“…Although most cases of EAC are idiopathic, it has been suggested that the condition is a hypersensitivity reaction to antigens, and it has been linked to cutaneous or systemic infections, malignancy, drugs and pregnancy. Recently, there was a case of EAC suspected to be triggered by SARS‐CoV‐2 infection, which suggests that proinflammatory cytokines released during SARS‐CoV‐2 infection could cause the EAC 4 . We believe this case to be the result of a delayed‐type hypersensitivity or T‐cell–mediated immune reaction to the vaccine.…”

Similar to a previous study showing a high incidence of reactions to the first vaccine dose, but not to the same vaccine after the second dose, 5 our case showed occurrence of EAC only after the first injection of the AZD1222 vaccine.…”

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.
