Abstract:
Objective To investigate the clinicopathological features of primary gastric malignant lymphoma.Methods 32 cases of primary gastric non Hodgkin's malignant lymphoma(NHL)were studied by clinicopathology,immunohistochemistry and ultrastructure.Results 3 cases of NHL arose from fundus of stomach,7 cases from body of stomach,8 cases from gastric angle,and 14 cases from gastric antrum.The paraffin sections of all cases were stained.There were 31 cases(96\^9%)exhibiting B cell phenotype,only 1 case(3\^1%)exhibiting T cell phenotype.11 cases of NHL and 6 cases of undifferentiated carcinoma(UC)in stomach were observed comparatively under electron microscope(EM).The ultrastructural characteristics of NHL were much different from those of UC.Conclusion Most primary gastric malignant lymphoma are B cell lymphomas.Immunohistochemistry and ultrastuctural observation are much helpful in the diagnosis and differential diagnosis between NHL and UC.
