A retroperitoneal xanthogranuloma was surgically removed, with partial resection due to adhesion. Follow-up imaging showed the remaining tumor mass gradually decreased in size.

Area of Science:

  • Urology
  • Oncology
  • Pathology

Background:

  • A 48-year-old male presented with lumbago.
  • Diagnostic imaging revealed a solid retroperitoneal tumor near the right renal hilus.

Observation:

  • The patient underwent surgical tumor resection and right nephrectomy.
  • Complete tumor removal was not possible due to adherence to the inferior vena cava and lumbar spine.

Findings:

  • Histological examination confirmed the diagnosis of retroperitoneal xanthogranuloma.
  • Post-operative imaging after one year demonstrated a spontaneous reduction in the size of the residual tumor mass.

Implications:

  • This case highlights the potential for spontaneous regression in retroperitoneal xanthogranulomas.

  • Further investigation may be warranted to understand the mechanisms behind tumor reduction.
