title: Sclerosing hemangioma of the lung: radiographic and pathological study.
abstract: The clinical, radiographic, and pathological features of 10 patients with sclerosing hemangioma of the lung seen between 1974 and 1990 were reviewed. The incidence of sclerosing hemangioma was 22.2% of benign tumors surgically resected during that time. There were 2 male and 8 female patients aged 15 to 77 years at operation, and 9 patients were asymptomatic. All 10 patients had a solitary tumor with a well-defined homogeneous round or oval shadow on chest roentgenograms. Chest computed tomography revealed a homogeneous soft-density mass in 4 patients and a low-density portion within the tumor because of a cystic change in 1 patient. Microscopically, 5 patients had a preponderantly solid pattern, 3 had a preponderantly papillary pattern, and 1 patient had a preponderantly sclerotic pattern. One patient had an equal mixture of solid and papillary patterns. Nine of the 10 tumors consisted of a mixture of at least three of the four major patterns. Regarding treatment, thoracotomy is indicated for a definite diagnosis. If a benign tumor is suspected at operation, an intraoperative frozen section is recommended. Once the diagnosis has been established as sclerosing hemangioma, a limited resection is indicated.
