Morbilliform Eruption Post PfizerBioNTech COVID-19 Vaccination: A Case Report and Future Recommendations - Abstract
A man in his 80’s presented with a 1-month history of pruritic morbilliform rash over his upper and lower extermities, sparing the trunk and face. It started after 3 days of receiving the 1st dose of Pfizer-BioNTech COVID-19 vaccine and worsened few hours after receiving the 2nd dose of the vaccine. He did not improve on high potent topical corticosteroid, nor by combining 2 types of antihistamines. Despite there was a noticeable improvement of his symptoms after receiving a short course of oral corticosteroid, the same morbilliform rash ascended from the distal parts of his extremities to involve the proximal parts, and then gradually improved after 3 weeks. Histopathology reported signs of dermatitis, no features of vasculitis were noted and DIF was negative. We believe that the ascending of the rash is a unique finding in our case, moreover, our patient had a relatively longer time to reach full recovery from this adverse event.
