Sclerosing hemangioma of the lung: a clinicopathologic study.

The clinical and pathological features of 11 cases with sclerosing hemangiomas of the lung seen between 1982, and 1992 were reviewed. There were 1 male and 10 female patients aged 15 to 74 years (mean age, 53 years) at operation. Among the 11, 4 were asymptomatic, with the tumor discovered only on routine chest roentgenograms. All 11 patients had a solitary tumor showing as a well-defined homogeneous round or oval shadow on chest x-rays. Microscopically, 8 of the 11 tumors consisted of a mixture of the four major patterns: hemorrhagic, sclerotic, papillary and solid. Five patients received enucleation; four, wedge resection; one, segmentectomy and one, lobectomy. Since this tumor is usually clinically benign and surgically curative, thoracotomy and complete removal of the tumor by limited resection is recommended.
