We report the first case of proteinase 3-antineutrophil cytoplasmic antibody-positive granulomatosis with polyangiitis (GPA) with predominant ears, nose, and throat manifestations following coronavirus disease 2019 (COVID-19) vaccination. A 63-year-old woman presented with aural fullness 3 days after vaccination. She presented with progressive rhinosinusitis and otitis media leading to profound hearing loss within 3 weeks. Clinical imaging revealed soft-tissue shadows in the paranasal sinuses with multiple pulmonary nodules, and histopathology was consistent with a diagnosis of GPA. It is crucial to be wary of the possibility of GPA in patients who received COVID-19 vaccines due to its rapid disease progression.
