We report a 71-year-old male who was referred to our department because of an abnormal chest shadow. Chest computed tomography (CT) revealed a tumor shadow with a diameter of 7.2 cm in the upper right lobe, for which bronchoscopy was performed. Based on the findings of transbronchial lung biopsy, the tumor was diagnosed as a non-small cell carcinoma (grade cT4aN0M0 stage IIIA). We performed upper right lobectomy and lymph node dissection (ND 2a-2) using video-assisted thoracic surgery. Pathological examination revealed a high-grade fetal lung adenocarcinoma (H-FLAC). The pathological stage was evaluated as T4aN0M0 stage IIIA. The patient was treated with adjuvant chemotherapy (cisplatin+pemetrexed) and discharged 8 days after the surgery. He is now alive with no evidence of recurrence 3 months after the surgery. H-FLAC is a very rare lung adenocarcinoma with very few reported cases in the literature.
