Abstract：
Becker\'s nevus (BN) is a kind of epidermal cutaneous hamartoma. A noticeable hyperpigmented patch with a big, unilateral, hyperpigmented macule and irregularly shaped borders is the manner in which BN often presents. In this case, a 16-year-old boy has asymptomatic dark brown colored follicular macule on the left side of the cheek shortly after birth. The lesions were initially inconspicuous but gradually became darker as time passed. The macules on some of them grew hair. This case of BN with apparent hypertrichosis on one side of the cheek, which made it challenging to make a differential diagnosis with whiskers. The primary point of differentiation is that the lesions of BN only appear unilaterally. On the other hand, the face has whiskers on both sides. Additionally, BN will show hyperpigmentation whereas whiskers do not. In conclusion, for its unusual clinical presentation, we believe that reporting this case may help dermatologists avoid misdiagnosing similar cases.
摘要：
贝克尔痣（BN）是一种表皮皮肤错构瘤。明显的色素沉着斑，有一个大的，单边,色素性斑疹和不规则形状的边界是BN经常出现的方式。在这种情况下,一名16岁男孩出生后不久，脸颊左侧无症状的深棕色滤泡性黄斑。病变最初不显眼，但随着时间的流逝逐渐变暗。其中一些斑疹长出了头发。此例BN在脸颊一侧有明显的多毛症，这使得用胡须进行鉴别诊断具有挑战性。分化的主要点是BN的病变仅单侧出现。另一方面,脸两边都有胡须。此外,BN将显示色素沉着过度，而晶须则没有。总之,因为它不寻常的临床表现，我们认为，报告该病例可能有助于皮肤科医生避免误诊类似病例。
