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

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.

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.

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.
