Primary @entity1893 's @entity706 (PLB) is a @entity395 representing less than 1% of all @entity1893 and has rarely been reported in Taiwan. A retrospective clinicopathological study was performed according to the 2002 World Health Organization criteria and identified 14 cases during a 13-year period in 2 medical centers in southern Taiwan. There was male predominance (M:F = 6:1) with a median age of 42 and @entity158 (6 @entity1 , 43%) as the most common symptom. Half of the @entity1 had monostotic and the other half @entity75 . Axial skeletons (10 cases, 71%) were the most frequent sites of involvement. The staging results were stage I (9 @entity1 , 64%), stage II (2, 14%) and stage IV (3, 21%). Eight cases (57%) were of B-cell phenotype and the remaining 6 (43%), T-cell. Histologically, 7 (50%) were diffuse large @entity1892 (DLBCLs) and 5 (36%) anaplastic large cell lymphomas. Seven @entity1 received chemotherapy and radiotherapy; 4 chemotherapy and 3 radiotherapy alone. Of the 11 @entity1 with follow-up information, 6 (55%) died of disease within 1 year including 5 with @entity784 , while all the 5 @entity1 surviving over 1 year were of B-cell phenotype. The overall 1-year survival rate was 45%. The survival of @entity1892 was significantly better than T-cell @entity5 (p = 0.016, log-rank test). In summary, this study reported the largest series of PBL in Taiwan and confirmed that the majority was DLBCL and @entity1892 had more favorable prognosis. As compared to the Western series, the cases showed a striking male predominance, higher percentage of axial skeleton involvement, higher relative frequency of @entity5 and poorer prognosis.
