New-Onset Henoch–Schonlein Purpura after COVID-19 Infection: A Case Report and Review of the Literature

Extrapulmonary manifestations of COVID-19 infection include a wide spectrum of cutaneous, endocrine, and cardiovascular complications. We report three cases of new-onset Henoch–Schonlein purpura (HSP) in COVID-19 infected children that were diagnosed and treated in Abha Maternity and Children Hospital, Saudi Arabia, between 28(th) July 2020 and 10(th) August 2020. All three cases were males younger than 5 years of age that presented with Henoch–Schonlein purpura characteristic rash and arthralgia without a recent history of any infection, especially respiratory infections. They all tested positive for COVID-19. At the time of the admission, pediatric COVID-19 cases were managed conservatively and we ruled out any other diagnosis before establishing the diagnosis of Henoch–Schonlein purpura according to the clinical picture. The three boys responded significantly to prednisolone and achieved a rapid recovery. We present the clinical scenario and laboratory tests of these children along with pictures of the lesions detected in each case.
