title: Primary bone lymphomas-Clinical cases and review of literature.
abstract: Primary bone lymphoma (PBL) is an uncommon clinical entity and a rare presentation of non-Hodgkin's lymphoma. PBL accounts for less than 5% of malignant bone tumors, 4-5% of extra nodal lymphoma and less than 1% of all non-Hodgkin's lymphoma. Diffuse large-B-cell lymphoma (DLBCL) accounts for the majority of cases of PBL. The incidence of PBL is so rare that many of its aspects remain unknown. A number of studies have been reported from western countries but only a few reports are available from Asia. Out of 20,000 bone lesions received in our department over 5 years, only 5 cases were primary bone lymphoma; all of which were DLBCL. We report our experience on PBLs with main emphasis on two unusual presentations of this rare tumor.
