[Synchronous squamous cell XXXX and @entity957 : report of two cases and review of literature].

@entity1 @entity8 @entity1901 @entity1698 @entity5 @entity957 @entity812 @entity1358 @entity490 @entity3 @entity811 @entity703
OBJECTIVE: To study the clinicopathological characteristics of @entity957 (SCC) of the renal pelvis and SCC of the ureter. METHODS: The clinical data of two cases of @entity1358 and SCC of the ureter were retrospectively reviewed and analyzed. In case 1, a 68-year-old @entity1 with @entity811 for a month, imaging modalities revealed a right @entity703 and a right distal @entity1698 . The @entity1 underwent nephroureterectomy and excision of the bladder cuff. Case 2, a 60-year-old @entity1 with the complaint of lower @entity490 and @entity812 for a month, was diagnosed as @entity1901 in another hospital. Ureterolithotomy was performed and a @entity5 was found at the lower site of the stone intraoperatively. The pathological report demonstrated SCC, and the @entity1 was transferred to our hospital for further treatment. We found a left renal mass invading the left hemicolon during surgery, and nephroureterectomy was performed with a bladder cuff excision, left hemicolon resection, and also complete lymph node dissection. Neither of @entity1 received adjuvant radiotherapy/chemotherapy. RESULTS: Moderately differentiated SCC was reported in both of @entity8 in case 1 and the @entity5 invaded the subepithelial connective tissue in the renal pelvis and superficial muscle in the ureter. In case 2, moderately differentiated @entity1358 with colon @entity3 and poorly differentiated SCC of the ureter was reported with two retroperitoneal lymph node @entity3 . The two @entity1 died from @entity5 recurrence and @entity3 5 and 6 months after the surgery, respectively. CONCLUSION: Synchronous SCC of the renal pelvis and SCC of the ureter are rare and has high likeliness of early recurrence and @entity3 , often with poor prognosis.
