Summary
This case report details a rare Bellini duct carcinoma of the kidney. Prompt diagnosis and treatment, including nephroureterectomy and M-VAC chemotherapy, led to successful outcomes for this rare renal tumor.
Area of Science:
- Uro-oncology
- Renal pathology
- Surgical oncology
Background:
- Bellini duct carcinoma is a rare subtype of renal cell carcinoma, originating from the collecting ducts.
- Early detection and accurate diagnosis are crucial for effective management of renal pelvic tumors.
Observation:
- A 53-year-old male presented with a suspected right renal pelvic tumor.
- Imaging studies (RP, CT, MRI) revealed a 2 cm space-occupying lesion involving the renal parenchyma and pelvis.
- Gross examination showed a white tumor with hemorrhagic necrosis in the upper pole.
Findings:
- Histological examination confirmed Bellini duct carcinoma, papillary type.
- Transitional cell carcinoma was initially suspected based on frozen section pathology.
- The patient underwent right nephroureterectomy.
Implications:
- Adjuvant M-VAC chemotherapy (Methotrexate, vinblastine, doxorubicin, cisplatin) was administered post-surgery.
- This case highlights the importance of accurate pathological diagnosis for guiding treatment.
- The patient remains disease-free, demonstrating the efficacy of multimodal treatment for this rare malignancy.
