Epstein‐Barr virus (EBV)‐related lymphoproliferative disorders are relatively common in Iraqi children. Burkitt lymphoma (BL) accounted for 40% of lymphoma cases. The mean age of 125 BL cases was 5.9 ± 3.1 years, and the male‐to‐female ratio was 3.6:1. Clinical presentation was abdominal in 66% and head and neck in 34%. Bone marrow involvement was higher ( P < 0.001) in children with head and neck disease. Tumor cells had MYC translocation (96%) and were CD20 + /CD10 + /MYC + /BCL2 − . MUM1/IRF4 staining was expressed by a fraction of tumor cells in 19 of 125 cases (15%) and was more frequent ( P < 0.007) in head and neck disease (12/42; 29%). EBV‐encoded RNA was positive in 100 of 125 (80%) BL cases.
