摘要

本文对4例靶样含铁血黄素沉积性血管瘤(THH)的临床和组织病理资料进行回顾性分析。典型损害：单个棕色或紫红色丘疹，直径为2~3 mm，周围见苍白窄带和瘀斑。组织病理示：管腔不规则扩张伴腔内乳头状突起和纤维蛋白性血栓形成，周围有弥漫红细胞漏出和炎细胞浸润。晚期间质内可见含铁血黄素沉积。4例患者均予手术切除治疗，均无复发。%We present four patients with targetoid hemosiderotic hemangioma (THH). The typical lesion was single brown or purple papule, about 2-3 mm diameter in size and surrounded by pale halo or petechiae. Histopathologic examination showed dilated vascular channels with the papilla and fibrin thrombus, surrounded by red blood cells and inflammatory cells.
