Erythema nodosum following COVID‐19 vaccination: A case report and literature review

Abstract

Abstract There have been a few reported cases of erythema nodosum (EN) after coronavirus disease 2019 (COVID‐19) vaccination. A 48‐year‐old healthy woman was referred to our department with multiple erythematous nodules of varying sizes on her extremities 10 days after receiving the third COVID‐19 vaccine dose. The clinical and pathological findings of the patients were consistent with EN. We reviewed 18 EN cases post‐COVID‐19 vaccination. Considering the low number of reported EN cases, a causal link between EN and COVID‐19 vaccination is still under debate.
