Prostatic tissue ectopia within the seminal vesicle: a potential source of confusion with seminal vesicle involvement by prostatic adenocarcinoma

Ectopic prostatic tissue: histogenesis and histopathological characteristics

“…Ectopic prostatic tissue is a relatively uncommon or underreported entity that is most commonly encoun-tered in the lower male genitourinary tract, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] and occasionally in the female genitourinary tract. [17][18][19][20][21][22][23] Other sites outside these regions have been described, including the anal canal, 24 pericolic fat, 25 retroperitoneum, 26 and spleen.…”

An unusual case of retrovesical ectopic prostate tissue accompanied by primary prostate cancer

“…Ectopic prostate is an unusual but not uncommon finding in the genitourinary tract [5]. Most aberrant prostatic tissue occurs in the urethra [6] and urinary bladder [7], but has also been observed in the testis [8], epididymis [9], seminal vesicle [5], cervix, and vagina [10].…”

“…Most aberrant prostatic tissue occurs in the urethra [6] and urinary bladder [7], but has also been observed in the testis [8], epididymis [9], seminal vesicle [5], cervix, and vagina [10]. Up to now, a few cases of retrovesical ectopic prostate have been reported in English medical literature [2-4].…”

Ectopic prostatic tissue in the perineum

“…Ectopic prostatic tissue has been described widely throughout the body, most commonly in the urethra, seminal vesicles, epididymis, testis and urinary bladder. [5][6][7][8][9][10] Clinically, they present with lower urinary tract symptoms; haematuria being most common but obstructive symptoms such as urinary frequency and retention also feature. Outside of the genitourinary system, ectopic prostatic tissue is a distinctly uncommon phenomenon but has been reported in the spleen, rectum and uterine cervix, as well as in ovarian teratomas.…”
