    Abstract:
    A 53-year-old woman was admitted for recurrent hemoptysis and cough. The chest radiograph showed an infiltrative shadow in the left upper region. Chest tomogram and CT scan showed a small calcification and consolidation in the left upper lobe. Fiberoptic bronchoscopy revealed fresh hemorrhage from the left upper bronchus but no broncholith or bleeding point were detected. Since the symptoms had disappeared by 10 days after admission, the patient was discharged and followed up as an outpatient. Three weeks later, she spontaneously expectorated a stone 3 mm in maximum diameter, with an irregular surface. Analysis revealed that the stone's composition was 56% of calcium phosphate and 44% of calcium carbonate. Hemoptysis seemed to have been caused by the broncholith, which had originated as a calcification of a peribronchial lymph node that subsequently eroded its way into the airway. After lithoptysis, no recurrence has been observed.
