Wegener granulomatosis presenting as renal mass

Area of Science:

• Nephrology
• Rheumatology
• Oncology

Background:

• Wegener granulomatosis (WG) is a systemic vasculitis affecting multiple organs.
• While WG commonly impacts the respiratory and genitourinary tracts, renal involvement is typically focal.
• Unusual presentations of WG, such as renal masses, are infrequently documented.

Observation:

• A case of Wegener granulomatosis presenting as a distinct renal mass is described.
• The diagnosis was clinically suspected but not confirmed prior to surgical intervention.
• The patient underwent nephrectomy and received chemotherapy.

Findings:

• The patient's condition significantly improved following treatment.
• Cyclophosphamide and prednisone were utilized in the chemotherapy regimen.
• The patient was discharged in stable condition after management.

Implications:

• This case highlights the importance of considering rare presentations of Wegener granulomatosis.
• It underscores the potential for WG to manifest as a renal mass, mimicking other pathologies.
• Successful management involving surgery and chemotherapy demonstrates effective therapeutic strategies for such cases.
