To the editor: 34 Longitudinal melanonychia (LM) is the presenting sign of nail unit melanoma (NUM) in 2/3 35 of cases and is therefore among the most important conditions managed by dermatologists. In 36 normal times, referral for LM would prompt an expedited appointment for clinical 37 examination and dermoscopy.1 However, due to SARS-CoV-2, dermatologists have been 38 asked to reconsider “urgent/emergency” conditions. The COVID-19 pandemic has propelled 39 physicians to unexpectedly adopt telemedicine without adequate guidance for managing LM 40 patients.
