Three cases of sclerosing hemangioma managed differently are described. Thoracic surgeons should raise their awareness of this benign slow-growing tumor in the differential diagnosis of solitary pulmonary nodule. Radiographic evidence of expansion of such a lesion is not conclusive for malignancy, and should not affect its biological behavior. Intraoperative frozen-section histology may prevent unnecessary resection of lung tissue. Extracapsular enucleation is the treatment of choice for sclerosing hemangiomas.
