Primary gastric lymphoma (PGL) is the most common extranodal non-Hodgkin lymphoma and the second most common gastric malignancy following adenocarcinoma.1 Epidemiological studies conducted in early 1990s supported the association between PGL and Helicobacter pylori (H. pylori) infection.2, 3 It is also believed that microbial genetic factors such as cytotoxin-associated antigen A (cag A) in addition to host genetic or environmental elements would affect the development of PGL.4 Although it is known that PGL accounts for only 3–5% of malignant gastric tumours,4 this proportion may be varied according to the regional H. pylori prevalence or strains considering the report from northern Italy where the incidence of PGL was 10 times higher than that in the United Kingdom.
