Summary
Xanthogranulomatous pyelonephritis can mimic renal cell carcinoma, presenting diagnostic challenges. This case highlights the importance of histopathology in differentiating these conditions.
Area of Science:
- Nephrology
- Pathology
- Radiology
Background:
- Xanthogranulomatous pyelonephritis (XGP) is a rare, chronic granulomatous infection of the kidney.
- It can present with non-specific symptoms, mimicking other renal pathologies.
Observation:
- A 63-year-old female presented with prolonged fever and right lumbar pain.
- Imaging revealed a heterogeneous renal mass, and biopsy suggested renal cell carcinoma.
- The patient underwent radical nephrectomy for suspected malignancy.
Findings:
- Histopathological examination confirmed focalized stage II xanthogranulomatous pyelonephritis.
- No evidence of neoplasia was found, despite initial diagnostic indicators.
Implications:
- Xanthogranulomatous pyelonephritis poses significant diagnostic challenges due to its potential to mimic renal neoplasia.
- Accurate diagnosis relies on definitive histopathological analysis to guide appropriate management.
