[Surgical treatment for patients with pulmonary sclerosing hemangioma]

Sclerosing hemangioma of the lung, a rare disease, is a low grade malignancy possibly originating from type II pneumocytes or Clara cells. We report the clinical characteristics of 8 patients who underwent surgical resection for sclerosing hemangioma between 2005 and 2010 in our hospital. All cases were female, and the average age was 50 (range: 28-83) years old. The median tumor doubling time was 965 days, suggesting they were slowly growing tumors. In the present cases, five patients had another lung disease: lung cancer in two, metastatic lung tumor in one and atypical adenomatous hyperplasia in two patients. Intraoperative frozen section examinations were performed in seven cases. Five patients were diagnosed correctly, but two patients were diagnosed with adenocarcinoma and organizing pneumonia. As a clinical characteristics, sclerosing hemangioma in the present study showed well-demarcated and slow-growing tumor. The postoperative clinical courses of all cases were uneventful, and no findings of recurrence distant metastasis, lymph node metastasis and local recurrence after surgery were observed in any of the patients.
