Summary
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:
- 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.
