Gastric MALT Lymphoma: A Rarity

Association of Helicobacter pylori (H. Pylori) infection with gastric 'Mucosa Associated Lymphoid Tissue' (MALT) lymphomas (MALTomas) is well established. In this study the frequency and characteristics of gastric MALToma over a period of 18 years was evaluated. During this period 24 patients with gastric MALToma were diagnosed; out of them, 13 (54.2%) had active H. pylori infection. The mean and median age was 49.7 and 53.5 years. The male: female ratio was 17:7. The common presenting complaints were epigastric pain (n=10) and dyspepsia (n=9). Endoscopic findings revealed mild gastric hyperemia (n=16), superficial erosions (n=4) and superficial ulcers (n=4). It was concluded that the prevalence of gastric MALToma was very low in contrast to a high a pylori gastritis in the Pakistani population.
