Primary gastric lymphoma and pseudolymphoma.
Eighteen patients with primary gastric lymphomas and two with pseudolymphomas treated at the University of Louisville affiliated hospitals were analyzed in order to develop a more precise understanding of these rare diseases. Abdominal pain and weight loss were the most common initial symptoms. Only one patient presented with an abdominal mass. Upper GI series were helpful but failed to show a definite abnormality in two of 18 cases. Endoscopic examinations in all 18 were compatible with malignancy on gross finding, but six out of 15 endoscopic biopsies were not conclusive. All four cases, which proved fatal in less than two years, showed serosal invasion and diffuse histological pattern. On the basis of our analysis, we suggest that in patients with abdominal pain and weight loss of more than two months duration an aggressive course of evaluation should include upper gastrointestinal x ray and repeated endoscopic biopsy. If symptoms persist, laparotomy and biopsy may be warranted even if endoscopic biopsy shows no neoplasm. Curative surgery is the treatment of choice, but radiation therapy should be added in patients with serosal involvement. Very careful histological assessment of pseudolymphomas is necessary, because they may contain malignant lymphoma.
