Asymptomatic ureteral metastasis of chromophobe renal cell carcinoma after radical nephrectomy: A case report and review of literature.

Introduction: Standard treatment for renal cell carcinomas (RCCs) is radical/partial nephrectomy and unlike upper urothelial carcinoma, complete ureteral removal is not necessary nor is advised in RCCs as tumor recurrence in ureteral remnant has scarcely been reported. Here, we present a rare case of chromophobe RCC (ChRCC) metastasis in remnant ureter following radical nephrectomy and perform a literature review in this regard.

Case Presentation: A 66-year-old man presented with a CT scan-as a surveillance protocol imaging- showing a mass in ipsilateral remnant ureter 9 months after radical nephrectomy due to ChRCC while being completely asymptomatic.

Solitary vertebral metastasis of unknown primary renal cell carcinoma treated with surgical resection plus tyrosine kinase inhibitor: A case report.

Introduction: Although 25-30 % of renal cell carcinomas (RCC) might be diagnosed in metastatic stage, occurrence of metastatic renal cell carcinoma (mRCC) as a cancer of unknown primary site (CUP-mRCC) is extremely rare. Here, we present a case of vertebral mass causing radicular pain that has been diagnosed to be mRCC through core needle biopsy while no renal mass has been found during serial imaging.

Case Presentation: A 60-year-old woman presented with severe lumbar pain radiating to left leg.

Malignant rhabdoid tumor of kidney in an adult patient with positive family history of rhabdoid tumor: A case report and review of literature.

Introduction And Importance: Malignant rhabdoid tumor of kidney (MRTK) is almost exclusive to children. Only 10 cases of adult MRTK have been reported. Here, we present a case of MRTK in an adult patient and discuss its clinical findings, diagnostic challenges, and treatment outcome.

Migration of nephrostomy tube into right atrium during percutaneous nephrolithotomy: A case report.

Introduction And Importance: Percutaneous nephrolithotomy (PCNL) is one of the most commonly performed surgeries in urology. Due to blind nature of the procedure unexpected events are inevitable. Misplacement of percutaneous nephrostomy (PCN) during PCNL into the venous system is one of the rarest complications causing great stress to both physician and the patient.

Cushing's syndrome as a paraneoplastic feature of renal cell carcinoma: A case report.

Cushing's syndrome has been believed to be a paraneoplastic syndrome of renal cell carcinomas. However, there appears to be a dearth of compelling evidence to substantiate this notion. The only eligible documentation of Cushing's syndrome due to ectopic adrenocorticotropic hormone secretion by renal cancer in English literature dates back to 1988, and it pertains to a deceased patient discovered during an autopsy.
