Background:
Acute hemorrhagic edema of infancy (AHEI) is a small-vessel leukocytoclastic vasculitis, presented with low-grade fever and edema in the face and upper and lower limbs, as well as purpuric/ecchymotic lesions in these regions. AHEI was also reported after viral infections, including herpes simplex virus, rotavirus, and adenovirus. Case Presentation. Herein, we reported a case of a 20-month-old boy presented with low-grade fever. Additionally, mild cough and progressive purpuric/ecchymotic lesions were observed in some independent regions and extremity swelling. Laboratory testing showed leukopenia, lymphopenia, and the elevation of both C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Thereafter, the result of the reverse-transcriptase polymerase chain reaction (RT-PCR) test on the obtained specimen samples, including nasopharyngeal swab for COVID-19, was positive. The patient was treated with supportive care, and two weeks later, the serology test for COVID-19 resulted positive.
Conclusion:
We should think about children infected with COVID-19, particularly those with skin manifestations.
