Malignant lymphomas in Beijing.
We report on 1,082 cases of malignant lymphomas from the files of the Department of Pathology, Chinese PLA General Hospital, Beijing. We found non-Hodgkin's lymphomas (NHL) in 980 cases (91%) and Hodgkin's disease (HD) in the remaining 102 cases (9%). Among the NHL, the diffuse type was seen in 955 cases (97.4%) and the follicular type in 25 cases (2.6%). Among the diffuse NHL, the pleomorphic type was most frequently found (263 cases or 26.8%), followed in frequency by the mixed small and large cell (163 cases or 16.6%). The large-cell cleaved and noncleaved immunoblastic was found in 139 cases (14.2%), small cleaved cell in 132 cases (13.5%), lymphoblastic convoluted and nonconvoluted in 72 cases (7.3%), the small lymphocytic type in 128 cases (13.1%), plasmacytoid type in 40 cases (4.1%), and Burkitt type in 18 cases (1.8%). Using immunohistocytochemistry, we found T-cell lymphoma in 53% and B-cell lymphoma in 47% of cases. The distinctive differences of malignant lymphomas types between China and Western countries suggest the possibility of a relationship to environmental factors.
