Primary gastrointestinal malignant lymphoma

Objective To investigate the clinical manifestation,pathological feature of endoscope and healing methods in the primary gastrointestinal malignant lymphoma(PGIML).Methods Retrospectively summarized and analyzed the clinical and endoscope data of 21 patients with PGIML confirmed by pathology.Results In the 21 patients,the major symptoms were abdominal pain,anorexia,abdominal distention and hematochezia.The common locus was stomach and endoscope manifestations were intumescent,ulcerative and diffusely infiltrative lesion,respectively.Ten patients with PGIML were diagnosed by endoscope biopsy.Twenty-one patients were all certified non Hodgkin lymphoma,including 10 cases of mucosa associated lymphoid tissue(MALT) lymphoma.Conclusion In the PGIML patients,the most common clinical symptom is abdominal pain,and the most common location is stomach.There are no significant differences among ulcer,tumor and PGIML under endoscope.Extra nodal marginal zone B-cell lymphoma of MALT is the main histopathologic feature.The further ultrasound endoscopy binding relative pathology can contribute to eventual diagnosis.The prognosis of PGIML is better than the other tumors of gastrointestine.
