Sclerosing hemangioma of the lung is uncommon benign neoplasm of uncertain histogenesis. Their radiologic appearance is relatively distinct and well defined. Recently we experienced 3 cases of sclerosing hemangioma of the lung in 54, 52, 51 years old women. The light microscopic findings are similar to the features reported by Liebow and Hubbell (1956).

Since sclerosing hemangioma of the lung was first described by Liebow and Hubbell in 1956, there have been several reports on cases occurring as a solitary nodule; however, sclerosing hemangiomas occurring as multiple nodules are extremely rare. The histogenesis of this tumor remains controversial and there are several hypotheses of the etiology. Three separate nodules were found in a 57-year-old housewife, one found in the right middle lobe, one in the apicoposterior segment of the left upper lobe, and one in the superior segment of the left lower lobe. The only symptom or sign presented was a dry cough. Apicoposterior segmentectomy of the left upper lobe and wedge resection of the superior segment of the left lower lobe were performed. The postoperative course was uneventful and the patient was discharged on the postoperative 15th day.

Sclerosing hemangiomas are rare benign neoplasms in pulmonary parenchyme, We analyzed CT findings of two cases of sclerosing hemangiomas of the lung in two adult females. Chest radiograph showed well-circumscuribed, round soft tissue mass with calcification in right lower lobe of one patient and without calcification and moderate or marked contrast enhancement was clearly demonstrated with CT scan. CT findings of contratst enhancement and contour of calcification allow differentiation of sclerosing hemangioma from other venign neoplasms or postinflammotory pseudotusrs of the lung.

This report describes a sclerosing hemangioma of the lung evaluated by MRI. The mass demonstrated hyperintense signal on T1 -weighted, proton density, and T2-weighted spin-echo images. Contrast-enhanced T1 -weighted images showed marked, homogeneous enhancement of the mass. The MR appearance is not specific for sclerosing hemangioma of the lung, as other benign tumors can appear similarly. However, the appearance of homogeneous enhancement within the mass on Gd-DTPA enhanced MR may suggest the diagnosis.

Pulmonary sclerosing hemangioma is a relatively rare neoplasm of the lung with polymorphic histologic features of 2 unifying cellular components including surface cuboidal cells and interstitial round cells. Pulmonary sclerosing hemangioma typically occurs in middle aged women with asymptomatic, peripheral, solitary, well-circumscribed lesions. Although it is pathologically benign, it reveals size growing and chest symptom. We here report a case of pulmonary sclerosing hemangioma in a 72-year-old woman. She presented chest discomfort. A chest radiography and a chest computed tomography scan showed growing size from 3.2x3.1 cm to 6.0x5.3 cm in left upper lung during 10 years' follow-up period. Surgical resection of lung revealed a distinct constellation of findings including 2 epithelial cell types, surface cells, and round cells, which form 4 architectural patterns, papillary, sclerotic, solid, and hemorrhagic. She was diagnosed as pulmonary sclerosing hemangioma and chest discomfort disappeared.

Sclerosing hemangioma is a rare, benign neoplasm of the lung, usually presented as a solitary pulmonary nodule in an otherwise asymptomatic middle-aged woman. Cytologically it shows papillary, sheet, and cyst-like arrangements representing three main histologic patterns of papillary, solid, and angiomatous ones, respectively. Herein, we report the fine needle aspiration cytology of 5 cases of sclerosing hemangioma of the lung. The most characteristic finding is cyst-like spaces intimately related to the papillary or solid cell nests. The tumor cells are relatively monotonous, round to oval, small to medium in size. They have small amount of eosinophilic cytoplasm. The nuclei are uniform, round and have small but conspicuous nucleoli. The tumor cells in one of the presenting cases are large with abundant cytoplasm and show moderate nuclear pleomorphism. The nuclear chromatin, however, is fine and even without exception, even in the case showing nuclear pleomorphism. Major differential diagnoses based on the cytologic findings are well-differentiated papillary adenocarcinoma, bronchioloalveolar carcinoma, and carcinoid tumor.
