background in surgical pathology, atypical small acinar proliferation is commonly detected in prostate biopsies. most studies on atypical small acinar proliferation have examined morphological characteristics and the utility of immunohistochemical studies.however, these resources are not available to many pathology departments. we have found that examining additional sections is a simple and in...

conclusions although the presence of pni in prostate biopsy is accompanied by higher surgical stages, pni is not an appropriate independent factor in risk stratification. patients and methods this cross-sectional study was conducted using a sample of 109 patients who attended a tertiary health care center from 2008 to 2013. the selection criteria were pni in prostate biopsy with gleason scores ...

conclusions lidocaine-meperidine-diltiazem gel provides significantly better pain control than lidocaine-diltiazem gel and lidocaine gel alone during transrectal ultrasound guided prostate biopsy and probe insertion. this mixture gel is safe, easy to administer and well accepted by patients. results the mean of visual analog pain scale was 4.5 in group a, 3.5 in group b, and 2.0 in group c duri...

This paper discusses the virtual prostate needle biopsy system and the construction of the virtual prostate model, considering the actual distribution of prostate abnormalities. A needle biopsy simulation is performed for the constructed virtual prostate, and the actual biopsy procedure in the clinical situation is evaluated. The prostate needle biopsy is a histologic diagnosis procedure in whi...

Transperineal prostate biopsy is a procedure that can be used to obtain histological samples from the prostate. To improve both the quality of the biopsy core samples and prostate cancer detection, we are currently performing a prospective, randomized trial comparing prostate biopsy samples obtained using an 18 G-needle to those obtained using a 16 G needle. The aim of this preliminary study wa...

BACKGROUND Biopsy Gleason score (GS), in combination with other clinical parameters, is important to take a therapeutic decision for patients with diagnosis of localized prostate cancer. However, preoperative GS is often upgraded after a radical prostatectomy. Increasing the amount of tissue in prostate biopsy may be a way to avoid this issue. We evaluate the influence of a larger biopsy needle...

BACKGROUND The histologic grade of a prostate needle-core biopsy specimen can determine whether a patient with prostate cancer is a candidate for radical prostatectomy or other treatment. Incorrect histologic grading can result in inappropriate treatment and possible liability. Thus, we conducted this study to determine the histologic-grading accuracy of prostate cancer needle-core biopsy speci...

results in the first series, cellularity and blood levels were significantly lower in capillary-fnb compared with cfnb (p < 0.001 and p = 0.011, respectively). there was no significant difference between cfnb and vacfnb in cellularity and blood (p = 0.15 and p = 0.1, respectively). in the second series, cellularity was significantly higher in cfnb compared with vacfnb (p < 0.001) with no signif...

preoperative gleason score (gs) obtained from trans rectal ultra sonography (trus) is the most common grading system to evaluate the appropriate treatment for patients with clinically localized prostate cancer. but this method showed upgraded and downgraded results in comparison to gleason score obtained from radical prostatectomy. the current study aimed to determine clinical or pathological v...

Craniofacial skeletal metastasis is a rare presentation of advanced prostate cancer. This is a report of a 69-year-old man who presented with numbness of the right lower lip and recently ill-fitting lower denture. Based on the medical history of benign prostate hyperplasia (BPH) and suspicion of a metastatic tumor, prostate core needle biopsy was performed. Histology of the prostate biopsy con...
