Аннотация
We report a case of myeloid neoplasm with the abnormality of PDGFRB gene secondary interstitial pneumonia. A 66-year-old male complained dry cough and shortness of breath after regular activities. Two years ago, high-resolution computerized tomography (HRCT) showed interstitial lung diseases, and no clear etiology was found. At that time, the diagnosis was idiopathic pulmonary fibrosis. In the period of hospitalization, the interstitial lung disease was significantly advanced, and the peripheral blood eosinophil was significantly increased. ETV6-PDGFRB fusion genes was positive detected by FISH. Myeloid neoplasm with the abnormality of PDGFRB gene was diagnosed. The patient was treated with the tyrosine kinase inhibitor-imatinib mesylate which is the first choice for this disease currently.Myeloid neoplasm with the abnormality of PDGFRB gene is a rare hematologic tumor characterized by myeloid dysplasia, eosinophilia, and PDGFR gene rearrangement. Most of this tumor occurs in male, often with splenomegaly, and a few have damages in liver, skin, heart, and other organ tissues.
