This study presents a rare case of incidental renal papillary carcinoma in a 76-year-old male, initially presenting as hydronephrosis. The findings revealed a synchronous metastasis in the ipsilateral ureter, highlighting a critical diagnostic consideration.
Area of Science:
- Urology
- Oncology
- Pathology
Background:
- Renal papillary carcinoma (RPC) is a subtype of renal cell carcinoma with varying prognoses.
- This report details an incidental finding of RPC in a 76-year-old male patient.
Observation:
- The patient presented with symptoms mimicking severe hydronephrosis.
- Diagnostic imaging revealed findings suggestive of an obstructive uropathy.
Findings:
- Pathological examination confirmed renal papillary carcinoma.
- A synchronous metastasis was identified in the ipsilateral ureter, a rare occurrence.
Implications:
- This case underscores the importance of considering RPC in the differential diagnosis of obstructive uropathy.
- The presence of ureteral metastasis highlights the aggressive potential of this tumor subtype and influences treatment strategies.
