This study aimed to describe 2 cases of vulvar psoriasis and vitiligo resulting in a striking clinical appearance.
Case 1 was of a 41-year-old woman concerned about a dark pigmentation around the introitus. Case 2 was of an 80-year-old woman with vulvar itch and red, white, and brown areas.
The vulva in each case showed a tricolored appearance of well-demarcated red, white, and brown colors. Biopsies showed psoriasis superimposed on vitiligo in the red, vitiligo in the white, and normal skin in the brown areas.
When psoriasis and vitiligo are colocalized, the redness of the psoriasis may mask the vitiligo resulting in a striking red, white, and brown tricolored appearance.
本研究旨在描述 2 例外阴银屑病和白癜风导致显著临床表现的病例。
病例 1 为 41 岁女性，因阴道口周围出现暗色素沉着而就诊。病例 2 为 80 岁女性，外阴瘙痒，呈红色、白色和棕色区域。
每个病例的外阴均呈现出界限分明的红色、白色和棕色三色外观。活检显示红色区域为银屑病合并白癜风，白色区域为白癜风，棕色区域为正常皮肤。
当银屑病和白癜风同时存在时，银屑病的红色可能会掩盖白癜风，导致显著的红、白、棕色三色外观。
