Perinevoid alopecia has been described as an associated alopecia surrounding a pigmented nevus due to an inflammatory response against nevus structures. It is described as a part of other nevocentric phenomena in which a cellular inflammatory response against nevus antigens develops. A 35-year-old male presented with a unique area of non-scarring alopecia surrounding an asymptomatic, pigmented nevus with a 1-month evolution. Trichoscopic and histologic findings were compatible with alopecia areata (AA). One month after excision, hair regrowth was reported by the patient. We concluded that perinevoid alopecia is an extremely rare clinical presentation of AA associated with a central, pigmented nevus where a cellular inflammatory response is triggered against hair follicles, nevoid cells, and melanocytic structures.
阴部样秃发被描述为由于针对痣结构的炎症反应而围绕色素痣的一种相关秃发。它被描述为其他以痣为中心的现象的一部分，其中会发生针对痣抗原的细胞炎症反应。一名35岁男性出现一个独特的非瘢痕性秃发区域，该区域围绕着一个无症状的色素痣，病程1个月。皮肤镜和组织学检查结果与斑秃（AA）相符。切除术后1个月，患者报告毛发再生。我们得出结论，阴部样秃发是AA的一种极其罕见的临床表现，与中央色素痣相关，在此情况下会触发针对毛囊、痣细胞和黑素细胞结构的细胞炎症反应。
