Reprospective pathologic study of 86 cased of non-Hodgkin's lymphomas, obtaining
from 1973 to 1981i was performed. It was subclassified according to criteria of
Rappaport and was assessed for age, sex, and bites.
The result were obtained as follows :
1) In the 86 patients, 5 had nodular lymphomas and 81 had diffuse lymphomas.
2) The most common subtype is diffuse histiocytic(29.1%), and followed in order by
diffuse poorly differentiated lymphocytic(20.9%), diffuse mixed(18.6%), diffuse
lymphoblastic(12.8%), diffuse well differentiated lymphocrtic(11.6%), nodular mixed(3.4%),
nodular poorly differentiated lymphocytic(1.2%), nodular well differentiated
lymphocytic(1.2%), and diffuse undifferentiated (1.2%).
3) The male to female ratio of the entire group was 4.4 :1.
4) The mean age of the entire group was 35.7 years. The diffused histiocytic is most
old(39.4 years), and the diffuse lymphoblastic is most young(16.5 years).
5) The sites of the lymphomas are cervical lymph node (40.7%), gastro-intestinal tract
(26.7%), inguinal lymph node(11.6%), tonsil(10.5%), skin and subcutaneous tissue(4.6%),
