    Area of Science:

    • Uropathology
    • Nephrology
    • Granulomatous diseases

    Background:

    • Xanthogranulomatous pyelonephritis (XGP) is a rare, chronic inflammatory condition of the kidney.
    • Xanthogranulomatous ureteritis (XGU) is an even rarer variant affecting the ureter.
    • Understanding the clinicopathological spectrum of these conditions is crucial for diagnosis and management.

    Observation:

    • A case of xanthogranulomatous ureteritis is presented.
    • The patient exhibited symptoms consistent with xanthogranulomatous pyelonephritis, including chronic urinary tract infection, weight loss, urinary obstruction, pyuria, and gram-negative bacteriuria.
    • The ureteral lesion presented as a yellowish, granulomatous nodule.

    Findings:

    • Histological examination revealed foamy histiocytes with periodic acid-Schiff (PAS)-positive cytoplasmic granules, characteristic of xanthogranulomatous inflammation.

    Related Experiment Videos

  • The ureteral lesion mimicked a neoplastic obstruction or a specific granuloma.
  • The findings underscore the similarities in presentation between XGU and XGP.

    • Implications:

    • This case expands the understanding of xanthogranulomatous diseases affecting the urinary tract.
    • Recognizing the similarities between XGU and XGP can aid in differential diagnosis.
    • Further research into the pathogenesis and optimal treatment of XGU is warranted.
