Several presentations of onychomycosis: distolateral subungual (DLSOM), superficial white, proximal subungual, endonyx, and total dystrophic (TDOM). Although the diagnosis relies on mycological results, there are three specific dermoscopic findings for onychomycosis: a jagged edge of the onycholytic area, with spikes directed to the proximal fold, white\u2010yellow longitudinal striae in the onycholytic nail plate, and colored parallel bands.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aims<\/jats:title><jats:p>The objective of this diagnostic cross\u2010sectional study was to evaluate the diagnostic accuracy of dermoscopy as a low\u2010cost tool compared with fungal culture in patients with onychomycosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients\/Methods<\/jats:title><jats:p>This study was carried out on 40 patients with a clinical diagnosis of onychomycosis collected from dermatology outpatient clinic of Alzahraa University Hospital after approval from the research ethics committee of Al\u2010Azhar University. For each patient, dermoscopic imaging of nail was done. And nail scrapings, culture on sabouraud's dextrose agar medium, and dermatophyte test agar medium.
