Uterine fibroids (leiomyomas) are the most common benign neoplasm of the female pelvis and have a lifetime prevalence exceeding 80% among African American women and approaching 70% among Caucasian women. Approximately 50% of women with fibroids experience symptoms which may include menorrhagia that may result in anemia, bulk symptoms with bladder and bowel dysfunction and abdominal protrusion, dysmenorrhea, and infertility. Hysterectomy remains the most common treatment option for fibroids and concerns have been raised about the overuse of this procedure...

Post-transplant lymphoproliferative disorder (PTLD) occurs in ~5% of solid organ and hematopoietic stem cell transplant recipients. We report a unique presentation of PTLD in the bladder of a lung transplant recipient. Our patient was a 62-year-old female who received a bilateral lung transplant for chronic obstructive pulmonary disease. She presented with fever, left-sided flank pain and foul-smelling urine consistent with urosepsis. An abdominal and pelvic computerized tomography revealed an irregular and nodular bladder wall thickening suspicious for urothelial neoplasm...

Carcinosarcomas of the urinary bladder are rare biphasic neoplasms, consisting of both malignant epithelial and malignant mesenchymal components, and the prognosis of this tumor is unfavorable in most patients with even possibility of resection of disease. A 77-year-old male with a history of transurethral resection (TUR) of urothelial carcinoma (UC) of the bladder and adjuvant intravesical chemotherapy with pirarubicin 10 years ago revisited our department with a gross hematuria. Cystoscopy demonstrated an approximately 2...

Current non-invasive approaches for detection of urothelial cancers are suboptimal. We developed a test to detect urothelial neoplasms using DNA recovered from cells shed into urine. UroSEEK incorporates massive parallel sequencing assays for mutations in 11 genes and copy number changes on 39 chromosome arms. In 570 patients at risk for bladder cancer (BC), UroSEEK was positive in 83% of those who developed BC. Combined with cytology, UroSEEK detected 95% of patients who developed BC. Of 56 patients with upper tract urothelial cancer, 75% tested positive by UroSEEK, including 79% of those with non-invasive tumors...

Small cell carcinomas (SCCs) are aggressive neoplasms commonly associated with a pulmonary origin. However, albeit rare, extrapulmonary SCC can occur in a variety of sites with an incidence in North America approximated to be 0.1% to 0.4%. Among these sites, approximately 10% of extrapulmonary SCC cases occur in the prostate and are associated with a poor mortality with a median survival of 10 months. Because of the rarity of the prostatic SCC, there is no formal treatment protocol. In this case report, we present a patient who was diagnosed with SCC in the prostate as primary origin...

The inflammatory myofibroblastic tumor (IMT) is a rare lesion of unclear etiology and variable clinical course, consisting of a proliferation of fibroblasts and myofibroblasts, mixed with inflammatory cells. Synonyms of IMT are inflammatory pseudotumor and plasma cell granuloma reflecting the alleged inflammatory nature attributed to this lesion, even though this heterogeneity in the disease denomination is probably involved in a dispersion of the literature data. Among primary pulmonary neoplasms, it represents the most frequent endobronchial tumor of childhood and beyond the lung it has been described mainly in the bladder, mediastinum and mesentery...

Neuroendocrine bladder cancer is a relatively rare but often lethal malignancy, with cell of origin, oncogenomic architecture and standard treatment poorly defined. Here we performed comprehensive whole-genome and transcriptome sequencing on a unique cohort of genitourinary neuroendocrine neoplasms, mainly small cell carcinomas of the urinary bladder. The mutational landscape and signatures of neuroendocrine bladder cancer strikingly resembled those in conventional urothelial carcinoma, along with typically mixed histologies, supporting a common cellular origin...

Perivascular epithelioid cell tumor (PEComa) is an uncommon tumor which presents with epithelioid and spindled cell morphology and is immunoreactive for myogenic and melanocytic markers. Recently, a subset of PEComas has been reported to harbor TFE3 gene rearrangement.In this case report, we describe a TFE3 -expressing primary bladder PEComa in a 27-year-old male patient with acute myeloid leukaemia in remission. The tumor displayed epithelioid morphology with surrounding delicate blood vessels and was devoid of a prominent spindle cell component...

INTRODUCTION: Clear cell sarcoma of the kidney (CCSK) is childhood neoplasm with its own distinctive pattern of metastasis and may appear after a disease free interval of 5 years or more. MATERIALS AND METHODS: Histopathology and immunohistochemistry were available from the radical nephrectomy and the later partial cystectomy, which was performed after a seven disease-free interval. RESULTS: The pathologic features of the primary tumor were those of a classic CCSK with a monotypic pattern of uniform rounded to ovoid tumor cells with a background network of delicate blood vessels...

Inflammatory myofibroblastic tumor (IMT) is a neoplasm of intermediate malignant potential that only rarely involves the gynecologic tract. Several cases of IMT arising in various locations including the lung, bladder, trachea, and breast in association with pregnancy have been reported in the literature, and 3 cases involving the placenta have been previously described. We report 2 cases of IMT identified in association with pregnancy; the first was an intrauterine mass delivered entirely separate from the placenta and fetus, and the second was an incidental mass identified within the placental parenchyma following delivery...

Identification of FDGavid- neoplasms may be obscured by high-uptake normal tissues, thus limiting inferences about the natural history of disease. We introduce a FDG-PET radiomics tissue classifier for differentiating FDGavid- normal tissues from tumor. Thirty-three scans from 15 patients with Hodgkin lymphoma and 68 scans from 23 patients with Ewing sarcoma treated on two prospective clinical trials were retrospectively analyzed. Disease volumes were manually segmented on FDG-PET and CT scans. Brain, heart, kidneys and bladder and tumor volumes were automatically segmented on PET images...

Gene expression is negatively regulated by microRNAs (miRNAs), which commonly act as tumor oncogenes or suppressors. Previous results were inconsistent concerning the relationship between polymorphisms in miRNAs and risk of urological neoplasms. Here, we conducted a comprehensive literature research on diverse databases aiming at enrolling all eligible studies up to August 31, 2016. A total of 13 publications comprising 29 case-control studies were enrolled for three polymorphisms in three miRNAs. Overall analyses suggested significant associations between miR-146a rs2910164 polymorphism and urological neoplasms risk in allelic, homozygote and recessive models...

PURPOSE: Transurethral resection of bladder tumor (TURBT) using a wire loop is considered the gold standard for staging and treating non-muscle invasive bladder cancer (NMIBC). TURBT is associated with serious disadvantages that facilitate tumor recurrence. The present study evaluated the safety and efficacy of the bipolar button electrode for en bloc resection of NMIBC. METHODS: From January 2013 to July 2016, 82 consecutive patients newly diagnosed with NMIBC received transurethral en bloc resection with bipolar button electrode...

Hotspot mutations (c.-124bp G > A and c.-146bp G > A) in the promoter region of the TERT gene have been recently described in several types of solid tumors, including glioma, bladder, thyroid, liver and skin neoplasms. However, knowledge with respect to colorectal precursor lesions and cancer is scarce. In the present study we aimed to determine the frequency of hotspot TERT promoter mutations in 145 Brazilian patients, including 103 subjects with precursor lesions and 42 with colorectal carcinomas, and we associated the presence of such mutations with the patients clinical-pathological features...

INTRODUCTION: Understaging after initial transurethral resection is common in patients with high-risk non muscle infiltrating bladder cancer (NMIBC) and can delay accurate diagnosis and definitive treatment. The rate of upstaging from T1 to T2 disease after repeated transurethral resection ranges from 0 to 28%, although the rate of upstaging may be even higher up to 49% when muscularis propria is absent in the first specimen. A restaging classic transurethral resection of bladder tumour (re-cTURBT) is the better predictor of early stage progression...

High-grade neuroendocrine carcinomas (HGNECs) of the urinary bladder encompass small cell (SCNEC) and large cell neuroendocrine carcinomas (LCNEC). Currently, recommended initial management is with systemic chemotherapy, followed by consolidative therapy with either radical cystectomy or radiotherapy in patients with localized disease. Nevertheless, survival in this setting remains poor. We therefore evaluated the potential to modify arginine metabolism as an alternative, targeted therapy approach in these carcinomas...

Comprehensive consideration is necessary for setting guidelines to evaluate evidence of occupational cancer in painters due to work-related exposure to carcinogens in paint (a phenomenon termed herein as "work-relatedness"). The aim of the present research is to perform a comprehensive review and to suggest criteria for the provision of compensation for occupational neoplasm among painters in Korea. In order to perform a comprehensive review, this study assessed and evaluated scientific reports of carcinogenicities from the International Agency for Research on Cancer (IARC) and the Industrial Injuries Advisory Council (IIAC), as well as reviewed the existing literature about occupational exposure among painters in Korea and the epidemiologic investigations of claimed cases of cancer among painters in Korea...

We studied the expression level of FOXJ1 in bladder epithelial carcinoma and its relation to clinical features and tumor recurrence. From January 2014 to June 2015, 66 patients with bladder epithelial carcinoma were enrolled in this study and their tumor and para-carcinoma tissue samples were collected. FOXJ1 positive expression rate was evaluated using immunohistochemical staining, and FOXJ1 mRNA expression level was measured by RT-PCR. RT-PCR and immunohistochemistry results showed that FOXJ1 expression level in tumor samples was significantly lower than that in para-carcinoma tissue samples...
