Abstract
A 36-year-old man with moderate-to-severe left neck pain, local swelling, and tenderness was seen at the emergency room. Over the prior 4 days he had received beta-lactam antibiotic therapy with no improvement. One month before he experienced mild symptomatic coronavirus disease 2019 (COVID-19). The PCR-based test performed at the emergency room was still positive. The remaining personal history was negative. The routine laboratory parameters were within reference range and autoimmunity screening results were negative (Table 1).
