AbstractBackground and objectives: The initial symptom that triggers granulomatosis with polyangiitis (GPA) diagnosis is rarely ocular. We describe a case with a single ocular lesion identified as probable GPA due to proteinase 3 (PR3)-antineutrophil cytoplasmic antibody (ANCA)-positivity according to the diagnostic criteria of the Ministry of Health in Japan; the lesion repeatedly worsened. Materials and methods: A 25-year-old female visited the Department of Ophthalmology, Asahi General Hospital, with upper eyelid swelling and conjunctival and episcleral hyperemia of the left eye. Both hordeolum and eyelid cellulitis were suspected, as the condition was resistant to treatment with antibiotic eye drops. Episcleritis was suspected due to localized hyperemia in the upper part of the eye. Upon treatment with antibacterial agents and steroid eye drops, the swelling and the hyperemia repeatedly worsened every week. Results: Blood samples were positive for PR3-ANCA, and GPA with an isolated ocular lesion was considered. After oral steroid treatment, the patient had no recurrence for 4 years. There was no systemic involvement in the upper respiratory tract, lungs, or kidneys. Conclusions: Diagnosing GPA with ocular symptoms as initial manifestations is challenging. GPA should be considered in treatment-resistant eyelid, orbital, and episcleral lesions, even at a young age.
