Henoch-Schoenlein Purpura Following Severe Acute Respiratory Syndrome Coronavirus-2 Infection: A Case Report

Abstract

Introduction: As the novel coronavirus pandemic continues to affect people worldwide, immune-mediated inflammatory syndromes related to this virus have been reported. SARS Coronavirus-2 infection disease (COVID-19) may accompany various cutaneous symptoms, such as viral exanthems or wheels. These symptoms may occur at the early course of the disease or after that. Cutaneous symptoms of COVID-19 usually have a favorable outcome. Case Presentation: We presented a rare case of inpatient COVID-19 pneumonia, who developed a purpuric rash, abdominal pain, and hematuria. His dermal histopathological study revealed small-vessel vasculitis. We diagnosed Henoch–Schoenlein purpura based on clinical and histopathological findings and treated him with intravenous dexamethasone followed by oral prednisolone. The purpuric rashes disappeared in two weeks. Conclusions: Cutaneous manifestation of COVID-19 is usually diffuse maculopapular rashes. Other presentations include vesicular rashes and acral cyanosis. Dermal histopathological study in most patients with COVID-19 who developed cutaneous symptoms revealed perivascular inflammation and microthrombus in some cases. Thus, COVID-19 should be considered in any patient with a new onset of cutaneous symptoms.
