DX: Gastric Mucosa-Associated Lymphoid Tissue (MALToma)

This case was particular because of it's presentation. One could expect from seeing images that arises from hepatic or gastric tissue as it seems that there is no boundary between them. Here is the spot image:

History of food intolerance, thickened gastric wall that seems uncollapsed, are clue to diagnosis. If an hepatic mass extends and infiltrates to stomach ussualy it obliterates its lumen.

Endoscopy biopsy proved to be a lymphoma of gastric origin, a MALToma.

MALTomas are extranodal manifestations of marginal-zone lymphomas. Most MALTomas are a low grade, although a minority either manifest initially as intermediate-grade non-Hodgkin lymphoma (NHL) or evolve from the low-grade form. 

Malignancies that occur in mucosa-associated lymphoid tissue (MALT) are called MALT lymphomas or MALTomas. Most of the MALTomas occur in the stomach, and roughly 70% of gastric MALTomas are associated with H. pylori infection.
