Summary
A rare case of Wegener's granulomatosis presented as a destructive earlobe ulcer. Early diagnosis and treatment with immunosuppressants led to remission, preventing further organ damage.
Area of Science:
- Rheumatology
- Dermatology
- Otorhinolaryngology
Background:
- Wegener's granulomatosis (WG), now known as granulomatosis with polyangiitis (GPA), is a rare autoimmune vasculitis.
- Superficial forms of WG/GPA can present with diverse cutaneous and upper respiratory tract manifestations.
- Protracted superficial WG/GPA requires accurate diagnosis and tailored immunosuppressive therapy.
Observation:
- A 27-year-old woman developed a progressive, destructive ulcerated lesion on her right earlobe, resembling pyoderma gangrenosum.
- Associated symptoms included nasal congestion, rhinorrhea, and crusting, with similar nodules appearing on the face.
- Skin biopsy revealed suppurative granulomatous inflammation.
Findings:
- Antineutrophil cytoplasmic antibody (ANCA) testing was positive, with high specificity for proteinase-3 (PR3-ANCA).
- The clinical presentation and serological findings were consistent with protracted superficial Wegener's granulomatosis.
- Initial treatment with prednisone and azathioprine achieved complete resolution of lesions.
Implications:
- Prompt diagnosis and aggressive immunosuppressive therapy are crucial for managing superficial WG/GPA.
- Corticosteroid-sparing agents like methotrexate can be effective in maintaining remission.
- This case highlights the importance of considering WG/GPA in patients with unusual ulcerative and respiratory symptoms.
