| pubmed-article:3039630 | pubmed:abstractText | Two very different uncommon pulmonary tumors continue to bear the misleading names originally given them. The intravascular bronchioloalveolar tumor (IVBAT) is not an epithelial tumor, but is an incurable multifocal primary pulmonary angiosarcoma with a variable and often indolent clinical course. Conversely the sclerosing hemangioma of the lung is not a vascular tumor, but is a solitary benign epithelial tumor of uncertain histogenesis with a complex architecture. | lld:pubmed |
