Alopecia Areata pós-Covid-19: relação causal ou casual?

Abstract

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.

Reply to early-onset effluvium secondary to COVID-19 and body hair effluvium

“…To add to the list of differential diagnoses, for cases with later onset and a longer duration, clinically manifesting as alopecia (without expected regrowth of the hair shafts), alopecia areata has been reported after COVID-19 infection as a straightforward diagnosis of patchy areas of alopecia. 2,3 However, diffuse alopecia areata can be difficult to diagnose clinically and can be initially misdiagnosed as chronic telogen effluvium.…”
