Dermoscopy allows early detection of melanoma also on acral volar skin. The majority of melanocytic nevi on palms and soles may show three major dermoscopic patterns: the parallel-furrow pattern, the lattice-like pattern, and the fibrillar pattern. Melanomas at these sites are characterized by the parallel ridge pattern. We present the case of a 59-year-old woman who had an oval papule of bluish color, measuring 0.6 x 0.9 cm, localized on her left sole, that had been present, unchanged, for more than 10 years. Dermoscopy showed a parallel ridge pattern. The histopathological examination revealed a combined blue nevus. We present this case to underline that on acral volar skin also intradermal nevi, such as combined blue nevi, may dermoscopically exhibit a parallel ridge pattern, simulating melanoma.
皮肤镜检查也能在手掌足底皮肤早期发现黑色素瘤。手掌和足底的大多数黑素细胞痣可能呈现三种主要的皮肤镜表现模式：平行沟模式、网格状模式和纤维状模式。这些部位的黑色素瘤以平行嵴模式为特征。我们报告一例59岁女性病例，其左脚底有一个椭圆形蓝色丘疹，大小为0.6×0.9厘米，已存在10多年且无变化。皮肤镜检查显示为平行嵴模式。组织病理学检查显示为混合性蓝痣。我们展示此病例以强调在手掌足底皮肤，诸如混合性蓝痣等皮内痣在皮肤镜检查时也可能呈现平行嵴模式，从而模拟黑色素瘤。
