Sclerosing epitheloid angiosarcoma of bone and lung--intravascular sclerosing bronchioloalveolar tumor.

A 39-year-old woman was admitted to hospital with severe pain in the left shoulder due to an endothelial bone tumor. The tumor showed the same histologic signs as an intravascular sclerosing bronchioloalveolar tumor of the lung (IVBAT) which had been enucleated 2 years previously. This combination is uncommon. It is discussed whether the IVBAT is a malignant tumor with metastases or a benign tumor with coincidental tumors in other organs of the same endothelial vascular origin. We consider this to be an epitheloid angiosarcoma of the lung with, in our case, bone metastases; this is in agreement with some most recent reports on the disease.
