Abstract

Mucosa-associated lymphoid tissue (MALT) lymphoma is the most common type of extra-nodal non-Hodgkin lymphoma, which mostly involves the stomach. The clinical suspicion and diagnosis are often challenging because of the lack of specific symptoms and conventional endoscopic findings. Three magnifying endoscopic signs of the gastric mucosa have been described as highly specific to the diagnosis of MALT lymphoma, such as (i) tree-like appearance of the microvessels; (ii) non-structural area; and (iii) ballooning crypt pattern. We report the case of a middle-aged woman in which these signs appeared chronologically over a period of 2 years, showing the association of the sequence of the endoscopic findings and the final histological diagnosis of gastric MALT lymphoma.
