Abstract
Introduction Ectopic prostatic tissue is prostatic tissue located distant from the prostate gland. Although its existence is not uncommon, the occurrence of adenocarcinoma in ectopic prostatic tissue is rare. Case presentation A 68-year-old man was suspected to have a nodular-type tumor in the bladder trigone and a tumor in the prostate based on magnetic resonance imaging and cystoscopy results. Transurethral tumor resection and transrectal prostate needle biopsy revealed the coexistence of ectopic prostatic adenocarcinoma in the bladder trigone and low-risk orthotopic prostate cancer. Four years later, the tumor evolved to intermediate-risk prostate cancer during active surveillance, and the patient underwent prostatectomy with resection of the bladder trigone. Pathology indicated no residual ectopic prostatic tissue or adenocarcinoma at the bladder trigone. Conclusion Adenocarcinoma in ectopic prostatic tissue is very rare; however, when found, the possibility of concurrent cancer in the prostate gland should be considered.

Abstract
The differential diagnosis between high-grade prostate carcinoma and infiltrating urothelial carcinoma (UC) in transurethral resection prostate specimens as well as cystoprostatectomy specimens may often be challenging due to morphologic and clinical overlap of the 2 entities. Such distinction has critical therapeutic and staging consequences, yet it is hampered by both issues in morphology and by the low accuracy rates of single immunohistochemical markers, as reported in literature. This review aims to provide a comprehensive analysis of the available morphological and immunohistochemical parameters, which may allow to discriminate between prostate carcinoma and urothelial carcinoma in the proper clinical context and to discuss their diagnostic applications in daily practice.

Abstract
The most frequent anomaly of the urogenital tract is a simple renal ectopia with one organ lying in the pelvis. Crossed renal ectopia is a less common condition in which the ectopic kidney is located on the opposite side of the midline from the ureteral insertion in the urinary bladder. The cause of both types of renal ectopia is the arrest or failure of the kidney ascent from the pelvic to the lumbar position. Whereas an accelerated ascent leads to a subdiaphragmal or intrathoracic ectopic position, an ectopic ureter can be defined as one that does not drain into the trigonum vesicae. The ectopic orificium can be located situated in the bladder neck and urethra as well as somewhere in the genital area.Exstrophy of the urinary bladder is not a complete ectopia. Because the abdominal wall and the anterior part of the bladder wall are lacking, the bladder mucosa grows directly into the skin. The complex exstrophy of the bladder and intestine corresponds to a cloacal exstrophy, in which the bladder is split in two halves on either side of the gut portion. Testicular ectopia refers to the location of the testis in a position outside of its normal course of descent.Prostatic ectopia does not refer to the wrong location of the entire organ, but to a scattered group of prostate glands, which are mostly found in the submucosal part of the urinary bladder or proximal urethra. Other described locations are the intestinal wall, anus, pericolic fat tissue, spleen, seminal vesicle, testis, and cervix uteri.The associated ectopic penis, scrotum, and penoscrotal transposition are the least common and probably the absolutely most unknown malformations of the male genitalia. The ectopic penis and scrotum are located in the perineum, whereas in the transposition the penis lies above the scrotum.

Abstract
Heterotopic prostate in the dome of the urinary bladder is extremely rare and difficult to diagnose. It is often mistaken for neoplastic masses and histopathological examination is warranted for diagnosis. We report an autopsy case of an ectopic prostate at the dome of the bladder which mimicked a neoplasm on gross pathology.

Abstract
Background Benign ectopia of prostatic glandular tissue in the seminal vesicles is rare with only three prior cases reported in the literature. Prostate cancer, arising within prostatic ectopia in the seminal vesicles, has never been described and therefore presents a challenge in both diagnosis and management. Case presentation Herein, we report a rare case of prostatic adenocarcinoma in ectopic prostate tissue in the left seminal vesicle, without evidence of prostatic glandular involvement. This case was diagnosed on multi-parametric magnetic resonance imaging and confirmed with magnetic resonance imaging-transrectal ultrasound fusion biopsy. Conclusions Awareness of this unusual phenomenon is significant because of the potential occurrence of malignancy to arise in unexpected, extra-glandular locations, which are not routinely sampled on routine transrectal ultrasound biopsy. However attention to lesions with characteristic multi-parametric magnetic resonance imaging features of prostate cancer, regardless of extra-glandular location, will help direct tissue sampling, facilitate a timely diagnosis and ensure appropriate management.

Abstract
Bladder cancer is a common malignancy of the urinary tract, which generally develops in the epithelial lining of the urinary bladder. The specific course of treatment depends on the stage of bladder cancer; however, therapeutic strategies typically involve intravesical drug delivery to reduce toxicity and increase therapeutic effects. Recently, metallic, polymeric, lipid, and protein nanoparticles have been introduced to aid in the treatment of bladder cancer. Nanoparticles are also commonly used as pharmaceutical carriers to improve interactions between drugs and the urothelium. In this review, we classify the characteristics of bladder cancer and discuss the types of nanoparticles used in various treatment modalities. Finally we summarize the potential applications and benefits of various nanoparticles in intravesical therapy.

A case of metastatic cancer with markedly elevated PSA level that was not detected by repeat prostate biopsy. BMC Res Notes 2014; 7:64.

Abstract
Background Prostate-specific antigen (PSA) is a widely used specific tumor marker for prostate cancer. We experienced a case of metastatic prostate cancer that was difficult to detect by repeat prostate biopsy despite a markedly elevated serum PSA level. Case presentation A 64-year-old man was referred to our hospital with lumbar back pain and an elevated serum PSA level of 2036 ng/mL. Computed tomography, bone scintigraphy, and magnetic resonance imaging showed systemic lymph node and osteoblastic bone metastases. Digital rectal examination revealed a small, soft prostate without nodules. Ten-core transrectal prostate biopsy yielded negative results. Androgen deprivation therapy (ADT) was started because of the patient’s severe symptoms. Twelve-core repeat transrectal prostate biopsy performed 2 months later, and transurethral resection biopsy performed 5 months later, both yielded negative results. The patient refused further cancer screening because ADT effectively relieved his symptoms. His PSA level initially decreased to 4.8 ng/mL, but he developed castration-resistant prostate cancer 7 months after starting ADT. He died 21 months after the initial prostate biopsy from disseminated intravascular coagulation. Conclusion CUP remains a considerable challenge in clinical oncology. Biopsies of metastatic lesions and multimodal approaches were helpful in this case.

Abstract
The presence of ectopic prostate tissue in the bladder is common, but the involvement of the bladder dome has rarely been reported. This case report describes a 72-year-old man who presented with gross painless hematuria. Cystoscopy revealed a smooth sessile mass at the dome region of the bladder. A complete transurethral resection of the mass was performed. Histopathological examination of the mass revealed the presence of benign ectopic prostatic tissue.

Abstract
We report an unusual case of retrovesical ectopic prostate tissue in a 73-year-old man with primary prostate cancer. The man’s prostate-specific antigen was 24.66 ng/ml.Transabdominal ultrasonography, pelvic computed tomography,and pelvic magnetic resonance imaging demonstrated a heterogeneous 8.5 × 8.0 × 7.0 cm mass in contact with the posterior wall of the urinary bladder. The patient underwent a retropubic radical prostatectomy and resection of tumor. Pathological examination of prostate revealed a prostatic adenocarcinoma, Gleason score of 4 + 5 = 9, and the retrovesical tumor was confirmed to be a benign prostate tissue.
