A 7-year-old healthy girl presented with an 11-month history of an asymptomatic red, dome-shaped papule on her right medial elbow and 6-month history of linearly distributed, few millimeter, flesh-colored papules extending from and including the red papule. Histopathology demonstrated features of both a Spitz nevus and lichen striatus. The Spitz nevus was removed with a punch biopsy and the lichen striatus subsequently resolved. To our knowledge, co-localization of a Spitz nevus with lichen striatus has not been previously reported and highlights the potential association between the immunogenicity of Spitz nevi and the development of lichen striatus.
一位 7 岁健康女孩，右侧内肘出现一红色、半球形丘疹，无自觉症状，病史 11 个月；另有 6 个月病史的线性分布、数毫米、肤色丘疹，从红色丘疹开始延伸。组织病理学显示 Spitz 痣和线状苔藓的特征均存在。Spitz 痣通过打孔活检切除，线状苔藓随后消退。据我们所知，Spitz 痣与线状苔藓的共存以前没有报道过，这突显了 Spitz 痣的免疫原性与线状苔藓的发展之间的潜在关联。
