With the expansion of the COVID-19 vaccination drive, an increasing number of adverse effects are surfacing. A 74-year-old woman presented with multiple erythematous and itchy patches on several sites. She had no relevant medical history, apart from the first AZD1222 vaccination 1 month previously. Microscopically, epidermal changes, including mild spongiosis and parakeratosis, were observed. Tight perivascular lymphocytic infiltration (coat-sleeve pattern) was also observed in the dermis. The final diagnosis was erythema annulare centrifugum (EAC) induced by SARS-CoV-2 vaccination. Based on this report, dermatologists should be aware of the possibility of EAC from the AZD1222 vaccination. © 2021 British Association of Dermatologists.
