Abstract：
The follicular variant of Becker\'s nevus is an under-reported entity. We present the rare occurrence of follicular Becker\'s nevus in 7 patients, confirmed through dermoscopy and histopathological examination. Dermoscopy shows perifollicular hypopigmentation surrounded by a well-defined net-like pigmentation corresponding clinically to the presence of folliculocentric macules. Histology shows prominent basal and suprabasal melanization surrounding the follicle, corresponding to well-defined net-like pigmentation seen on dermoscopy. However, the melanization does not extend along the entire length of the follicular epithelium leading to perifollicular hypopigmentation on dermoscopy. Though biopsy is confirmatory, it is not usually necessary.
摘要：
贝克尔痣的卵泡变异体是一个报道不足的实体。我们介绍了7例患者中罕见的滤泡Becker痣的发生，通过皮肤镜检查和组织病理学检查证实。皮肤镜检查显示卵泡周围色素沉着不足，周围有明确定义的网状色素沉着，临床上与卵泡中心性黄斑的存在相对应。组织学显示毛囊周围突出的基底和基底上黑化，对应于在皮肤镜上看到的明确定义的网状色素沉着。然而,黑化不会沿着卵泡上皮的整个长度延伸，从而在皮肤镜检查中导致卵泡周围色素沉着不足。虽然活检是确证的，通常没有必要。
