Nail Discoloration during the COVID-19 Pandemic.

A 45-year-old woman presented to the outpatient dermatology clinic during the COVID-19 pandemic with a painless green discoloration of several fingernails present for 1 week (Figure 1). The patient had no significant past medical history and was not taking any medication. No other findings were noted. There was no history of nail trauma or past fungal infection of the nail. The patient admitted that she had frequent hand washing, given the current pandemic, and never used protective gloves in everyday activities.
