阴茎雀斑样痣是指局部无症状的黄斑色素沉着过度，没有证据表明组织学异常。这种疾病的发病率尚不清楚，尽管据报道，10，000名17至25岁的男性中有14.2%患有色素痣。作者报告一例阴茎雀斑样痣，其组织学检查显示弥漫性黑素细胞增生伴局灶性色素沉着。一名25岁的白色男子提出了一个无症状的色素性病变的阴茎头的2年的时间。病变的大小一直在缓慢增加。该区域没有任何药物摄入、创伤或先前的皮疹史。在检查中，患者表现为黄斑色素沉着过度，棕褐色和黑色变化，轮廓不规则，有跳跃区域。
Penile lentigo refers to localized asymptomatic macular hyperpigmentation without evidence of histologic atypia. The incidence of this disease is not known although 14.2% of 10,000 males between the ages of 17 and 25 were reported to have pigmented nevi. Authors report a case of penile lentigo, the histologic examination of which showed diffuse melanocytic hyperplasia with focal atypia. A 25-year-old white man presented with an asymptomatic pigmented lesion on the glans penis of 2 years duration. The lesion had been slowly increasing in size. There was no history of any drug intake, trauma, or prior eruptions in that area. On examination, the patient showed macular hyperpigmentation of tan, brown, and black color variations irregular in outline with skip areas.
