Abstract Background, dermoscopy is a non-invasive diagnostic technique that allows the observation of morphological features that are not visible to the naked eye. Dermoscopy is helpful for the diagnosis of many nail diseases as it allows evaluation of parts of nail apparatus including the nail plate surface, the nail matrix, the nail bed, the periungual folds and the hyponychium. Onychomycosis is very common nail disease, it accounts for up to 50% of nail diseases and 30% of all superficial fungal infection. Onychomycosis is essentially diagnosed by fungal culture but it needs experienced microbiologist and also expensive technique so many dermatologists tend to make a presumptive diagnosis of onychomycosis and prescribe the treatment without mycological confirmation. Objectives, this work aimed to evaluate demoscopy as alternative low cost tool for diagnosis of onychomycosis instead of high cost fungal culture. Patients and methods, this study was carried out on 44 patients with a clinically suspected onychomycosis. For each patient, digital dermoscopic imaging of nail was done. Also, nail scraping from all cases were collected and cultured on sabouraud’s dextrose agar medium and dermatophyte test agar medium. Clinical results: In our study, the age of our patients ranged between 11-68 years with a mean age of 37 years. As regard gender of the studied cases, there were 4 males (9.1%) and 40 females (90.9%). |
