RESUMO
Adult intussusception is rare. Here, we describe a case of an AIDS adult patient who developed an ileocolic intussusception secondary to a large B cell lymphoma of the cecum. Surgical findings included the ileon free of the tumor and invaginated within the cecum with infiltrating neoplasm. Surgical treatment included the resection of the right hemicolon because of the tumor, located in the cecum, causing intussusception. The English and Spanish literature is reviewed.

A retrospective study was conducted of extranodal oral Non-Hodgkin's Lymphomas diagnosed at the Surgical Pathology Laboratory of the School of Dentistry at Buenos Aires University, Argentina, between 1985 and 2004. The 40 cases found represent 0.2% of the oral biopsies diagnosed during that time and 4.6% of malignant neoplasias. Overall mean age of patients was 49.4 years, and frequency was greater in males. 80% affected soft tissues. Prevalent location was gingival, followed by palate. Intraosseous cases were more frequent in mandible (75%) than in upper maxilla. 100% of the cases were phenotype B, with a higher frequency of high-grade aggressiveness. The most common histological type was Diffuse Large Cell Lymphoma. 60% of the Plasmablastic Lymphomas in the series came from HIV+ patients. Evolution time prior to consultation was 1 to 3 months in 57.7% of the cases.

Non-Hodgkin's lymphoma of B-cell type is the second most common neoplasm after Kaposi's sarcoma, among patients with human immunodeficiency virus infection. Most non-Hodgkin's lymphoma cases that are associated with acquired immunodeficiency syndrome involve extranodal sites, especially the digestive tract and the central nervous system. We report a case of primary lymphoma of the duodenum in a patient with AIDS. Upper gastrointestinal endoscopy revealed pseudopolypoid masses found in the second portion of the duodenum. A complete diagnostic study including histological, immunohistochemical and virological analyses showed high-grade B-cell Burkitt's lymphoma. The Epstein-Barr virus genome was detected in biopsies by immunohistochemical and in situ hybridization.
