Endobronchial valves– an iatrogenic cause of hemoptysis to be considered at autopsy

An 80-year-old man who presented with hemoptysis died from ischemic heart disease and emphysema with cor pulmonale. He had a past history of ischemic heart disease with previous myocardial infarction, chronic obstructive pulmonary disease with endobronchial valve insertion and squamous cell carcinoma of the lung with lobe resection. On the day of death he had coughed up approximately one tablespoon of blood. While causes of hemoptysis usually include entities such as bronchitis, pneumonia, bronchiectasis, tumors, adjacent aneurysms, inflammatory/infective processes or septic emboli, occasionally there may be an iatrogenic etiology. The present case demonstrates a rare cause of hemoptysis associated with medical treatment - endobronchial valve insertion with surrounding granulation tissue formation and resultant hemorrhage. Hemoptysis in decedents with COPD may, therefore, be due to treatment rather than to underlying inflammatory or neoplastic lesions.
