title: MALT Lymphoma of Caecum Presenting as Acute Intestinal Obstruction: A Case Report.
abstract: Mucosa-associated lymphoid tissue lymphomas (MALT lymphoma) are well known, but colonic MALT lymphomas are extremely rare. We report the first case of mucosa-associated lymphoid tissue (MALT) lymphoma in the cecum from India presenting as acute intestinal obstruction with mass in right iliac fossa showing diffuse thickening of ascending colon and caecum with obliterated lumen along with nodular mass on CECT scan of abdomen. On video colonoscopy, circumferential ulcerated growth was seen at cecum, and the rest of the colon was normal. Multiple biopsies from growth suggested malignancy. Right hemicolectomy was performed. The histopathology of resected specimen demonstrated low-grade B-cell MALT lymphoma of the cecum, and the depth of invasion was up to the muscular layer. This was confirmed by immunohistochemistry.
