Case description

Gastroduodenal MALT lymphoma Endoscopy shows large erosion, biopsies were positive to be a maltoma. Mucosa-Associated Lymphatic Tissue (MALT) Lymphoma is a very rare type of Non-Hodgkin’s Lymphoma. MALT tissue is lymphatic tissue that is found in the stomach, lungs, thyroid, salivary glands, intestines, and eyes, so it is classified as "extranodal" (out of the nodes) MALToma typically results from a mutation of B-cells in this extranodal tissue. It is an indolent, or slow growing, cancer. MALToma can arise in any organ with MALT tissue. Though the stomach is the affected organ in most cases (2 out of 3), the lungs, thyroid, and eyes can be involved also. This cancer is associated with several diseases and conditions, such as the bacteria Helicobacter pylori, Sjogren Syndrome, Celiac Disease, Chron’s Disease, or Hashimoto Thyroiditis.
