A Rare Cause of Acute Abdomen; Burkitt's Lymphoma

Introduction: Burkitt lymphoma, one of the non-Hodgkin's lymphomas with aggressive behavior, frequently shows extranodal involvement. Case Report: A 10 year-old male patient admitted to the emergency department with abdominal pain. He had significant right lower quadrant tenderness, but abdominal guarding and rebound tenderness signs were not clear. On admission, patient's white blood cell count was in normal range. Abdominal ultrasonography and intravenous contrast-enhanced abdominal computed tomography revealed periintestinal fluid around the cecum and pathological lymph nodes. The patient was hospitalized to the general surgery clinic for follow-up and treatment. Because of the patient's white blood cell count increased to 18200/ mu L (neutrophils 89.7%) in follow-up he was operated urgently. A mass lesion which is localized approximately 4-5 cm proximal to the cecum and filling the lumen was detected. It had soft consistency on palpation and obstructed the lumen almost complete. The lesion was reported as Burkitt's lymphoma. Conclusion: It is difficult to diagnose intestinal lymphoma with routine radiological methods. An alternative diagnosis should be kept in mind in the patients who admitted to the emergency department with acute abdomen.
