INTRODUCTION: The increasing use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology to examine pancreatic neoplasms has led to an increase in the diagnosis of metastases to the pancreas. Renal cell carcinoma (RCC) is the most common metastasis to the pancreas. Our study examines 33 cases of metastatic RCC to the pancreas sampled by EUS-FNA from four large tertiary care hospitals. MATERIALS AND METHODS: We searched the cytopathology database for RCC metastatic to the pancreas diagnosed by EUS-FNA from January 2005 to January 2015...

BACKGROUND: Historically, local control of recurrent sarcomas has been limited to radiotherapy when surgical re-resection is not feasible. For metastatic carcinomas to the bone or soft tissue, radiotherapy and some interventional radiology treatment along with other systemic therapies have been widely advocated due to the possibility of disseminated disease. These techniques are effective in alleviating pain and achieving local control for some tumor types, but it has not been effective for prolonged local control of most tumors...

BACKGROUND: The aim of this study was to investigate the diagnostic accuracy of contrast-enhanced computed tomography (CT) and contrast-enhanced magnetic resonance imaging (MRI) of small renal masses in real practice. METHODS: Contrast-enhanced CT and MRI were performed between February 2008 and February 2013 on 68 patients who had suspected small (≤4 cm) renal cell carcinoma (RCC) based on ultrasonographic measurements. CT and MRI radiographs were reviewed, and the findings of small renal masses were re-categorized into five dichotomized scales by the same two radiologists who had interpreted the original images...

Xanthogranulomatous pyelonephritis is an uncommon inflammatory condition accounting for 1% of chronic pyelonephritis cases. Clinically and radiologically it mimics other renal space occupying lesions. Hence, correct preoperative diagnosis is not possible in all cases and nephrectomy is done in most patients. Renal tubulopapillary adenomas are benign epithelial lesions of kidney found to be associated with papillary renal cell carcinoma, acquired renal cystic disease, long term hemodialysis, arteriosclerotic renal vascular disease, etc...

AIM: Papillary renal cell carcinoma type 1 (pRCC1) represents the second most common type of malignant renal epithelial tumour. The origin of its characteristic appearance, its growth mechanism, and the long-term efficiency of its surgical treatment remain uncertain. Our aim was to determine typical characteristics of surgically treated pRCC1. METHODS: pRCC1 was verified in 83 of 1,629 (5.1%) kidney tumours surgically treated in the period of January 2007-January 2016...

Epithelioid angiomyolipoma is a rare form of potentially malignant angiomyolipoma, recently considered separate entity by the World Health Organization classification of renal tumors. This lesion poses a problem in differential diagnosis with clear cell carcinomas. There are no clinical or radiological specific criteria that characterize this tumor. Immunohistochemistry revealing epithelioid cells with positive HMB45 marker is essential for diagnosis. Treatment should be discussed during the multidisciplinary consultation...

Tuberculosis can involve any part of the body. Urogenital tuberculosis is a fairly common extra-pulmonary manifestation of tuberculosis and renal tuberculosis is the most common form of urogenital tuberculosis. Renal tuberculosis seldom presents as a mass, usually due to hydronephrosis of the involved kidney. However in extremely rare cases it may present as an inflammatory pseudotumor which may mimic renal cell carcinoma. We present a case of a 65- year- old male who was provisionally diagnosed as renal cell carcinoma based on clinical and radiological findings and managed accordingly but was finally diagnosed as renal tuberculosis based on histopathological examination of surgical specimen...

Transradial access is being used with increasing frequency for interventional radiology procedures and offers several key advantages, including decreased access site complications and increased patient comfort. We report the technique of using transradial access to perform preoperative embolization of a humeral renal cell carcinoma metastasis and pathologic fracture. A transradial approach for performing humeral preoperative tumor embolization has not been previously reported, to our knowledge. In the appropriately selected patient, this approach may be safely used to perform upper extremity embolization...

Renal adenomatosis is a rare disease characterized by numerous adenomas in bilateral kidneys. A literature review shows that malignant tumors can arise in this condition. The present case describes an oncocytic papillary renal cell carcinoma (PRCC) arising in renal adenomatosis. A 70-year-old man presented with incidentally identified, multiple right renal masses on computed tomography. Right nephrectomy was performed, and the resected kidney revealed numerous radiologically undetected small nodules additionally...

BACKGROUND: Renal cancer may invade the inferior vena cava (IVC) creating more complex surgical intervention. We investigate radiologic findings that may predict vascular reconstruction prior to surgery and future renal cancer-specific mortality. MATERIALS AND METHODS: Radiologic findings included Mayo Clinic risk factors for vascular reconstruction: Right-sided tumor, anteroposterior diameter of the IVC at the ostium of the renal vein ≥24.0 mm, and radiologic identification of complete occlusion of the IVC...

Primary renal leiomyosarcomas are rare, aggressive tumors. They constitute 1-2% of adult malignant renal tumors. Although leiomyosarcomas are the most common histological type (50-60%) of renal sarcomas, information on renal leiomyosarcoma is limited. Local or systemic recurrences are common. The radiological appearance of renal leiomyosarcomas is not specific, therefore renal leiomyosarcoma cannot be distinguished from renal cell carcinoma by imaging methods in all patients. A 74-year-old female patient presented to our clinic complaining of a palpable mass on the right side of her abdomen in November 2012...

In the United States during the year 2015, approximately 61,560 patients are expected to be diagnosed with kidney cancer and 14,080 to die from the disease. We present the case of a patient with renal cell carcinoma who suffered severe perioperative bleeding and coagulopathy after emergency sternotomy. We also engage in relevant aspects of perioperative anesthesia care including the considerations and management of coagulopathy, liver failure and renal failure in the oncologic patient. The case is a 49-year-old man with vena cava tumor thrombus who underwent radiologic tumor embolization, left radical nephrectomy, and inferior vena cava (IVC) thrombectomy...

BACKGROUND: Xanthogranulomatous pyelonephritis (XGP) is a rare renal tumor that arises as a complication of chronic obstructive pyelonephritis of uncertain etiology. It is primarily an adult tumor seen occasionally in children associated with urinary tract obstruction due to congenital urological anomalies, nephrolithiasis, and recurrent urinary tract infections. Radiologically, it may show neoplastic features such as those seen in common pediatric renal malignancies like wilms' tumor and renal cell carcinoma...

Renal oncocytoma is one of the most unusual benign lesion, which are usually diagnosed postoperatively, since their differentiation from renal cell carcinoma is challenging. The present study reports two cases of renal oncocytoma in a 60-year-old woman and a 46-year-old man. Relevant clinical and pathological data on the two patients were retrieved. The tumors were excised and the patients underwent laparoscopic radical nephrectomy. Typical features of oncocytoma were observed upon histological examination of the excised specimens...
