Dear Editor, Coronavirus disease (COVID-19) has spread across the globe from December 2019 determining the current pandemic. It is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), an RNA virus of the betacoronavirus family. Besides COVID-19 respiratory symptoms, skin manifestations have been largely reported, such as chilblain-like lesions, urticaria, maculopapular lesions, and also hair loss. 1 We report a case of alopecia areata(AA) which occurred after SARS-CoV-2 infection. In October 2020, a female patient aged 29 was admitted to our post-COVID Dermatology Office, complaining progressive hair loss starting 6 months before our observation. The patient had been diagnosed with SARS-CoV-2 infection in March 2020, following positive naso-oropharyngeal swab test. Reported symptoms were fever and dry cough, treated with paracetamol and azithromycin and requiring no hospitalization. The patient recalled that hair loss started 1 month after the onset of COVID-19, firstly on vertex and parietal regions, with patchy distribution, then involving the total scalp surface. A trichological evaluation showed a generalized hair loss of the scalp, with regrowing hairs of different lengths ( Figure 1A SARS-CoV-2-induced telogen effluvium: a multicentric study COVID-19: association with rapidly progressive forms of alopecia areata Alopecia areata in a patient with SARS-Cov-2 infection Evaluation of the relationship between alopecia areata and viral antigen exposure Serum concentrations of IL-2, IL-6, IL-12 and TNF-α in patients with alopecia areata Stress-induced premature senescence of dermal papilla cells compromises hair follicle epithelialmesenchymal interaction
