Scaling skin disorders have similar features. Careful inspection to determine the characteristics of the primary lesion, along with distribution patterns and performance of routine diagnostic tests, usually lead to a correct diagnosis. Potassium hydroxide examination should be performed on most scaling skin disorders. If a microscope is not readily available, skin scrapings should be sent to a microbiology laboratory, or a microscope should be purchased and training obtained. A binocular microscope is preferable to view fungal hyphae. KOH examination requires supervised experience to become proficient.
鳞屑性皮肤病有相似的特征。仔细检查以确定原发性皮损的特征，连同分布模式以及进行常规诊断测试，通常会得出正确的诊断。大多数鳞屑性皮肤病都应进行氢氧化钾检查。如果没有现成的显微镜，皮肤刮屑应送往微生物实验室，或者应购买显微镜并接受培训。双目显微镜更适合观察真菌菌丝。氢氧化钾检查需要有监督的经验才能熟练掌握。
