Dermoscopy in the Diagnosis of Inflammatory and Infective Nail Disorders

The presentation focuses on the application of dermoscopy in diagnosing inflammatory and infective nail disorders, particularly nail psoriasis and onychomycosis. Dermoscopy can enhance the visualization of various nail abnormalities, such as pitting and splinter hemorrhages, allowing for better patient education through clear images. In cases of nail psoriasis, the identification of specific capillary patterns in the hyponychium is crucial for differentiation from other nail conditions. The presenter emphasizes the historical significance of dermatoscopic features in diagnosing onychomycosis, such as the identification of sharp margins and spikes at the proximal margin of the nail. Differentiating between onychomycosis and other nail disorders like leuconychia is also discussed, especially emphasizing the role of dermoscopy in recognizing dermatophytoma and making informed treatment decisions. The impact of nail polish on diagnostic clarity is highlighted, illustrating the necessity of thorough evaluations in patients presenting with nail changes. The speaker concludes by referencing a recently published book that consolidates this knowledge, advocating for the importance of dermoscopy in clinical practice.
