systemic lymphomas involving the bone (SBL; stage IIE to IV). Two histologic types were prevalent: Diffuse large B-cell lymphomas (DLBCL; 26 PBL and 21 SBL) and CD30+ anaplastic large cell lymphomas (ALCL; 1 PBL and 4 SBL). A mature B phenotype (CD45+, CD20+, CD79a+, CDw75+/-, CD10-/+) was established in the DL-BCL group. Bcl-2 immunoreactivity was demonstrated in 13/37 cases (35%), and bcl-6 immunostaining was observed in 22/32 cases (69%). ALCL showed null/T phenotype (CD3-/+; CD43+/-; CD30+), with ALK-1 expression in 3/3 cases. With use of a FR3A primer, a monoclonal pattern was demonstrated by PCR analysis in 22/41 lymphomas (54%). Bcl-2 translocation was identified in 2/41 cases (5%). This study details the clinical and pathological characteristics of bone lymphomas. Our immunohistochemical and molecular data suggest that most of them are "de novo" DL-BCL and support their follicle center origin.
