Very late relapse of Burkitt's lymphoma in an EBV-negative patient after 20 years of complete remission.

Burkitt's lymphoma (BL) is an aggressive B-cell lymphoma that occurs in children and adults. It is a chemosensitive lymphoma with very exceptional cases of late relapse. We report the case of a 32-year-old male, originally from a nonendemic area for BL, who was successfully treated for abdominal BL 20 years ago.
