AIM:To explore and discuss the clinicopathologiccharacteristics of mucosa-associated lymphoid tissue (MALT)lymphoma in gastroscopic biopsy specimen.METHODS:A retrospective study of 26 cases of lymphomadiagnosed by gastroscopic biopsy during 1999 to 2001 fromgastroscopy files of Xijing Hospital was made.The diagnosticcriteria were adopted according to the new classification ofnon-Hodgkin’s lymphoma.RESULTS:Twenty-six cases of primary gastric lymphomaconsisting of 15 men and 11 women,aged between 23 to76 years were recruited from 6 225 cases who receivedgastroscopy.All of them were diagnosed by both endoscopicfindings and histological examinations.Histologically,23cases were MALToma (low grade) and 3 cases lymphoblasticlymphoma (high grade).Immunohistochemically,all caseswere CD20 positive,while CK and EMA were negative.CONCLUSION:The majority of the cases of primary low-grade gastric lymphoma have morphologic and clinicalfeatures that justify their inclusion in the category of low-grade lymphoma of mucosa associated lymphoid tissue.
