ABSTRACT
Both glandular papilloma (GP) and sclerosing pneumocytoma (SP) are rare tumors in the lung. We herein report an extremely rare case of coexistence of these two uncommon tumors. The patient was a 40-year-old Japanese woman with no chief complaint. A solitary nodule of the lung was detected using chest computed tomography. The transbronchial biopsy revealed that the tumor histologically corresponded to GP. The patient subsequently underwent partial resection of the right upper lobe. Histological examination of the resected specimens further revealed that the mass contained two different and independent elements and displayed typically histological features of GP and SP. Molecular analysis further revealed the presence of BRAF V600E and AKT1 E17K mutations in GP, whereas only AKT1 mutation was detected in SP. To our knowledge, this is the first case of coexistence of GP and SP in the bronchiole harboring common AKT1 mutation and different BRAF V600E mutational status.
