Non-Hodgkin's lymphoma relapse as Burkitt lymphoma leading to ileocecal intussusception in an adult patient-a case report.

Burkitt Lymphoma, an aggressive form of non-Hodgkin's lymphoma, is a rare cause of ileocolic intussusception in adult patients. We present the case of a 17-year-old male patient, with a history of non-Hodgkin's lymphoma in childhood, presenting with acute abdominal pain, vomiting, and diarrhea. CT and colonoscopy findings revealed ileocolic intussusception with a large ileocecal mass, leading to a diagnosis of Burkitt Lymphoma after histopathological and immunohistochemical examination. This case highlights the rarity of Burkitt Lymphoma causing intussusception in adults, a condition more commonly seen in children. The case also underscores the importance of considering Burkitt Lymphoma in patients with a history of non-Hodgkin's lymphoma presenting with acute abdominal symptoms. He was successfully treated with surgery without any complications. On follow-ups, he is doing well.
