    Abstract Introduction: Onychomycosis is a frequent complaint in dermatological practice and corresponds to the most common nail disease. The treatment of onychomycosis remains a challenge, as several factors end up compromising and making treatment difficult. Nail abrasion is considered a useful method in many cases. However, there is controversy about this approach, as there is an aerosol formation that could contaminate the environment and cause fungal changes or hypersensitivity reactions by the disseminated dust. We conducted a pilot study to investigate the fungal viability of nail particles from nails with onychomycosis after abrasion procedure.
    Methods: In this study, nail dust from the gloves and mask, used in the procedure, was collected from 9 patients with clinical and dermoscopic diagnoses of onychomycosis.
    Results: Hyaline septate hyphae were found in 12 materials (gloves and/or masks) from 7 patients. However, these hyphae were morphologically deformed or mutilated in all exams. In Mycosel® agar, there was no growth of any fungus.
    Discussion/conclusion: The absence of dermatophyte isolation in all fungal cultures may demonstrate that the deformed fungal structures shown are not viable and would not present risks of contamination after nail abrasion.
