The third case of melanosis of the exocervix reported in the English literature is presented. Discovery was incidental at surgery for unrelated findings. The pathogenesis of melanosis is unknown, but the lesion apparently is innocuous. Biopsy should distinguish this entity from other pigmented lesions of the cervix, eg, malignant melanoma and blue nevus.
本文报告了英文文献中报道的第三例宫颈外黑色素沉着症病例。该病例是在因其他无关检查结果进行手术时偶然发现的。黑色素沉着症的发病机制尚不清楚，但该病变显然是无害的。活检应将此病变与宫颈其他色素沉着性病变，如恶性黑色素瘤和蓝痣相鉴别。
