A Case of Pulmonary Sclerosing Hemangioma with an Increased Size and Chest Discomfort on 10 Years' Follow-up

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 3.2×3.1 cm to 6.0×5.3 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.
