Abstract
A 69-year-old female was found to have a round lesion in the right lung in 1981. It was diagnosed a benign tumor of the lung by the radiologic examination. In 1996, The tumor increased in size slightly during a 15-year follow-up period. Under general anesthesia, three trocars were inserted through the right intercostal space for operation. Thoracoscopic enucleation of sclerosing hemangioma of the lung was successfully performed. Immunostaining of the tumor revealed positive expression of alpha-smooth muscle actin, cytokeratin, CD68 and vimentine. C-myc, p53, CD34, estrogen receptor and progesterone reseptor were negative. Thoracoscopic enucleation is considered to be indicated for sclerosing hemangioma of the lung during a long term follow-up.
