Fetal Lung Interstitial Tumor (FLIT): A case series

Background: Fetal Lung Interstitial Tumor (FLIT) is a rare benign lung tumor. There have been 18 cases of FLIT described in the literature. FLIT is characterized by a region of arrested lung development and must be differentiated from other congenital lung lesions with poorer prognoses. Case Presentation: We report the first two known cases of FLIT in Australia and New Zealand. In both cases, the patients developed respiratory distress at birth requiring intubation. Imaging revealed solid lesions and echocardiography demonstrated pulmonary hypertension. The patients underwent surgical resection without any complications or recurrence. Conclusion: FLIT is a rare benign congenital lung tumor that can be adequately managed with surgical resection.
