Summary
This case study presents bilateral renal metanephric adenoma, a rare kidney tumor, found in a hypertensive patient with microscopic hematuria. Surgical intervention was performed, confirming the benign nature of the tumors.
Area of Science:
- Nephrology
- Oncology
- Pathology
Background:
- Metanephric adenoma is a rare, benign renal neoplasm.
- Bilateral occurrence is exceptionally uncommon.
- Often presents incidentally or with vague symptoms like hematuria or hypertension.
Observation:
- A 51-year-old patient presented with hypertension and microscopic hematuria.
- Bilateral renal masses were identified: a large left tumor (60 mm) and a smaller right tumor (11 mm).
- The left tumor significantly protruded into the renal pelvis.
Findings:
- Histological examination confirmed benign metanephric adenoma in both kidneys.
- The left tumor required radical nephrectomy due to its size and pelvic involvement.
- The right tumor was treated with lumpectomy.
Implications:
- This case highlights the importance of thorough investigation for rare renal tumors, even with common presenting symptoms.
- Management strategies for bilateral metanephric adenoma should consider tumor size, location, and potential for malignancy.
- Further research into the etiology and optimal management of metanephric adenoma is warranted.
