Primary gastric lymphoma is a rare malignant tumor that can sometimes present as spontaneous perforation. We present below a case of spontaneous primary gastric lymphoma perforation that was managed in our institution followed by a brief review of the literature and discussion.
A series of primary gastric lymphomas and adenocarcinomas was reviewed to assess the prevalence of lymphocytic gastritis in these conditions. Lymphocytic gastritis was more prevalent in patients with gastric adenocarcinoma (16 of 130 cases; 12.3%) and primary gastric lymphoma (six of 45 cases; 13.7%) than in unselected patients undergoing endoscopy (0.83-2.5%). This suggests that these two disp...
Primary gastric lymphoma, an uncommon gastric tumor caused by infection with Helicobacter pylori, is rarely associated with gastric amyloidosis. Chronic bacterial infection is known to cause amyloidosis. We report a 53-year-old man who had an antral and duodenal mass with narrowing and ulceration on endoscopy and CT scan; endoscopic biopsy revealed gastric amyloidosis. Rapid urease test and ser...
BACKGROUND Primary gastric B-cell lymphomas arise from mucosa-associated lymphatic tissue (MALT) in patients with chronic Helicobacter pylori infection. We investigated whether germline variants in the CDH1 gene, coding for E-cadherin, genetically predispose patients to primary gastric B-cell lymphoma. DESIGN AND METHODS Single marker analyses of the CDH1 gene were conducted in patients with ...
non-hodgkin lymphoma (nhl) is one of the masquerade syndromes of malignant melanoma that can occur with two main patterns of presentations in the eye: metastatic involvement of uveal tract, and primary involvement of retina. we report ophthalmic, imaging and histopathological findings in the first case diagnosed as primary choroidal nhl without central nervous system or systemic involvement. a ...
Immunoproliferative small intestinal disease (originally called Mediterranean lymphoma and subsequently alpha chain disease) is a slowly progressive low grade primary small intestinal B-cell lymphoma characterized by the synthesis of a truncated alpha heavy chain without light chain by the neoplastic cells. The histological features of IPSID and low grade primary gastric B-cell lymphoma are clo...
Clinicopathologic information of gastrointestinal (GI) lymphoma in Southeast Asia is lacking. A retrospective analysis of 120 cases of GI lymphoma in Thailand diagnosed at Siriraj Hospital based on WHO classification was performed. All were non-Hodgkin lymphoma (NHL). The peak age was in the sixth and seventh decades; a slight male preponderance was observed. Sites of involvement included stoma...
Since nasal NK/T cell lymphoma and NK/T cell lymphoma nasal type are rare diseases, gastric involvement has seldom been seen. We report a unique case of a patient with a primary NK/T cell lymphoma nasal type of the stomach with skin involvement. The patient had no history of malignant diseases and was diagnosed with hematemesis and intense bleeding from his gastric primary site. Shortly after t...
