Multiple Synchronous Mucosa-Associated Lymphoid Lymphomas Involving in the Stomach, Duodenum, Ileum, and Sigmoid

Descripción
Sumario:Gastric MALToma is an extra-nodal marginal-type B-cell lymphoma. MALToma may occur secondary to chronic inflammation and autoimmunity. The most common gastrointestinal (GI) site of MALToma is the stomach, with approximately 50% of lesions occurring there. Synchronous upper and lower GI MALTomas rarely occur, with few cases reported. We present the case of a 67-year-old patient who presented asymptomatic and was found to have synchronous multifocal upper and lower GI MALTomas in the stomach, duodenum, terminal ileum, and sigmoid, which did not respond to H. Pylori eradication therapy.
