Portwine stain - 焰色痣
焰色痣 (Portwine stain)可以用激光治疗，但价格昂贵且耗时。

Flash-lamp pulsed dye laser (FPDL) 目前被广泛认为是可用于治疗表面血管问题的最精确的激光。在这项研究中，我们收集了十年来使用染料激光治疗各种血管疾病患者的经验数据 (telangiectasia, rhinophyma, port-wine stains, cherry and spider angiomas, and vascular tumors such as cherry angiomas, infantile hemangiomas, port wine stains, rhinophyma, spider angiomas, and telangiectasia) 。
The Flash‐lamp pulsed dye laser (FPDL) is nowadays considered the most precise laser currently on the market for treating superficial vascular lesions. In this study, we gathered data from 10 years of experience regarding dye laser treatment of patients presenting vascular malformations such as telangiectasia, rhinophyma, port‐wine stain, cherry and spider angioma and vascular tumours: cherry angioma, infantile haemangioma, port wine stain, rhinophyma, spider angioma, telangiectasia

Port-wine stain (PWS) 也称为 nevus flammeus 。它是婴儿皮肤上由异常血管引起的粉红色或红色斑块。它在出生时就存在并终生存在，通常出现在脸上。重要的是要将其与单纯痣或鲑鱼斑区分开来，后者会随着时间的推移而褪色。
Nevus flammeus or port-wine stain (PWS) is a non-neoplastic congenital dermal capillary hamartomatous malformation presenting as a pink or red patch on a newborn's skin. It is a congenital skin condition that can affect any part of the body and persists throughout life. The nevus flammeus is a well-defined, often unilateral, bilateral, or centrally positioned pink to red patch that appears on the face at birth and is made up of distorted capillary-like vessels. It needs to be differentiated from a nevus simplex/salmon patch, which is usually seen along the midline and disappears over time. An acquired port-wine stain, clinically and histopathologically indistinguishable from congenital capillary malformation, has been reported to develop in adolescents or adults, usually following trauma.

治疗 PWS 对于减少其对心理健康的影响以及减少结节和组织肿大非常重要。尽早开始治疗可能会带来更好的结果。 Pulsed dye laser (PDL) 被广泛认为是所有类型 PWS 的最佳选择，无论其大小、位置或颜色。
Treatment of PWB is indicated to minimize psychosocial impact and diminish nodularity, and potentially tissue hypertrophy. Better outcomes may be attained if treatments are started at an earlier age. In the United States, pulsed dye laser (PDL) is the gold standard for all PWB regardless of the lesion size, location, or color. When performed by experienced physicians, laser treatment can be performed safely on patients of all ages. The choice of using general anesthesia in young patients is a complex decision which must be considered on a case by case basis.

焰色痣 (portwine stain) 最常出现在面部，但也可能出现在身体的任何部位，特别是颈部、上半身、手臂和腿部。早期污渍通常呈扁平状且呈粉红色。随着孩子的成熟，颜色可能会加深为深红色或紫色。成年后，病变可能会增厚或形成小肿块。
○ 治疗
血管激光有一定效果，但需要昂贵的激光设备和数年的长期治疗。由于病变随着年龄的增长而变厚，激光治疗的效果可能会降低，这可能是一个问题。粉红色病变通常比红色病变更难治疗，因为它们血管化较深。
