Blue nevus, a pigmented skin lesion, affects the dermal melanocytes that are rich in melanin. Its occurrence on skin has been well described in literature. Less commonly, involvement of mucosal surfaces especially genitourinary tract has also been noticed. Here we present a rare case of a blue nevus involving the rectum. So far there has been only one prior description of the blue nevus involving the gastrointestinal mucosa. Differentiation of this lesion from melanoma is the key. Simple excision of the blue nevus with a biopsy forceps during the colonoscopy is an effective management.
蓝痣是一种色素沉着性皮肤病变，影响富含黑色素的真皮黑素细胞。其在皮肤上的发生在文献中已有充分描述。较少见的是，黏膜表面尤其是泌尿生殖道受累也已被注意到。在此，我们报告一例罕见的累及直肠的蓝痣病例。到目前为止，仅有一篇关于累及胃肠道黏膜的蓝痣的先前描述。将此病变与黑色素瘤鉴别是关键。在结肠镜检查期间用活检钳简单切除蓝痣是一种有效的处理方法。
