Acute Generalized Exanthematous Pustulosis After the First Dose of Favipiravir in a Patient with COVID-19 Pneumonia: A Case Report and Literature Review
Keywords:
acute generalized exanthematous pustulosis, AGEP, COVID-19Abstract
A 47-year-old man was referred to a hospital for treatment of coronavirus disease 2019 (COVID-19) pneumonia and developed progressive generalized pustular skin lesions over entire trunk, back and both upper extremities after the first dose of oral favipiravir for the treatment of his condition. No infectious causes of pustular lesions were identified upon investigations, and the diagnosis of acute generalized exanthematous pustulosis (AGEP) was made. With the prompt withdrawal of favipiravir, along with the initiation of systemic and topical corticosteroid treatment, his skin lesions resolved with desquamation and erythema within 3 days. Dermatologic adverse reactions from favipiravir, the novel antiviral agent for the treatment of SARS-COV2 infection, are uncommon. The association of favipiravir and acute generalized exanthematous pustulosis (AGEP), a severe form of skin reaction, remains unclear. We reported a case of patient who developed AGEP with the oral favipiravir as the causative agent.
