Although many cells between vacuoles and collapsed capillaries/sinuses appear epithelioid with oval vesicular nuclei, single nucleoli and plump cytoplasm, I do not see enough atypia to worry about malignant neoplasm. The lobular architecture, the anatomic location (underneath tongue mucosa) and numerous associated blood vessels are consistent with that of a lobular capillary hemangioma (or pyogenic granuloma), but the epithelioid appearance of constituent cells would suggest epithelioid hemangioendothelioma.

纤维分隔小叶状，小叶中2种细胞，一种圆形或卵圆形，核圆形，空淡，核仁明显，一种胞浆透亮，核印戒状，包绕前者，形成小巢状。可见丰富的血管、裂隙、色素（含铁血黄色？黑色素？其他？）、散在红细胞。考虑
1、血管源性肿瘤：上皮样血管瘤？上皮样血管内皮瘤？血管肉瘤？
2、血管母细胞瘤？
3、幼年型色素痣？不知舌头能发生吗？
4、恶黑？年龄太小。
5、纤维组织细胞瘤？硬化性血管瘤？
6、颗粒细胞瘤？舌头容易发生，但此例不像。
呵呵，范老师提供的，一定难度大，我先猜猜吧。大家继续，谢谢！
