Abstract
A 57-year-old woman was referred to the hospital because of abnormal circular shadow in the right middle lung on a chest-ray film at another hospital in July, 1997. A possible malignancy could not be ruled out after close examinations, and an excision of the right middle lower lobe of the lung was carried out. Intraoperative frozen section diagnosis indicated adenocarcinoma, and mediastinal lymph node dissection was added. The definitive diagnosis of sclerosing hemangioma of the lung was made based on the permanent preparation. Immunohistologically, cuboidal cells were positive for surfactant apoprotein A that is an indicator of type II alveolar epithelial cell. Although the true natures of the sclerosing hemangioma are still debatable, a recent view that regards the hemangioma as a benign tumor arising in alveolar epithelial cell has become the most convincing theory. And the immunohistological findings in this case also supported the theory.
