Abstract

Primary extranodal Natural Killer / T cell lymphoma (NKTL) on gastrointestinal tract is an uncommon and aggressive neoplasm. We present the case of a 51-year-old immunocompetent patient with a 2-month history of abdominal pain. Colonoscopy findings showed ileal ulcerations, so studies were carried out to rule out Crohn’s disease and intestinal tuberculosis. Later, he developed intestinal obstruction. Exploratory laparotomy found a nodal conglomerate in the mesentery. Anatomical pathology confirmed the diagnosis of primary NKTL on the ileum. Chemotherapy was initiated but the patient asked for voluntary discharge because of his precarious condition. Two months after discharge the patient died. This lymphoma has been reported mainly in Asia and is possibly the first case in Peru. It has a dismal prognosis with overall survival of 8 months. Therefore, it is necessary to get an early diagnosis and begin therapy in a timely manner.
