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...

OBJECTIVE: Pediatric lower urinary tract dysfunction (LUTD) is a common problem in childhood. Lower urinary tract symptoms in children include overactive bladder, voiding postponement, stress incontinence, giggle incontinence, and dysfunctional voiding. Gastrointestinal co-morbidities, including constipation or fecal incontinence, are commonly associated with lower urinary tract (LUT) symptoms in children, often reaching 22-34%. This review summarized the potential mechanisms underlying functional lower urinary and gastrointestinal co-morbidities in children...

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...

OBJECTIVES: We studied the frequency, inter-pathologist variation, appropriateness and utility of immunohistochemistry (IHC) performed on prostate biopsies (PB) to determine the significance of foci of suspicious glands/atypical small acinar proliferations (ASAP). METHODS: We calculated the rate of IHC use and diagnostic rate of ASAP and adenocarcinoma in PB from 01/01/2008 to 06/30/2015 for individual pathologists working in a tertiary academic institution, and correlated them with the pathologists' experience, subspecialization and PB volume with the aim of determining the interpathologist variation and appropriateness of use of IHC according to recently published recommendations, and the usefulness of IHC to resolve foci of ASAP as either benign or adenocarcinoma...

BACKGROUND: A positive surgical margin (PSM) following radical prostatectomy (RP) for prostate cancer is associated with increased risk of biochemical recurrence. We sought to examine whether the pathologist is an independent predictor of PSMs. METHODS: We performed a retrospective review of 3,557 men who underwent RP for localized prostate cancer at our institution from 2003 to 2015. We evaluated 29 separate pathologists. Univariate and multivariable logistic regression were used to test variables previously shown to influence PSM rates...

OBJECTIVE: The inflammatory myofibroblastic tumor (IMT) is a neoplasia with intermediate biological potential, infrequent, with an unpredictable clinical prognosis and a low recurrence rate after an effective treatment. We report two cases of IMT with genitourinary localization, being this entit's publications infrequent. Both presented with little symptomatology, leading to multiple differential diagnosis. The surgical treatment was chosen and pathologic result confirmed the diagnosis...

The concept of genitourinary syndrome of menopause (GSM) was recently introduced and has been gaining widespread use. While some justifications for its introduction are straightforward, others may be questionable. Numerous unspecific symptoms and signs were included in the definition of the syndrome, but the minimum number required for diagnosis was not established. While the GSM definition is designed to facilitate identifying vulvovaginal and urinary estrogen-deprivation-associated symptoms and signs, several concerns have evolved: (1) the syndrome may result in the underdiagnosis of vulvar and urinary pathology; and (2) serious conditions (e...

BACKGROUND Bladder cancer is a major widespread tumor of the genitourinary tract. Around 30% of patients with superficial cancers develop invasive and metastatic pathology. MATERIAL AND METHODS Some new heterocyclic 4-methyl coumarin derivatives were designed using molecular modeling studies to evaluate their potential against bladder cancer lines T24 and RT-4. The designed compounds that showed good binding affinity to T24 and RT4 were synthesized, with excellent yield. The synthesized compounds after structural evaluation were further evaluated for their antiproliferative activity by cell viability assay, cell cycle analysis, and apoptosis assay...

Genitourinary tract is the second most common site where extrapulmonary tuberculosis (TB) occurs. Genitourinary TB is notable for a latent clinical course and difficult diagnosis. The paper presents clinical observations of two patients treated in a urology department of a general public hospital. One of them was diagnosed with tuberculosis of the prostate, MTB+. In the other, TB of the prostate was suspected based on pathologic assessment of the surgical specimen after surgery for prostate cancer.

BACKGROUND Influenza B viruses cause seasonal epidemics of respiratory illness, circulating concurrently with influenza A viruses. However, virological and clinical knowledge of influenza B viruses is less well advanced than for influenza A, and in particular, complications associated with influenza B infection are not as commonly reported. Complications of influenza B infection predominantly include neurological and musculoskeletal pathologies, while a review of the literature shows that bacterial infections associated with influenza B viruses often involve Gram-positive organisms, with a smaller subset featuring Gram-negative species...

Gynecologist and plastic surgeons pioneered the application of lasers in medicine and surgery almost 5 decades ago, initially used to treat cervical and vaginal pathologies. Ever since, energy-based devices have been deployed to treat pelvic pathologies and improve fertility. Recent technological developments triggered an unprecedented wave of publications, assessing the efficacy of fractional laser, and radiofrequency on the vaginal wall in reversing natural aging processes. Studies have shown that a certain degree of thermal energy deposited on the vaginal wall stimulates proliferation of the glycogen-enriched epithelium, neovascularization, and collagen formation in the lamina propria, and improves natural lubrication and control of urination...

Identifying the etiology of acute pelvic pain in girls is often clinically challenging. Particularly in young girls, it is often difficult to determine if acute pelvic symptoms are originating from a gynecologic source or from a genitourinary or gastrointestinal etiology based on the child's clinical examination alone. Therefore, imaging plays a key role in establishing a diagnosis and in directing medical and surgical treatment. Pediatric gynecologic conditions, which can present acutely with pain or mass or both include ovarian torsion, hematometrocolpos, pelvic inflammatory disease, inguinal hernias containing an ovary or the uterus or both, adnexal cysts, pregnancy, vaginal foreign bodies, and ovarian vein thrombosis...

Postoperative spindle cell nodule (PSCN) is a very rare pathologic complication that can occur in association with a recent core needle biopsy, surgery, or trauma. Cases of PSCN have been reported in the lower genitourinary tract, endometrium, and thyroid but are rare in the breast. Herein, we report an ultrasound-guided biopsy-proven PSCN after ultrasound-guided vacuum-assisted excision in the breast.

Urologic pathology is evolving rapidly. Emerging trends include the expanded diagnostic utility of biomarkers and molecular testing, as well as adapting to the plethora of technical advances occurring in genitourinary oncology, surgical practice, and imaging. We illustrate those trends by highlighting our approach to the diagnostic workup of a few selected disease entities that pathologists may encounter, including newly recognized subtypes of renal cell carcinoma, pheochromocytoma, and prostate cancer, some of which harbor a distinctive chromosomal translocation, gene loss, or mutation...
