title: Intussusception as clinical presentation of primary non-Hodgkin lymphoma of the colon in a HIV-patient.
abstract: Intestinal intussusception rarely occurs in the adult population and accounts only for 1% to 5% of all the causes of intestinal obstruction. This complication is more frequent in the small bowel and can be due to different aetiologies, including inflammatory, infectious or neoplastic diseases. Malignancies account for 50% to 60% of all cases of colon invagination. The gastrointestinal (GI) tract is the most common site for extra-nodal non-Hodgkin lymphomas (NHL), representing 5% to 20% of all the cases. However, primary NHL of the GI tract is a very infrequent clinic-pathological entity and accounts only for 1% to 4% of all the neoplasms of the GI tract. Primary NHL of the colon is a rare disease and it comprises only 0.2% to 1.2% of all colonic malignancies. Here we describe a case of an AIDS adult patient who developed an intussusception secondary to a primary large B cell lymphoma of the transverse colon. English and Spanish literature was reviewed.
