Urinothorax is an uncommon thoracic complication of genitourinary (GU) tract disease, which is most frequently caused by obstructive uropathy, but may also occur as a result of iatrogenic or traumatic GU injury. It is underrecognized because of a perceived notion as to the rarity of the diagnosis and the absence of established diagnostic criteria. Urinothorax is typically described as a paucicellular, transudative pleural effusion with a pleural fluid/serum creatinine ratio >1.0. It is the only transudate associated with pleural fluid acidosis (pH < 7...

BACKGROUND: The accumulation of somatic genetic alterations drives carcinogenesis. Little is known, however, about how the level of genetic alteration across an entire cancer genome affects tumor grade, stage or survival. OBJECTIVE: To investigate the influence of somatic mutation count (MC) and copy number variation (CNV) on pathologic and oncologic outcomes in patients with genitourinary malignancies in The Cancer Genome Atlas (TCGA). DESIGN, SETTING, AND PARTICIPANTS: TCGA data sets for adrenocortical carcinoma (ACC), bladder urothelial carcinoma (BLCA), chromophobe renal cell carcinoma (RCC; KICH), clear cell RCC (KIRC), papillary RCC (KIRP), pheochromocytoma and paraganglioma (PCPG), prostate adenocarcinoma (PRAD), and testis germ cell tumor (TGCT) were accessed via cBioportal...

Leiomyoma, the benign tumor of smooth muscle cell origin, is commonly seen in genitourinary and gastrointestinal tracts. Primary intracranial leiomyoma, however, is extremely rare occurrence. We hereby report a case of Epstein-Barr negative primary intracranial leiomyoma in a middle-aged renal transplant recipient, which mimicked left frontal parasagittal meningioma on neuroimaging. The tumor was completely excised and diagnosis of leiomyoma was clinched on pathological analysis with immunohistochemistry. The patient improved after tumor removal, and no evidence of tumor recurrence was noted on follow-up study after 10 months postsurgically...

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: To investigate mechanisms underlying our previous observation of a large rise in serum prostate-specific antigen, a marker of prostate pathology, during both sexually transmitted and systemic infections, we measured serum high-sensitivity C-reactive protein (hsCRP), a marker of systemic inflammation, in our previous case-control study of young, male US military members and compared our findings to those for PSA. METHODS: We measured hsCRP before and during infection for 299 chlamydia, 112 gonorrhea, and 59 non-chlamydial, non-gonococcal urethritis (NCNGU) cases; before and after infection for 55 infectious mononucleosis (IM) and 90 other systemic/non-genitourinary cases; and for 220-256 controls...

Parkinson's disease is a systemic disorder with widespread and early α-synuclein pathology in the autonomic and enteric nervous systems, which is present throughout the gastrointestinal canal prior to diagnosis. Gastrointestinal and genitourinary autonomic symptoms often predate clinical diagnosis by several years. It has been hypothesized that progressive α-synuclein aggregation is initiated in hyperbranched, non-myelinated neuron terminals, and may subsequently spread via retrograde axonal transport. This would explain why autonomic nerves are so prone to formation of α-synuclein pathology...

CONTEXT: - Pathologic diagnosis of tumors in the genitourinary system can be challenging based on morphology alone, particularly when diagnostic material is limited, such as in core biopsies. Immunohistochemical stain can be a useful tool to aid in the diagnosis. OBJECTIVE: - To provide an update on practical applications and interpretation of immunohistochemical stains in the diagnosis of tumors in prostate, kidney, bladder, and testis. We particularly focus on difficult differential diagnoses, providing our insights in frequently encountered challenging situations...

Objectives: Pathologist workload in the United States has traditionally been measured by relative value units (RVUs), which is often criticized for providing an inaccurate estimate of actual work. This study compares three methods for measuring workload. Methods: Surgical pathology and cytopathology workload for 1 representative month at Stanford Health Care was assessed using three different methods: RVUs, Royal College of Pathologists (RCP) point system, and University of Washington-Seattle (UW) slide count method...

BACKGROUND: Retrospective identification of Gleason pattern 4 in metastatic Gleason score 3 + 3 = 6 (GS6) radical prostatectomy (RP) specimens has suggested true GS6 prostate cancer (CaP) lacks metastatic potential. However, pathologist awareness of study design and metastasis outcomes at the time of RP review might have introduced upgrading bias. We used pathologist-blinded methodology for unbiased characterization of metastasis rates for contemporarily defined pathologic GS6 (pGS6) CaP...

Epidemiological and biological evidence indicates a causal relationship between the presence of proliferative atrophic lesions and the development of prostatic intraepithelial neoplasia (PIN) and prostate cancer. The presence of inflammatory and atrophic lesions of the prostate is widely underestimated and they are not generally mentioned in pathology reports. We performed a histopathological concordance study among eight genitourinary specialists and seven generalist pathologists, using 116 histological slides of prostate lesions, including proliferative atrophic lesions, PIN, and cancer...
