Vulvar melanocytic nevus: case report

ABSTRACT Pigmented vulvar lesions are uncommon; they occur in about 10%-12% of women and include benign and malignant processes, as well as post-inflammatory changes and hyperchromatic lesions due to melanin increase. Among the benign processes, there are vulvar nevi, present in 2% of adult women. There is a small subgroup classified as atypical melanocytic nevi that account for 5% of vulvar nevi and is associated with younger women. Despite the importance of early diagnosis, the clinical history and time of evolution of the lesion are not well explored, as patients rarely examine the region, as do dermatologists. We report a case of an melanocytic nevus in the small lip in a 43-year-old woman.

摘要：色素性外阴病变并不少见，约见于10%~12%的女性群体，涵盖良性与恶性病变，同时包括炎症后改变及因黑色素增多引发的色素沉着性病变。在良性病变范畴内，外阴痣（vulvar nevi）在成年女性中的发生率约为2%。其中有一小类被归类为不典型黑素细胞痣（atypical melanocytic nevi），约占外阴痣的5%，多见于年轻女性。尽管早期诊断意义重大，但由于患者与皮肤科医生均极少对该区域进行检查，病变的临床病史及演化时长尚未得到充分研究。本文报告1例发生于43岁女性小阴唇的黑素细胞痣病例。
