A female patient, 69 years old, was hospitalized because of a 2-year history of recurrent hemoptyses resulting in severe anemia. X-ray examination of the chest showed a mass lesion in the right lower lung field, which had grown over the preceding 2 years. Bronchographic, arteriographic and CT examinations excluded the possibilities of bronchiectasis, pulmonary A-V fistula or sequestration. Histological examination following right lower lobectomy revealed no evidence of neoplasms or tuberculosis, fungal and parasitic infections but showed a predominant mononuclear cell infiltration and abundant small vessels in the affected small bronchi, and peribronchiolar and adjacent alveolar regions. To our knowledge, no case with chronic bronchopneumonia accompanied by such massive hemoptyses, as seen in this case, has been reported to date.
