An unusual renal angiomyolipoma without significant fat was diagnosed in a young woman, presenting with lymph node involvement. This rare presentation challenges typical diagnostic criteria for renal tumors.

Area of Science:

  • Nephrology
  • Oncology
  • Pathology

Background:

  • Renal angiomyolipomas are typically benign tumors composed of fat, smooth muscle, and vascular elements.
  • Incidental renal masses are increasingly detected via imaging, necessitating accurate diagnosis.

Observation:

  • A 25-year-old asymptomatic woman presented with an incidentally discovered renal mass and adenopathy.
  • Initial computed tomography and ultrasonography suggested a malignant neoplasm due to the mass and enlarged lymph nodes.

Findings:

  • Pathological examination revealed a renal angiomyolipoma with minimal fat content.
  • The tumor demonstrated lymph node involvement, an atypical feature for renal angiomyolipoma.

Implications:

Related Experiment Videos

  • This case highlights the importance of considering atypical presentations of renal angiomyolipoma, even when imaging suggests malignancy.
  • The findings underscore the need for thorough pathological examination to differentiate benign from malignant renal masses.
  • Unusual angiomyolipoma presentations can mimic advanced malignancies, impacting diagnostic and treatment strategies.
