Pediatric B‐Cell Lymphoma With Lymphoblastic Morphology, TdT Expression, MYC Rearrangement, and Features Overlapping With Burkitt Lymphoma

Burkitt lymphoma (BL) and B‐lymphoblastic lymphoma are subtypes of pediatric non‐Hodgkin lymphoma with different presenting features, treatment, and outcomes. This case report documents a 5‐year‐old female who presented with B‐cell lymphoma with lymphoblastic morphology, terminal deoxynucleotidyl transferase expression, MYC rearrangement, and features overlapping with BL. Genomic microarray analysis identified a gain on the long arm of chromosome 1 without other definitive changes. She was treated according to a BL protocol and remains in remission 16‐months after initial diagnosis.
