The results showed that fever and generalized lymphadenopathy were the first appeared and more commonly occurred clinical manifestations. 12 of 19 cases(63. 2%) which had been followed up died of relapse and progression of the disease.Pathologically, focus and/ or sheet- like proliferation of tumorous lymphoid cells, including pale cells and convoluted cells with obliteration of involved lymph nodes was the histologic feature of the disease. Within these 24 cases of IBL-like T-cell lymphomas diagnosed by morphologic criteria, tumor cells of 20 cases gave positive reaction to T-cellmarkers and the remaining 4 cases were reactive to B cell markers as well. Immunoblasts and plasma cells showed polyclonal proliferation. Immunotypic analysis showed that rearrangement of T-cell receptor beta chain was detected in 1 case of the disease. Pathologic diagnosis of the disease and relationships between biologic behaviors and the prognosis were also discussed.展开更多
