ReferencesBecker nevus，也称为贝克尔黑变病，是一种良性皮肤病。它可先天出现，也可在后天发展，表现为有毛或无毛的皮肤斑块。该病较少见，主要见于男性。随年龄增长，受累部位常逐渐变深，并可能长出多余毛发。某 29 岁跨性别患者就诊时，报告自 15 岁起皮肤出现小斑点，随后这些斑点逐渐扩大为斑块。体检发现其右侧胸部、肩部、背部及上臂呈毛发黑色斑块，边缘不规则。
Becker's nevus is also known as Becker melanosis. It is a benign lesion which can be presented as congenital or acquired with hairless or hypertrichotic lesions. It's a rare case which affects mainly male individuals. It is often pigmented and gets darker by time and excessive hair growth can be seen over it. A 29-year-old transgender patient presented with hyperpigmentation with the lesion which started at the age of 15 as a small hyperpigmented macule. The lesion increased gradually to form giant patches. On examination a right-side hyperpigmentation involving the anterior chest, shoulder, scapular region, upper arm with hypertrichosis and irregular margins.

Becker's nevus 是一种常见的皮肤病，其特征为单侧出现色素斑块，并伴有毛发生长增多。虽然有其他治疗选择，但激光是常用的治疗方式。已单独或联合使用不同类型的激光，波长范围为 504 至 10,600 nm，治疗次数为 1 至 12 次。结果差异较大，但不同波长激光的组合似乎更有效。副作用通常为轻度至中度发红。虽然激光通常安全，但对贝克尔痣的疗效仅为中等，效果并不理想。
Becker's nevus is a common pigmented dermatosis, usually featured by ipsilateral pigmented patch with hypertrichosis. Becker's nevus is often treated with various types of lasers although other regimens are available. A variety of lasers had been used alone or in combination to treat Becker's nevus. Laser wavelengths used for Becker's nevus ranged from 504 to 10,600 nm, while the number of treatment varied from 1 to 12 sessions. The clinical outcomes were mixed although combination of lasers with different wavelengths appeared to achieve a better efficacy. Adverse effects were usually mild to moderate erythema. While lasers are relatively safe, their efficacy for Becker's nevus is moderate.

○ 治疗
痣表面的毛发可通过激光去除，但由于痣本身复发率较高，激光去除往往难以根治。
