title: [A case of liver angiosarcoma arising in a pre-existing cavernous hemangioma].
abstract: A 36-year-old woman presented with a solitary hepatic tumor. Macroscopically, the tumor measured 9 cm in greatest diameter, and was well encapsulated; it was reddish, and showed multiple foci of hemorrhage. Microscopic examination revealed two different patterns: a peripheral angiosarcoma surrounding a centrally located cavernous haemangioma. To our knowledge, such an entity has not been reported up to now. Possible pathomechanisms, radiological and pathological findings of this angiosarcoma of liver arising within a cavernous haemangioma are commented.
