The tumors measured 1-15 cm in diameter (median 5 cm) and frequently were hemorrhagic and multinodular. There was a wide morphologic spectrum within and between cases, including areas similar to cavernous and capillary hemangioma, Dabska tumor, spindle cell and epithelioid hemangioendothelioma, various spindle cell sarcomas, or carcinoma.

Abstract The clinicopathologic, immunohistochemical, and ultrastructural features of soft tissue angiosarcomas are not well defined. Typically, epithelioid sarcoma starts as a small firm growth or lump that's painless. Liver Angiosarcoma may manifest as a single mass with satellite nodules or as a diffuse infiltrative mass throughout the liver tissue due to the atypical proliferation of endothelial cells in the hepatic sinusoids.
