Rapidly progressive invasive sclerosing hemangioma ; a case report

Abstract

A 48-year old woman was admitted to our hospital with the complaint of bloody sputum. Her chest X-ray taken two months befor admission showed only a faint small shadow in the right upper lung field, but two months after admission, her chest X-ray film showed a large dense shadow, approximately 3 × 4 cm in diameter. Right upper lobectomy was performed. Histological examination revealed so-called sclerosing hemangioma with bronchial and vascular invasion. We concluded that sclerosing hemangioma can become malignant.
