Onychomycosis is a fungal nail infection caused primarily by dermatophytes. Several other nail disorders, including psoriasis, can simulate onychomycosis. Accurate diagnosis is therefore vital for the ongoing treatment and management of onychomycosis and to avoid misdiagnosis and treatment delay, which can be both lengthy and costly. Often, a combination of histologic and laboratory techniques is used to obtain an accurate diagnosis. The potential diagnostic challenges associated with the differential diagnosis of onychomycosis caused by dermatophytes and the most common techniques used to confirm the diagnosis are discussed.
甲真菌病是一种由真菌引起的指甲感染，主要由皮肤癣菌引起。其他几种指甲疾病，如银屑病，可以模拟甲真菌病。因此，准确的诊断对于甲真菌病的持续治疗和管理至关重要，以避免误诊和治疗延误，这可能既漫长又昂贵。通常，结合组织学和实验室技术来获得准确的诊断。讨论了与由皮肤癣菌引起的甲真菌病的鉴别诊断相关的潜在诊断挑战，以及用于确认诊断的最常见技术。
