Fetal lung interstitial tumor (FLIT) is a rare pediatric lung tumor with radiological features similar to developmental pulmonary malformations and other congenital lung neoplasms. There are about 17 cases of FLIT reported worldwide till date. We report the first case of FLIT in the Indian literature which was diagnosed in the early postnatal period (at the 21st day of life) by pathological examination. The tumor exhibited a novel focal micropapillary architecture, in addition to the previously described microscopic features. We discuss the pathogenesis and differential diagnoses of FLIT and review the literature.
