Perineural invasion on biopsy is associated with extraprostatic extension at radical prostatectomy. To our knowledge the significance of perineural in patients who otherwise meet criteria for active surveillance has not been studied.The were Gleason score 6 or less, 2 fewer positive cores and 50% less involvement any core. All cases had least 12 cores. A total 313 met surveillance, elected to undergo immediate prostatectomy institution between 1992 2008. These included 51 262 without...
Sertoli-Leydig cell tumor (SLCT) of ovary is an exceedingly unusual neoplasm that belongs to a group sex cord-stromal tumors and accounts for less than 0.5% all primary ovarian neoplasms. Very few case reports have been documented in the literature so far. Herein, we report poorly differentiated involving left 16-year-old single woman who presented with 3-month history pelviabdominal mass, acne, hirsutism, menstrual irregularities. In addition, review on SLCTs provided.
There are only a few small studies on men with an initial biopsy showing high-grade prostatic intraepithelial neoplasia (HGPIN) who later have cancer repeat and then undergo radical prostatectomy. It is unknown whether this scenario impacts the prognosis of subsequent We compared prostatectomy findings in 45 diagnosis HGPIN subsequently were diagnosed 18,494 lacked earlier HGPIN. All cases retrieved from our institution between 1993 2008. The mean patient age was 60.2 years, serum...
Sanger Sequencing and immunohistochemistry was employed to investigate the TERT promoter mutations protein expression with their association clinicopathological characteristics in over 2200 samples of Middle Eastern origin from 13 different types cancers. The were most frequently present bladder cancer (68.6%), followed by central nervous system tumors (28.7%), thyroid (15.4%), prostate (9.3%), endometrial carcinoma (3.7%), rhabdomyosarcoma (1.4%), colorectal (1%), epithelial ovarian (0.7%)...
Rosai-Dorfman disease (RDD) commonly occurs in lymph nodes, but it can also affect the genitourinary (GU) system. In a search of GU RDD, we identified three cases involving testis and kidney.The mean age was 52.4 (35-76) years. Tumour sizes were 3.6 cm on average (1.5-4.3) for testicular 15.5 renal case treated by nephrectomy. All showed typical morphology similar to nodal RDD with scattered foci lymphocytic aggregation. contrast, all had an evenly distributed lymphocyte plasma cell...
We report a case of 2 year-old girl who presented with three weeks' history deterioration walking, then became unable to walk and later she developed projectile vomiting. Neurological examination revealed bilateral papilledema, nystagmus, truncal ataxia intention tremor. Radiological studies showed an enhancing mass in the posterior fossa extending from cerebellum roof fourth ventricle. The tumor was diagnosed as embryonal abundant neuropil true rosettes (ETANTR). cells neuroblastic...
Lecithin cholesterol acyltransferase (LCAT) is an important enzyme in metabolism that involved the esterification of cholesterol. A lack this results deranged metabolic pathways are not completely understood, resulting abnormal deposition lipids several organs. Clinically, it manifests with proteinuria, dyslipidemia and corneal opacity progressive chronic kidney disease end-stage renal disease.We herein present a case 30-year-old male proteinuria was responsive to empiric management...
A series of 78 cases glomerulonephritis (GN), in which renal biopsy revealed changes GN associated with crescent formation, were reviewed. Renal pathology findings correlated clinical features including patient's age, function, and serologic findings. In most the (71.8%), crescents due to immune complex-mediated GN. This was followed by pauci-immune (20.5%) anti-glomerular basement membrane antibody (GBM) (7.7%). The percentage glomeruli highest anti-GBM disease (mean 93.3%), GBM 48.2%)...
Idiopathic nephrotic syndrome (INS) is a common pediatric disease. Minimal change disease (MCD) the most histopathological subtype and usually has good prognosis. However, in less presentations, INS may have an unusual course that makes renal biopsy necessity to identify its etiology. Immunoglobulin M (IgM) occasionally deposits mesangium can be seen under immunofluorescence (IF). The role of IgM controversial MCD. It likely associated with favorable outcomes for This study aims investigate...
Splenogonadal fusion is a rare benign congenital anomaly with few cases described in the literature. It 16 times more common males than females. A 22 year-old healthy male cryptorchidism presented preoperative imaging strongly suggestive of malignancy. Histopathology after left orchiectomy showed mixed splenic and testicular tissue no sign rarely diagnosed preoperatively. should be included differential diagnoses patients presenting or abdominal mass. Greater recognition this may facilitate...
Abstract Flexible cystoscopy under local anaesthesia is standard for the surveillance of bladder cancer. Frequently, several reusable cystoscopes fail to reprocess. With new grasper incorporated single-use cystoscope retrieval ureteric stents, we explored feasibility using it off-label diagnosis and detection Consecutive diagnostic flexible cystoscopies between Mar 2016 Nov 2018 were reviewed comparing versus disposable cystoscopes. A total 390 patients underwent 1211 cystoscopies. Median...
Background and objectives: To evaluate the frequency of antiphospholipid anti-bodies (APLa) among patients with childhood lupus nephritis (cLN) to assess their impact on long-term renal outcomes. Design setting: This is an observational hospital based study. Patients methods: cLN diagnosed by biopsy seen between January 2002 June 2014 were included. APLa positivity was defined if detection positive 2 occa-sions 6-12 weeks apart during follow up. Demographic features, age at disease onset,...
