A rare tumor cause of ileus: primary intestinal lymphoma

Abstract

Primary intestinal lymphomas (PBL) are rare tumors and extranodal lymphomas. They constitute 1% of malignant tumors of the gastrointestinal (GI) system. Colorectal lymphomas constitute 10-20% of all GI lymphomas and are most commonly located in the cecum. For a case to have PBL, in addition to the dominant GI symptoms, the clinical and radiological absence of pathological lymph nodes located outside the intestine, mediastinum, abdomen, or peripheral is required. In addition, there should be no findings in favor of lymphoma in the liver, spleen, and bone marrow. In this report, a 59-year-old female patient who was admitted to the emergency department with a clinical diagnosis of obstructive ileus while being investigated for abdominal pain lasting for 1 month, was operated on because of the development of an acute abdomen and an obstructive mass as a result of imaging, and was reported as having diffuse large cell lymphoma as a result of postoperative pathology, lastly as a result of the examinations performed, primary intestinal lymphoma was detected, and the diagnosis of the disease is presented. Since the first presentation of PBL may be intestinal obstruction and/or perforation due to delayed diagnosis, PBL should be kept in mind in patients presenting with obstructive ileus in emergency admissions.
