The BCR-PDGFRA fusion is a very rare event. To date, only eight cases of hematolymphoid neoplasms with the BCR-PDGFRA fusion gene have been reported. All cases except one had eosinophilia. We present the first case of T acute lymphoblastic leukemia with a t(4;22)(q12;q11.2) involving the BCR and PDGFRA genes, without associated eosinophilia. Radiology showed splenomegaly and extensive lymph node involvement. The patient rapidly achieved complete remission with treatment protocol for Philadelphia chromosome-negative acute lymphoblastic leukemia.
