Pityriasis rosea-like eruption after Pfizer-BioNTech COVID-19 vaccination.

A 35‐year‐old male presented with an extremely itchy exanthem after Pfizer–BioNTech COVID‐19 vaccination. A single oval erythematous lesion appeared on the thigh after the first dose (a) and progressed insidiously to a papulosquamous rash on the trunk and proximal extremities (b). After the second dose, it notably flared up (c). Serological evaluation for human herpesvirus reactivation was negative. Pityriasis rosea‐like eruption was diagnosed. Antihistamines and topical betamethasone were initiated, with clinical improvement after 2 weeks. Considering that immunization programmes are being conducted worldwide, it is important to increase awareness within the medical community, so that appropriate management be provided.
