BACKGROUND: Extra-adrenal paragangliomas (PGLs) are infrequent, benign, and neuroendocrine tumors arising from chromaffin cells of the autonomic nervous system. Most PGLs are sporadic, but up to 32% are associated with inherited syndromes such as neurofibromatosis type 1, von Hippel-Lindau disease, and familial PGL. Although most PGLs develop above the umbilicus, they have been reported in the genitourinary (GU) tract. Owing to the paucity of literature on the rates of GU PGL, the objective of our study is to describe the demographic, pathologic, and clinical characteristics of GU PGL, and compare them to non-GU sites of PGL using the surveillance, epidemiology, and end results (SEER) database...

BACKGROUND: Thyroid metastases to distant sites are uncommon incidents, most often metastasizing to the lungs and bones. Rates of metastasis to the kidney are particularly low, ranging from 2.8-3.8% for papillary and 6-20% for follicular variants of well-differentiated thyroid cancers (WDTCs). In rare instances, tumor-to-tumor metastasis between two true primary neoplasms can occurs. This medical phenomenon has previously occurred as a clear cell renal cell carcinoma (CCRCC) spreading to a WDTC...

BACKGROUND: Late pulmonary metastasis from urothelial carcinoma (UC) of the upper urinary tract is extremely rare. CASE PRESENTATION: A 76-year-old man was referred to our hospital due to an abnormal shadow on chest X-ray. He had a history of left nephrectomy with a diagnosis of UC in the renal pelvis 29 years previously. Computed tomography showed a mass lesion in the right middle lobe of the lung that measured 4.9 cm in diameter. A transbronchial biopsy revealed the tumor to be metastatic pulmonary UC, and he underwent right middle lobectomy of the lung...

Kidney ultrasound is one of the basic procedures in the practice of a urologist. Apart from the location and the size, description of renal morphology should contain the thickness of the anterior lip parenchyma in a transverse section and the location of possible narrowings. Uneven outline of the kidney is a sign of past inflammatory conditions. In the case of the pelvicalyceal system dilation, it is advised to specify the dimensions of the pelvis and calyces. Convex shape of the calyces proves elevated pressure within the pelvicalyceal system...

Indications and techniques of lymph node dissection (LND) for upper tract urothelial carcinoma (UTUC) are still controversial. Areas covered: In this study, a systematic review of the English-language literature was performed up to 1 July 2016 using the Medline, Scopus, Cochrane Library and Web of Sciences databases to provide a detailed overview of the most commonly dissected surgical templates of LND for UTUC according to laterality and location of the tumor. Overall, sixteen studies were analyzed. Based on the shared experiences in the scientific literature, the LND template typically included: for right-sided tumors of the renal pelvis, upper third and middle third of the ureter, the renal hilar, paracaval, precaval and retrocaval nodes, while for left-sided tumors the renal hilar, paraaortic and preaortic nodes...

BACKGROUND: Cancers are heterogeneous comprising of distinct tumor subtypes. Therefore, presenting the burden of cancer in the population and trends over time by these tumor subtypes is important to identify patterns and differences in the occurrence of these subtypes, especially to generalize findings to the US general population. METHODS: Using SEER cancer registry data, we present incidence rates according to subtypes for diagnosis years (1992-2013) among men and women for five major cancer sites: breast (female only), esophagus, kidney and renal pelvis, lung and bronchus, and thyroid...

Renal cell carcinoma (RCC) is the most common malignancy of the kidney. It is not commonly form tumor thrombus in the ureter or renal pelvis. A 29-year-old woman presented with asymptomatic gross hematuria. Contrast CT study revealed a tumor suspected to be a Transitional Cell Carcinoma (TCC). However, tumor thrombus was found in the renal pelvis and ureter. We performed Nephroureterectomy, bladder cuff excision, and lymph node dissection, and the tumor was diagnosed histopathologically as RCC. We report a very rare case of thrombus-like tumor of renal cell carcinoma mimicking transitional cell carcinoma of kidney...

Pleomorphic Hyalinizing Angiectatic Tumor (PHAT) is a rare benign lesion characterized by slow growth, infiltrative behavior and high rate of local recurrences. Only one case has been described in retroperitoneum, at renal hilum, but not involving pelvis or parenchyma. Here we present the first case of PHAT arising in the renal parenchyma. A nodular lesion in right kidney lower pole was diagnosed to a 61 year old woman. The patient underwent right nephrectomy. Microscopically, the lesion showed solid and pseudo-cystic components with hemorrhagic areas characterized by aggregates of ectatic blood vessels...

Cancer related to hereditary syndromes corresponds to approximately 5-10% of all tumors. Among those from the genitourinary system, many tumors had been identified to be related to genetic syndromes in the last years with the advent of new molecular genetic tests. New entities were described or better characterized, especially in kidney cancer such as hereditary leiomyomatosis renal cell carcinoma (HLRCC), succinate dehydrogenase kidney cancer (SDH-RCC), and more recently BAP1 germline mutation related RCC...

Primary malignant tumors of the renal pelvis are relatively rare. Urothelial carcinoma of renal pelvis accounts for 7% of all renal neoplasms, with Squamous Cell Carcinoma (SCC) forming a very small percentage of these cases. Urothelial and SCC of renal pelvis is still a rarer entity. This malignancy of the renal pelvis lacks the characteristic presentation of common renal cell carcinoma and usually presents at an advanced disease stage. We report a case of urothelial and SCC of renal pelvis in a 61-year-old male who presented with non-specific clinical complaints like dysuria and right flank pain...

Metastatic lesions of the acetabulum can be painful and debilitating. First-line treatment is multimodal and consists of disease-specific chemotherapy, osteoclastic inhibitors, analgesics, and radiation therapy. When these therapies fail, surgical intervention usually is indicated and varies from regional defect stabilization to large periacetabular reconstructions that are demanding procedures with high rates of complications. Percutaneous cement augmentation (acetabuloplasty) of lesions in selected patients has been explored as a less invasive method of lesional control...

Totally 85 patients with 93 renal lesions who underwent contrast-enhanced ultrasound (CEUS) were retrospectively studied with quantitative analysis to evaluate its value in the differential diagnosis of renal tumor histotypes. CEUS characteristics were analysed including the enhancement patterns, peak intensity, homogeneity of enhancement, and pseudocapsule. Quantitative parameters of peak intensity (P) and time to peak (TP) were measured with QontraXt software, and the index "relative enhancement percentage" ΔP% and "difference in TP between tumor and cortex" ΔTP were used to quantify the CEUS features of renal tumors...
