Fetal lung interstitial tumor (FLIT), which is characterized by immature interstitial cells resembling the fetal lung parenchyma of 20 to 24 weeks of gestation, is a rare respiratory neoplasm. This study presents the first reported FLIT in Korea. It also aims to refine the diagnostic method of FLIT and increase the accuracy of prognostic assessment by using next-generation sequencing to check for anaplastic lymphoma receptor tyrosine kinase (anaplastic lymphoma kinase) gene rearrangement. Although the initial prognosis for FLIT has been promising since its first report in 2010, certain pathological features are associated with poorer outcomes. Therefore, achieving an accurate diagnosis of FLIT is crucial for avoiding unnecessary treatments beyond surgical resection.
胎儿肺间质瘤(FLIT)是一种罕见的呼吸肿瘤,其特征是存在类似于妊娠20至24周胎儿肺实质的未成熟间质细胞。本研究报告了韩国首例FLIT病例。该研究还旨在完善FLIT的诊断方法,并通过使用下一代测序检查间变性淋巴瘤受体酪氨酸激酶(间变性淋巴瘤激酶)基因重排,提高预后评估的准确性。尽管自2010年首次报告以来,FLIT的初始预后一直很乐观,但某些病理特征与较差的预后相关。因此,准确诊断FLIT对于避免手术切除以外的不必要治疗至关重要。
