Becker nevus ，也稱為貝克爾黑變病，是一種良性皮膚病。它可以從出生時出現，也可以在以後發展，導致有或沒有毛髮的皮膚斑塊。這種情況並不常見，主要影響男性。隨著時間的推移，受影響的區域通常會變黑，並且那裡可能會長出多餘的毛髮。一名 29 歲的跨性別患者就診，皮膚上出現了 15 歲時開始出現的小斑點。隨著時間的推移，這些斑點變成了更大的斑塊。檢查發現，他們的右側胸部、肩膀、背部和上臂有毛髮黑斑，邊緣不規則。
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 是一種常見的皮膚病，其特徵是身體一側出現色素斑塊並伴隨額外的毛髮生長。儘管有其他選擇，但通常使用雷射進行治療。單獨或一起使用了不同類型的雷射器，波長範圍為 504 至 10,600 nm，療程範圍為 1 至 12。結果各不相同，但組合不同波長的雷射似乎效果更好。副作用通常是輕度至中度發紅。雖然雷射通常是安全的，但它們對貝克爾痣的效果中等（不是很好）。
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.

○ 治療
覆蓋在痣上的毛髮可以用雷射去除。但由於痣的復發率很高，要用雷射去除痣幾乎是不可能的。
