Pulmonary sclerosing hemangioma with pleural dissemination: Report of a case

Abstract

Pulmonary sclerosing hemangioma is relatively rare and is usually considered a benign tumor. There have been no reports of pulmonary sclerosing hemangioma with pleural dissemination. This report presents an extremely rare case of pulmonary sclerosing hemangioma with pulmonary dissemination. A 57-year-old woman was found to have an abnormal shadow in the right lower lung field on chest X-ray. Chest computed tomography (CT) indicated a 2.5-cm mass in the right lower lobe. A bronchoscopic biopsy failed to identify malignant cells, which led to the patient undergoing an excisional lung biopsy. Intraoperative findings showed a tumor in the right lower lobe with multiple small nodules in the pleura. The pathological findings revealed that the tumor was sclerosing hemangioma with pleural dissemination. Annual follow-up CT showed irregular pleural thickness, which suggested progressive dissemination 3 years after the operation. Although pulmonary sclerosing hemangioma is regarded as a benign tumor, the potential for malignancy may be a consideration in this setting.
