Pathologically diagnosed incidentaloma transition cell carcinoma (TCC) of renal pelvis in a laproscopic radical nephrectomy specimen done for a lower pole renal mass

Abstract

We are reporting a very rare case in the current era of modern diagnostics of an incidentally detected Transitional Cell Carcinoma(TCC) renal pelvis, detected pathologically when Right laparoscopic radical nephrectomy specimen of lower pole mass(RCC) was processed, with no prior suspicion of TCC clinically or pre-operative imaging. A 75-year-old female with 4 × 4cm strongly enhancing lower pole renal mass on CTscan underwent a Laparoscopic Radical Nephrectomy. Surprisingly histopathological examination revealed a focus of low-grade TCC, arising from renal pelvis, completely separate from lower pole mass which was a clear cell RCC.

Chromophobe renal cell carcinoma with ipsilateral ureteral urothelial carcinoma: A case report

“…Patients with papillary RCC combined with UCC had a shorter history of ~1 month, with the average maximum diameter of the kidney tumor being ~2 cm and the average maximum diameter of the ureteral tumor being ~2 cm. Patients with clear cell RCC combined with UUC had the second longest history, ~2 months, with an average maximum diameter of ~3 cm for renal tumours and 4 cm for ureteral tumours; patients with CRCC combined with UCC had a longer history, >3 months on average, with an average maximum diameter of ~4 cm for renal tumours and 5 cm for ureteral tumours (Table I) (12)(13)(14)(15)(16). Although the early symptoms of simple kidney cancer are not obvious, and even ~50% of the patients have no discomfort (17).…”
