The search for the precursor of invasive prostatic adenocarcinoma has intensified in recent years, focusing on the spectrum of histopathologic changes referred to as high-grade prostatic intraepithelial neoplasia. This microscopic finding, considered to be the most likely precursor of invasive carcinoma (7), is characterized by cellular proliferations within pre-existing ducts and glands, with ...

Transrectal prostatic ultrasonography has been performed in 203 patients within the last year. This new diagnostic modality has proven reliable in quantitating decrease in volume of the primary tumor following therapy in 71% of patients with prostatic carcinoma (10 of 14 patients) in whom long-term follow-up is available. In 12 patients staged prior to radical prostatectomy, prostatic ultrasono...

We report a case of symptomatic intraurethral prostatic cyst in a 42-yr-old man without clinical evidence of benign prostatic hyperplasia. The intraurethral cyst makes it unique from the all previously reported cases of prostatic cysts located medially within the prostate. Transurethral resection of the cyst with limited resection of the prostatic tissue at the base of the cyst was performed wi...

We report a case of benign polyp with prostatic-type epithelium of the urinary bladder. A 58-year-old male presented with gross hematuria. Cystoscopic examination revealed a 2-mm polypoid lesion in the mid trigone. Immunohistochemical demonstration of prostatic acid phosphatase and prostatic specific antigen in the urothelial cells as well as the prostatic-type epithelial cells suggested the hi...

left psoas major lesion was neurofibroma, which excluded metastatic STUMP. After one year of follow-up, there was no sign of metastasis or recurrence. Prostatic STUMP, arising from specialized hormone-dependent mesenchymal cells of the prostate, is a quite rare neoplasm. To our knowledge, prostatic STUMP presenting as a huge bladder mass has not been reported yet. Prostatic STUMP is manifested ...

OBJECTIVE Urothelial prostatic involvement (UPI) at the time of radical cystoprostatectomy (RCP) was found associated with worse survival outcomes by several previous reports. Our aim is to evaluate the impact of different levels of UPI on survival outcomes using a large series of male patients treated with RCP. METHODS Whole step section specimens from 995 male BCa patients were assessed for...

Canine prostatic disease is commonly evaluated with abdominal ultrasound and radiographs. Mineralization of the prostate is often reported, but the clinical relevance of this finding is currently not known. The-purpose of this study was to characterize the relationship between ultrasonographic and radiographic prostate mineralization and the final diagnosis. Medical records of 55 dogs with evid...

OBJECTIVE To investigate the prognostic significance of prostatic involvement by bladder urothelial carcinoma using the new 2009 TNM staging system. METHODS From 1993 to 2008, 77 consecutive men who were clinically and/or pathologically diagnosed with bladder cancer underwent radical cystectomy. Patients were classified into several groups, according to the presence, extent and invading pathw...

OBJECTIVE Primary prostatic tuberculosis is a very rare form of presentation of the tuberculous infection, which is generally caused by the M. tuberculosis, and which has shown an increase in incidence and prevalence, due to an increase of immunocompromised patients and the pandemic of the Syndrome of Acquired Immune Deficiency (AIDS).We describe a case of primary prostatic tuberculosis attende...
