In a 29-year-old woman suffering from hereditary palmoplantar keratoderma of the Unna Thost variety, psoriasis appeared at an age of 28 years. The keratoderma on the soles was complicated with a dermatophyte infection, which made the differential diagnosis towards psoriasis difficult. Histopathologic examination of punch biopsy from the soles showed no conclusive signs of psoriasis. An increased thickness of the horny layer, which in PAS staining showed fungus hyphae, was found.
一名29岁患有尤纳 - 托斯特型遗传性掌跖角化病的女性，在28岁时出现了银屑病。足底的角化病合并皮肤癣菌感染，这使得与银屑病的鉴别诊断变得困难。对足底进行钻孔活检的组织病理学检查未发现银屑病的确切迹象。发现角质层增厚，在PAS染色中可见真菌菌丝。
