Molnupiravir-associated nail and hair fluorescence on Wood's lamp examination.

In a patient who had been treated with molnupiravir, nail and hair fluorescence were observed under Wood’s lamp examination. The fluorescence persisted even after 90 days following the last dose of molnupiravir. To the best of our knowledge, this is the first case reporting molnupiravir-associated nail and hair fluorescence.
