While cases of congenital port-wine stains (PWSs) are relatively common, cases of acquired PWSs are quite rare. Many of the reported cases of the acquired type have been reported to be related to previous trauma.
We encountered a case of acquired PWSs in a 3-year-old girl. Her parents noted that the lesions appeared in areas of antecedent trauma. This prompted us to review all reported cases of acquired PWSs and to assess the relationship to trauma. Among the 59 cases reported, there was a slight female predominance (female-male ratio, 35:24). Seventeen (29%) of the cases were related to trauma. One report evaluated the effectiveness of lasers in the treatment of acquired PWSs and found that 54% of patients treated with pulsed dye lasers had an excellent response or complete clearance.
Port-wine stains are not only congenital but can be acquired as well. Trauma can be one of the causes of acquired PWSs. To explain this phenomenon, various theories, including abnormal vascular repair and altered vascular innervation, have been proposed. Lasers are the treatment of choice in all cases of PWSs and may be more effective in those that are acquired.
先天性葡萄酒色斑（PWS）病例相对常见，而获得性PWS病例相当罕见。许多已报道的获得性病例据报道与既往创伤有关。
我们遇到一名3岁女孩患有获得性PWS。她的父母注意到病变出现在先前受过创伤的部位。这促使我们回顾所有已报道的获得性PWS病例，并评估其与创伤的关系。在报道的59例病例中，女性略占优势（男女比例为35:24）。其中17例（29%）与创伤有关。一份报告评估了激光治疗获得性PWS的有效性，发现54%接受脉冲染料激光治疗的患者有良好反应或完全清除。
葡萄酒色斑不仅可以是先天性的，也可以是获得性的。创伤可能是获得性PWS的原因之一。为了解释这一现象，已经提出了各种理论，包括异常血管修复和血管神经支配改变。激光是所有PWS病例的首选治疗方法，对获得性PWS可能更有效。
