Transurethral bladder tumor resection (TURBT) reportedly increases the circulating tumor cell count in patients with urothelial carcinoma of the bladder (UCB). To determine whether diagnostic TURBT leads to poorer progression-free survival (PFS) than diagnostic cystoscopic biopsy, we retrospectively reviewed the records of 96 consecutive primary pathological high-grade, stage T3/T4 UCB patients treated with radical cystectomy (RC) between January 2009 to December 2013. Clinicopathological features were collected from the medical records...

Clear cell renal cell carcinoma is by far the most common form of kidney cancer; however, a number of histologically similar tumors are now recognized and considered distinct entities. The Cancer Genome Atlas published data set was queried (http://cbioportal.org) for clear cell renal cell carcinoma tumors lacking VHL gene mutation and chromosome 3p loss, for which whole-slide images were reviewed. Of the 418 tumors in the published Cancer Genome Atlas clear cell renal cell carcinoma database, 387 had VHL mutation, copy number loss for chromosome 3p, or both (93%)...

There is a group of lesions in the head and neck region derived from branchial arches and related structures which, when inflamed, are characterized by the formation of cysts lined by squamous or glandular epithelium and surrounded by a heavy inflammatory infiltrate rich in germinal centers. In the thyroid, the main source of various structures which may cause diagnostic dilemma is the ultimobranchial body. To investigate the spectrum of such thyroid lesions, the consultation files were reviewed for thyroid samples containing pathological structures regarded to arise from the ultimobranchial body...

PURPOSE: Recently, a large body of evidence has emerged recognizing that cribriform morphology is an aggressive prostate cancer morphological pattern associated with higher cancer-specific mortality. In a comprehensive analysis, we compared traditional and contemporary prostate biopsy techniques for detection of prostate cancer with cribriform morphology and used radical prostatectomy as a reference standard. MATERIALS AND METHODS: A retrospectively maintained single institution multiparametric MRI (mpMRI) database (n = 1,001) was queried to identify 240 patients who underwent MR/US fusion targeted biopsy (TB) and concurrent systematic biopsy (SB) from December 2014 to December 2016...

BACKGROUND: Choriocarcinoma of the ovary is rare. This tumor can arise from gestational tissue or pure germ cells of the ovary, the former results in gestational choriocarcinoma. The clinical characteristics and histology of both tumor types are identical, differentiation of these tumors is necessary for effective treatment. One strategy for the differentiation of these tumors types is to identify the presence of paternal DNA by DNA polymorphic analysis. CASE PRESENTATION: In the present case, a 27-year-old patient with a history of amenorrhea, lower abdominal pain and vaginal bleeding received a laparoscopic dissection of cystic mass of the right ovary according to an initial diagnosis of ectopic pregnancy...

Vascular anomalies (VAs) are classified as tumors or malformations depending on their clinical characteristics, pathological diagnosis, and genomic information. Diagnosis can be challenging because of the heterogeneity of clinical presentation; thus, the best diagnosis and care are provided by an interdisciplinary team of specialists. Over the past 10 years, an increasing number of pediatric hematologist/oncologists are caring for patients with VAs secondary to new medical therapy options and clinical trials...

Epithelial-to-mesenchymal transition (EMT) is a physiological process that is vital throughout the human lifespan. In addition to contributing to the development of various tissues within the growing embryo, EMT is also responsible for wound healing and tissue regeneration later in adulthood. In this review, we highlight the importance of EMT in the development and normal functioning of the female reproductive organs (the ovaries and the uterus) and describe how dysregulation of EMT can lead to pathological conditions, such as endometriosis, adenomyosis, and carcinogenesis...

REVIEW
James S Wysock, Herbert Lepor
The primary goal of a focal therapy treatment paradigm is to achieve cancer control through targeted tissue destruction while simultaneously limiting deleterious effects on peri-prostatic structures. Focal therapy approaches are employed in several oncologic treatment protocols, and have been shown to provide equivalent cancer control for malignancies such as breast cancer and renal cell carcinoma. Efforts to develop a focal therapy approach for prostate cancer have been challenged by several concepts including the multifocal nature of the disease and limited capability of prostate ultrasound and systematic biopsy to reliably localize the site(s) and aggressiveness of disease...

REVIEW
Shuanzeng Wei, Tahseen Al-Saleem
Sarcomatoid renal cell carcinoma is a highly aggressive tumor. It is not a distinct histologic entity as it can be found in any subtypes of renal cell carcinoma. Recent molecular and genetic evidence suggest that sarcomatoid component is transformed from a common progenitor of the associated renal cell carcinoma, and the TP53 gene plays a pivotal role in this process. The presence of sarcomatoid carcinoma indicates poor prognosis, which also correlates with the amount of the sarcomatoid component. Therefore, the presence and quantity of sarcomatoid component should be reflected in pathology reports...

Background  Intracranial hemangiopericytomas (HPCs) are characterized by high recurrence rates and extracranial metastases. Radiotherapy provides an adjunct to surgery, but the timing of therapy and the patients most likely to benefit remain unclear. Methods  A retrospective review of 20 patients with HPC treated at the University of Texas Southwestern Medical Center between 1985 and 2014 was conducted. Recurrence and metastasis rates along with overall survival (OS) were characterized based on therapeutic approach and tumor pathology using Kaplan-Meier and Cox regression analyses...

Epstein-Barr virus (EBV) is known to be associated with the development of malignant lymphoma and lymphoproliferative disorders (LPDs) in immunocompromised patients. EBV, a B-lymphotropic gamma-herpesvirus, causes infectious mononucleosis and oral hairy leukoplakia, as well as various pathological types of lymphoid malignancy. Furthermore, EBV is associated with epithelial malignancies such as nasopharyngeal carcinoma (NPC), salivary gland tumor, gastric carcinoma and breast carcinoma. In terms of oral disease, there have been several reports of EBV-related oral squamous cell carcinoma (OSCC) worldwide...

The staging of testicular nonseminomatous germ cell tumors (NSGCTs) with lymphovascular invasion (LVI) of the spermatic cord in the absence of cord parenchymal involvement remains controversial. Our previous study showed that tumors with spermatic cord LVI present at a higher clinical stage than tumors with LVI confined to the testis (pT2). We compared NSGCTs with LVI of the spermatic cord without direct involvement of the spermatic cord soft tissues to pT3 tumors to help clarify the appropriate staging of this histologic finding...

Glioblastoma (GBM) is the most common type of malignant tumor found in the brain, and acts very aggressively by quickly and diffusely infiltrating the surrounding brain parenchyma. Despite its aggressive nature, GBM is rarely found to spread extracranially and develop distant metastases. The most common sites of these rare metastases are the lungs, pleura and cervical lymph nodes. There are also a few case reports of skin metastasis. We present the clinical, imaging and pathologic features of a case of a GBM with metastasis to the soft tissue scar and skin near the original craniotomy site...
