Transverse Leukonychia and Beau Lines Following COVID-19 Vaccination
Nail abnormalities associated with SARS-CoV-2 infection that have been reported in the medical literature include nail psoriasis,1 Beau lines,2 onychomadesis,3 heterogeneous red-white discoloration of the nail bed,4 transverse orange nail lesions,3 and the red half‐moon nail sign.3,5 It has been hypothesized that these nail findings may be an indication of microvascular injury to the distal subungual arcade of the digit or may be indicative of a procoagulant state.5,6 Currently, there is limited knowledge of the effect of COVID-19 vaccines on nail changes. We report a patient who presented with transverse leukonychia (Mees lines) and Beau lines shortly after each dose of the Pfizer-BioNTech COVID-19 messenger RNA vaccine was administered (with a total of 2 doses administered on presentation).
A 64-year-old woman with a history of rheumatoid arthritis presented with peeling of the fingernails and proximal white discoloration of several fingernails of 2 months’ duration.
