Mucinous nevus is an uncommon entity classified as either a cutaneous mucinosis or a connective tissue nevus. The condition presents as grouped papules and coalescent plaques growing in a unilateral or zosteriform manner. The key histopathological feature is a band-like deposition of mucin in the superficial dermis. A 34-year-old male presented with grouped gray-brown papules and confluent plaques exhibiting a zosteriform distribution on the right side of the lower back. The lesions had commenced in childhood. Histological examination revealed mucin deposition in the papillary dermis. Thus, we diagnosed a mucinous nevus. To date, only a few reports of such nevi have been reported in the literature. Therefore we report a rare case of mucinous nevus.
黏液性痣是一种罕见的疾病，归类为皮肤黏液沉着病或结缔组织痣。该病表现为成群的丘疹和融合性斑块，呈单侧或带状分布生长。关键的组织病理学特征是在真皮浅层有带状黏液沉积。一名34岁男性患者，下背部右侧出现成群的灰棕色丘疹和融合性斑块，呈带状分布。这些病变始于童年。组织学检查显示乳头真皮中有黏液沉积。因此，我们诊断为黏液性痣。迄今为止，文献中仅报道了少数此类痣的病例。因此，我们报告一例罕见的黏液性痣病例。
