Hemangiomas of the head and neck are considered to be benign tumors of infancy that are characterized by a rapid growth phase with endothelial cell proliferation, followed by gradual involution. Central hemangiomas are a rare occurrence and even rarer are the hybrid tumors of central hemangiomas with odontogenic tumors such as ameloblastomas. This paper reports a case of one such hybrid tumor in a middle aged adult clinical presenting as a mandibular swelling with indistinct mixed radiographic presentation and histopathologically comprising of intimately associated hemangiomatous vascular channels and typical ameloblastic areas. To the authors' knowledge this is the sixth case of such a hemangiomatous ameloblastoma which has been reported till date.
头颈部血管瘤被认为是婴儿期的良性肿瘤，其特征是内皮细胞增殖的快速生长阶段，随后逐渐消退。中央血管瘤很少见，而中央血管瘤与牙源性肿瘤（如成釉细胞瘤）的混合肿瘤更为罕见。本文报告了一例中年成年人的此类混合肿瘤病例，临床表现为下颌肿胀，影像学表现模糊且混合存在，组织病理学检查显示由紧密相连的血管瘤性血管通道和典型的成釉细胞区域组成。据作者所知，这是迄今为止报道的第六例此类血管瘤性成釉细胞瘤病例。
