Abstract

The fusion product of FIP1‑like‑1 (FIP1L1) and platelet‑derived growth factor receptor α (PDGFRA) gene rearrangement is a tyrosine kinase oncoprotein sensitive to imatinib. This gene rearrangement characterizes a novel clinico‑biological class of myeloid and lymphoid neoplasms with eosinophilia and PDGFRA abnormalities. The DEK proto‑oncogene (DEK) and nucleoporin 214 (NUP214) rearrangement is rare in patients with acute myeloid leukemia (AML); therefore, the coexistence of DEK‑NUP214 and FIP1L1‑PDGFRA rearrangements in patients with AML is extremely rare. The present study presents a rare relapse case of a patient with AML with DEK‑NUP214 and FIP1L1‑PDGFRA rearrangements, without marked eosinophilia in the peripheral blood or bone marrow. Low‑dose imatinib monotherapy without intensive chemotherapy was used to achieve complete hematological remission.
