Becker's nevus is a unilateral, hyperpigmented cutaneous hamartoma usually with hypertrichosis. It occurs predominantly in boys, becoming apparent during adolescence, although several cases of congenital Becker's nevus have been reported. Rarely it may be familial and as such is transmitted in an autosomal dominant pattern. We report a 16-month-old black boy with a hyperpigmented patch on his right shoulder and upper pectoral area that extended down his arm. The patient's father has a similar lesion with hair on his left shoulder which has been present since childhood. Histology of the child's lesion was consistent with Becker's nevus. We believe this to be the first reported case of a congenital Becker's nevus with a familial association.
贝克尔痣是一种单侧性、色素沉着性皮肤错构瘤，通常伴有多毛症。它主要发生于男孩，在青春期时变得明显，不过也有几例先天性贝克尔痣的报道。它很少有家族性，以常染色体显性模式遗传。我们报告一例16个月大的黑人男孩，其右肩部和上胸部有一色素沉着斑，并延伸至手臂。患儿的父亲在其左肩有一类似的伴有毛发的损害，自童年起就存在。患儿损害的组织学表现符合贝克尔痣。我们认为这是首例报道的有家族关联的先天性贝克尔痣。
