[Regression of gastric MALT lymphoma after eradication of Helicobacter pylori infection followed by endoscopic ultrasound].

The authors report a case of a 42 year-old female patient, who was admitted with epigastric pain and weight loss to our department. Upper gastrointestinal endoscopy two ulcerated lesions revealed in the stomach at the corpus-antrum border. Histologically the lesion proved to be a low grade, malignant B cell MALT lymphoma. Coexistent Helicobacter pylori infection was detected with modified Giemsa staining. Endoscopic ultrasonography was performed to determine the depth of tumorous infiltration of the gastric wall: the tumor was confined to the mucosa and submucosa. No regional lymph node was observed. As a result of successful Helicobacter pylori eradication the regression of MALT lymphoma occurred. The follow-up examinations showed the regression of the tumour and the patient became asymptomatic. A control ultrasonographic examinations demonstrated the normal five layers structure of the gastric wall without any alteration. In our patient Helicobacter pylori eradication was an effective therapy for gastric MALT lymphoma as well. Our results similar as are published in the literature. Endoscopic ultrasonography is very useful in the assessment of the tumours involvement of the gastric wall. In the proper follow-up examinations of the patient endoscopy, histology and endoscopic ultrasound together are the methods to apply including Helicobacter pylori control.
