PURPOSE: To evaluate the outcomes of surgical intervention and active surveillance in patients diagnosed with cystic renal cell carcinoma at our hypothesized radiologic cutoff of >50% cystic. MATERIALS AND METHODS: We identified all patients with a pathologically confirmed cystic renal mass that fit our criteria from 2000 to 2015 (n=430). Patients with lack of CT imaging, tumors <50% cystic on imaging, multifocal tumors and prior renal cell carcinoma were excluded (n=292)...

BACKGROUND: Renal cell carcinomas represent 85% of malignant renal tumors. Typically, the tumor remains asymptomatic a long time before the appearance of urologic clinical signs. In some cases, metastasis can precede the manifestations of the primary tumor. Different sites are potential metastatic localizations for renal tumors, including skull metastases who represent a very rare location. CASE DESCRIPTION: We report the case of a 65-year-old man presented after the appearance of a skull mass...

The germline BAP1 (BRCA1-associated protein-1) mutation and associated cancer pre-disposition syndrome was first described in 2011. Since then, physicians have considered this diagnosis for patients with a characteristic personal or family history of BAP1-associated tumours (mainly uveal and cutaneous melanoma, pleural/peritoneal mesothelioma, renal cell carcinoma and BAP1-deficient melanocytic lesions). However, a positive germline BAP1 mutation detection creates significant uncertainty in terms of appropriate cancer surveillance...

Eosinophilic solid and cystic renal cell carcinoma (ESC RCC) is a recently described entity with distinct clinical, pathological and molecular features. However, the radiologic aspects of ESC RCC have not been characterized. In this report, we describe the imaging findings of two ESC RCC's. We found two distinct imaging patterns that varied depending on histopathologic features (solid or cystic predominance). In conclusion, it is important to know the imaging characteristics and pathological correlation of this novel neoplasm to increase its recognition and improve the decision-making process...

INTRODUCTION: Provincial/territorial cancer registries (PTCRs) are the mainstay for Canadian population-based cancer statistics. Each jurisdiction captures this data in a population-based registry, including the Nova Scotia Cancer Registry (NSCR). The goal of this study was to describe data from the NSCR regarding renal cell carcinoma (RCC) pathology subtype and method of diagnosis and compare it to the actual pathology reports to determine the accuracy of diagnosis and histological subtype assignment...

INTRODUCTION AND OBJECTIVE: Renal tumor biopsy is recommended for histological diagnosis of radiologically indeterminate renal masses, to select patients with small-renal masses for surveillance approaches, before ablative treatments and to confirm metastatic spread of renal cell cancer (RCC), according to the EAU guidelines. We aimed to determine outcomes of patients with suspicious renal masses with initial finding of regular renal tissue in renal tumor biopsies. METHODS: Retrospective database analysis of 101 patients undergoing CT-guided-, percutaneous renal tumor biopsies in local anesthesia...

Intraosseous foreign body granuloma formation related to migrated surgical material is a rarely reported condition with variable imaging appearance. In this case report, we describe a foreign body granuloma that occurred in a lumbar vertebral body one level above a prior surgical fusion. The lytic appearance mimicked a skeletal metastasis in a 65-year-old patient with recently diagnosed renal cell carcinoma. To the best of our knowledge, this is the first reported case of a lumbar vertebral foreign body granuloma occurring distant from the site of surgery, indistinguishable from skeletal metastasis on radiologic examination...

PURPOSE OF REVIEW: To explore the role of molecular imaging in the characterization of renal masses. RECENT FINDINGS: Incidentally detected renal masses exhibit variable malignant potential related to their underlying histology. Patients presenting with a renal mass should undergo individual risk stratification including characterization of their tumor histology. At the present time, anatomical imaging techniques are unable to reliably distinguish between the various renal tumor subtypes...

Background: Renal anastomosing hemangioma (RAH) is an extremely rare benign vascular tumor first described in 2009. Making this diagnosis is fraught with challenges. Radiologically they share features consistent with renal cell carcinomas (RCCs). Their vascular nature poses risks if considering preoperative biopsy and histologically they share characteristics akin to angiosarcomas. The few reports published in the literature suggest presentation with hematuria, flank pain, and polycythemia although the majority are diagnosed at postnephrectomy histologic examination...

INTRODUCTION: Renal cell carcinoma (RCC) accounts for approximately 3% of adult malignancies and more than 90% of neoplasms arising from the kidney. Uninformative percutaneous kidney biopsies vary from 10 to 23%. As a result, 7.5-33.6% of partial nephrectomies in patients with small renal masses (SRM) are performed on benign renal tumors. The aim of this study was to assess the feasibility of the apparent diffusion coefficient (ADC) of the diffusion-weighted imaging (DWI) of MRI, as RCC imaging biomarker for differentiation of SRM...

PURPOSE: To evaluate the importance of preoperative neutrophil lymphocyte ratio (NLR) predicting malignancy in patients who undergo partial nephrectomy due to renal mass. MATERIALS AND METHODS: Seventy nine patients who underwent open partial nephrectomy for renal masses were included in this retrospective study. In preoperative routine blood tests, renal ultrasonography and contrast-enhanced computed tomography were performed for all patients. Preoperative neutrophil lymphocyte ratio were compared in patients with clear cell renal cell carcinoma (Group1, 65 patients) and benign lesions (Group 2, 14 patients)...

We report a case of a 65-year-old man examined for hematuria and neurologic symptoms. Radiologically a tumour of the kidney was suspected, with metastatic involvement of the brain and both lungs. The urologists then performed a cytoreductive nephrectomy.In histopathological examination of the nephrectomy specimen a clear cell renal cell carcinoma (clear cell RCC) was found. However, an additional focus of a high-grade adenocarcinoma was discovered that turned out to be a metastasis of a poor differentiated lung adenocarcinoma...

Incidental Renal Cell Carcinoma (RCC) can be found in a tubercular kidney; however, the vice versa i.e., finding tubercular lymphadenopathy after radical nephrectomy for cancer is exceptionally rare. To the best of our knowledge, only two cases of coexistent renal cell carcinoma and tubercular paraaortic lymphadenopathy have been reported till date. Out of these, only one case was of papillary renal cell carcinoma. We hereby, report a rare case of papillary renal cell carcinoma with coexisting paraaortic tubercular lymphadenopathy, which was upstaged based on radiology findings...

The success of targeted therapies, including inhibitors of the vascular endothelial growth factor pathway or the mammalian target of rapamycin, in the treatment of metastatic renal cell carcinoma led to interest in testing their efficacy in the adjuvant setting. Results from the first trials are now available, with other studies due to report imminently. This review provides an overview of adjuvant targeted therapy in renal cell carcinoma, including interpretation of currently available conflicting data and future direction of research...

Although the second most common malignancy after urothelial carcinoma, squamous cell carcinoma (SCC) of the renal pelvis is a rare entity. It has strong association with nephrolithiasis thus emphasizing prompt treatment of renal calculi. Because of rarity and nonspecific clinical and radiological findings, it mostly presents at pT3 or higher stage. We report SCC of renal pelvis that was missed two times on non-contrast CT scans and was diagnosed incidentally in a nephrectomy specimen. Its prognosis is similar to that of urothelial carcinoma of comparable stage...

BACKGROUND: Sinonasal renal cell-like carcinoma (SRCLC) is an extremely rare low malignant tumor arising in the sinonasal tract, with histological mimicry of renal cell carcinoma. CASE PRESENTATION: We present a case of sinonasal renal cell-like carcinoma in a 63-year-old male patient. Computer tomography(CT) scanning revealed a soft tissue mass at the left nasal cavity and choana. Histologically, the predominant tumor architecture was follicular to glandular with intervening fibrous septa...

This is a 15-year-old female who presented with sudden onset left flank pain associated with nausea and vomiting and a history of weight loss. Radiological investigation revealed a large non-obstructive tumor involving the lower pole of the left kidney which was primarily thought to be a renal cell carcinoma. She underwent left open radical nephrectomy with adrenalectomy. Histopathology of the resected specimen showed features of Ewing's sarcoma of the kidney which was confirmed by cytogenetic analysis. This is a rare disease especially in the pediatric group and in reporting such a rare case we hope it helps in identifying a potential course of the disease and its response to the involved treatment...
