Broncholithiasis Who Underwent Lung Resection：Report of a Case

はじめに　気管支結石症は気管支内に結石が発生する疾患で大喀血の原因となるが，報告数は少なくまれな疾患である．結核が原因となることが多く，近年は減少傾向である．気管支結石症による繰り返す喀血のため，肺切除術を施行した1例を経験したので報告する．

A 42-year-old woman presented with bloody sputum. Her chest computed tomography （CT） scan revealed a 21 mm nodular shadow with 5 mm of calcification in the right S8 area. She was referred to our department for further examination and treatment, and underwent thoracoscopic partial resection of the right lower lobe. Pathological examination identified a 5 mm stone surrounded by lymphoid follicle formation and plasma cell infiltration. The diagnosis was broncholithiasis associated with an Aspergillus infection. Broncholithiasis is a relatively rare disease, and a review of the literature is provided.
