Burkitt Lymphoma Presenting as Acute Pancreatitis: Report of 3 Cases and Review of the Literature.

Acute pancreatitis is a rare presentation in Burkitt lymphoma (BL) and may lead to delayed medical or unnecessary surgical treatment. Three cases of BL presenting as acute pancreatitis in the authors' institutions were described. Similar cases reported in the medical literature were collected and described along with the authors' cases. There were 12 cases described in the medical literature and hence a total of 15 cases of BL presenting as acute pancreatitis. Fourteen cases were the first diagnosis, and the other presented at lymphoma relapse. Twelve cases occurred in children under 15 years. Twelve patients had extrapancreatic disease. Three children were treated with surgery before diagnosis. Two patients died. Six of the remaining had adequate follow-up and were surviving in remission 8 months to 16 years after diagnosis. Lymphoma should be included in the differential diagnosis of acute pancreatitis in children. Acute pancreatitis in combination with malignant infiltration on imaging is highly suggestive of BL, especially in the jaundiced child.
