A 65-year-old woman visited a family doctor for hemoptysis. She was suspected to have bleeding due to an infectious pulmonary cyst and was treated with antibiotic agents. She developed hemoptysis again three months later. Therefore, she was treated with hemostatic and antibiotic agents. However, because the cause of hemoptysis was unknown, she was referred to our department. Video-assisted thoracoscopic S6 segmentectomy of the left lung was performed. Pathologically, was noted a cavity lesion accompanied by pulmonary laceration. Although hemoptysis due to pulmonary cysts can be caused by various factors, the hemoptysis was suspected to occur in a pulmonary cyst, but pathologically it was determined as due to a pulmonary laceration. However, the cause of the pulmonary laceration remains unclear. Pathological diagnosis of this lesion was difficult.
