Endemic Burkitt’s Lymphoma is seen in the malaria belt of sub-Saharan Africa around the equatorial region. It affects mainly young children (4 to 10 years old) with 2:1 male:female ratio. The sites commonly involved are jaw, facial bones, and the orbit. Most cases are positive for Epstein-Barr virus (EBV). "Large facial Burkitt's Lymphoma" by Mike Blyth - Own work.
