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.
一名36岁女性因单发肝脏肿瘤就诊。大体检查显示，肿瘤最大直径为9厘米，包膜完整；呈红色，有多处出血灶。显微镜检查发现两种不同的形态：中央为海绵状血管瘤，周围是外周血管肉瘤。据我们所知，目前尚未有此类病例的报道。本文对发生于海绵状血管瘤内的肝脏血管肉瘤的可能发病机制、影像学及病理学表现进行了讨论。
