Abstract
COVID-19, a disease that causes flu-like syndrome and acute respiratory failure, has been shown to cause damage to several other organs and systems. Several dermatological manifestations have been regular. We report a case of Alopecia Areata possibly triggered by COVID-19 in a patient who, despite his negative SARS-COV 2 RT- PCR, presented IgM reactor, in addition to classic symptoms related to the disease.We believe that a COVID-19 can trigger the autoimmune immune response with the consequent production of interferons that led to Alopecia areata.
