Burkitt`s lymphoma is a distinct pathologic entity characterized by a diffuse proliferation of small, noncleaved cells of B-lymphocytes origin. It was first reported as "jaw sarcoma" in East African children and described as endemic in tropical Africa. Burkitt`s lymphoma usually occurs in youth and children, but it is very rare in an adult gastrointestinal tract of an adult. We recently experienced an unusual case of Burkitt`s lymphoma in a 69-year-old male with lower abdominal pain and a mass. A colonoscopy and abdominal CT scan detected an ileocecal fungating mass with intussusception, and the histologic examination of the resected and biopsy specimens showed infiltration of medium-sized lymphoblasts with characteristic "starry sky" machrophages. So we report it with a brief review of literatures.
