A Becker's nevus typically appears as a single unilateral, well-demarcated, hyperpigmented patch over the upper trunk during adolescence. It uncommonly presents as multiple and bilateral patches and rarely involves a lower extremity. We describe the unusual case of a child with multiple, bilateral Becker's nevi of the trunk and lower extremities present since birth.
贝克尔痣通常在青春期时表现为上躯干出现单个单侧、边界清晰的色素沉着斑。它很少表现为多个双侧斑，且极少累及下肢。我们描述了一例罕见病例，一名儿童自出生起即有躯干和下肢多发双侧贝克尔痣。
