Two cases of benign polyps of the posterior urethra (ectopic prostatic tissue)

We report two cases of benign polyps of the posterior urethra. Their first symptoms were gross hematuria and urinary frequency. Both specimens obtained by transurethral resection were histologically identified as prostatic tissue. Discussion on benign polyps of the posterior urethra as ectopic prostatic tissue was done with review of literature.     

Hematuria from ectopic prostatic tissue in bulbous urethra

The second case of hematuria from ectopic prostatic tissue residing in the bulbous urethra is presented. A review of this developmental anomaly of the prostate is provided along with a discussion of its embryologic and clinical significance.     

Urethral narrowing due to ectopic prostatic tissue in the bulbar urethra.

Ectopic prostatic tissue in the bulbar urethra is a rare disorder. A case of urethral narrowing due to such tissue is presented. The tissue specimen from the urethral narrowing was positively stained immunohistochemically by the prostatic specific antigen. Urethrocystographic findings are also discussed.     

Ectopic prostatic tissue in urethra

Ectopic prostatic tissue in the urethra is an uncommon lesion. It appears more often in young males. The common presenting symptoms are hematuria or hemospermia It is a benign lesion, and transurethral fulguration is believed to be adequate treatment.     

Ectopic prostatic tissue in the uterine cervix: a report of four cases and review of ectopic prostatic tissue

We report four examples of prostatic tissue occurring in the uterine cervix of patients aged 22, 25, 31, and 77 years. Three were incidental findings in loop excisions (two patients) and cone biopsy (one patient) of the cervix for high-grade squamous dysplasia. One presented as a cervical mass, clinically suspected to represent a fibroid. The prostatic tissue consisted of ducts and acini, some of which had papillary or cribriform patterns. Squamous metaplasia was prominent in all cases. No Wolffian duct tissue was present. The glandular epithelium in all cases was positive for prostatic acid phosphatase and prostate-specific antigen. High molecular weight keratin, performed in two cases, highlighted basal cells in a manner similar to the normal prostate. These unusual cases, only one of which is documented previously, further complicate the often-challenging area of interpretation of benign glandular lesions of the cervix. The unusual phenomenon of ectopic prostate tissue in general is reviewed.     

Papillary adenoma of the prostatic urethra: Report of two cases

Papillary adenoma of the prostatic urethra is a rare cause of hematuria, hemospermia and lower urinary tract obstruction, especially in young adults. We report two cases of papillary adenoma and their endoscopic views. One of the patients had a lesion located on the verumontanum and presented with hematuria, hemospermia and symptoms of lower urinary tract obstruction. The other patient had papillary lesions located in the paramontanal gutter and presented with persistent painless hematuria. The origin of both lesions was proven to be prostatic epithelial differentiation using immunohistochemical identification of prostate-specific antigen. Papillary adenoma is believed to be benign, therefore, both lesions were carefully excised and fulgurated transurethrally.     

Congenital polyp of the prostatic urethra: report on 2 cases

Congenital polyps of the prostatic urethra are an uncommon cause of obstructive uropathy, infection and/or hematuria in male children. A filling defect localized in the posterior urethra on the voiding cystourethrogram represents the peculiar diagnostic finding. Transurethral resection is the treatment of choice, according to the size of the polyp. Two cases of congenital posterior urethral polyps are reported and the main clinical and radiological features are discussed. This lesion has to be considered in the differential diagnosis of the voiding dysfunction in young boys.

Two cases of benign papilloma of the male urethra

Two cases of benign papilloma in the male urethra are reported herein. The first case was a 27-year-old man who complained of miction pain. A pea-sized papillary tumor was found in his external urethral meatus. Urethrocystogram revealed no abnormal findings. He was treated with simple excision and electrofulguration of the tumor and experienced no recurrence of the tumor up to now. The other case was a 24-year-old man who complained of tumor-formation in his distal urethra. Three papillary tumors as large as a grain of rice or a pea were found in his fossa navicularis, besides on panendoscopic examination, a small papillary tumor was found on the bulbous urethra. After he was treated with simple excision and electrofulguration of the tumors on the distal urethra, no tumors were found in his whole urethra on panendoscopy. He also experienced no recurrences of tumor to date. Histologic examinations of both cases revealed squamous papilloma of the urethra. There are a few reports of benign tumors of the male urethra in the Japanese literature. Of them, 48 cases of urethral papilloma in male were collected and are reviewed herein.     

Inverted papilloma of the prostatic urethra: a report of two cases

Two men with inverted papilloma of the prostatic urethra are reported. Case 1 was a 67-year-old man with complaints of gross hematuria and urinary retention. Urethroscopy revealed a smooth-surface tumor with a stalk at the prostatic urethra. Case 2 was a 76-year-old man with complaints of gross hematuria and urinary retention. In these cases, the tumors were resected transurethrally and were consistent with inverted papilloma histopathologically.     

Two cases of perineal ectopic testis

PURPOSE: Perineal ectopic testis is seen very rarely and here we report on two patients with perineal ectopic testis. METHODS/RESULTS: We experienced two cases of perineal ectopic testis on which orchiopexies to the corresponding hemiscrotums were performed. CONCLUSIONS: On surgical exploration, the gubernaculum testes were found to lie fixed to the perineum.

Papillary adenoma of the prostatic urethra

Six patients with papillary adenoma of the prostatic urethra are described. Their ages ranged from 39 to 70 years old. Two of them showed evidence of clinical recurrence 1 year after treatment. The pathological features as well as the immunohistochemical demonstration of prostate specific antigen (PSA) and prostatic acid phosphatase (PAP) are illustrated. A brief review of the literature is discussed with special emphasis on the histogenesis and nature of this lesion.     

Inverted papillomas of the prostatic urethra

Inverted papillomas of the genitourinary tract are uncommon benign neoplasms usually occurring in the urinary bladder and less frequently in the upper urinary tract. To date, there are scant data and no comprehensive studies of inverted papilloma originating in the prostatic urethra. We identified 21 cases and evaluated their demographic, clinical, and histopathologic features. Patients had a mean age of 65.1 years (range: 30 to 89 y), with 10/21 (47.6%) presenting with gross hematuria (n = 8) or irritative symptoms (n = 2) related to the inverted papilloma and 11/21 (52.4%) detected incidentally during work-up/treatment of prostate cancer (n = 6) or benign prostatic hypertrophy (BPH) (n = 5). Fourteen cystoscopically evaluated lesions measured 0.1 to 2.0 cm, and were described as polypoid (n = 9), papillary (n = 4), or an enlarged median lobe (n = 1). Lesions were diagnosed on transurethral resection (n = 8), biopsy/polypectomy targeted to the lesion (n = 6), radical prostatectomy for prostate cancer (n = 4), or biopsy unrelated to the lesion (n = 3). Histologically, 14/21 cases (67%) displayed classic inverted papilloma architecture. The remaining cases showed foci of squamous metaplasia with moderate atypia (n = 4), rare true papillary fronds in a classic inverted papilloma background (n = 2), or both (n = 1). Eleven cases with prostatic tissue revealed adenocarcinoma of the prostate [n = 6; Gleason score 6 (n = 3) or 7 (n = 3)], high-grade prostatic intraepithelial neoplasia (n = 1), benign prostatic hypertrophy (n = 3), or adenosis (n = 1). No patients had a prior history of either inverted papilloma or urothelial carcinoma, whereas 2 patients were diagnosed with high-grade urothelial carcinoma of the bladder synchronous with their inverted papilloma diagnosis. Only 1 of the 18 patients with available follow-up had a recurrence of inverted papilloma in the prostatic urethra. None of the other patients had local recurrences or recurrences at other locations in the urinary tract (mean follow-up 39.9 mo; range: 3 to 120 mo). Inverted papillomas of the prostatic urethra are benign lesions that are commonly detected incidentally and are not associated with a history of urothelial malignancy. Although urothelial carcinoma elsewhere in the genitourinary tract may occur simultaneously, malignant transformation or recurrence as a malignant lesion has not been identified in inverted papilloma of the prostatic urethra.     

Villous adenoma of the prostatic urethra

We present a case of villous adenoma of the prostatic urethra, without malignant transformation. A review of the diagnostic and therapeutic criteria and pathogenic hypotheses on this kind of lesion in the lower urinary tract are made.     

Papillary adenoma of the prostatic urethra

Acquired polyps of the male urethra often present with hematuria and sometimes hemospermia. The histogenesis of these tumors has been debated. We report a case of a prostatic urethral polyp that proved to be of prostatic epithelial differentiation, as demonstrated by immunohistochemical identification of prostatic acid phosphatase and prostatic specific antigen within the tumor cells.     

Inverted papilloma of the prostatic urethra

The inverted papilloma is a rare urothelial tumor, and its localization at the prosthatic urethra is also exceptional. We present a case of inverted papilloma of the prostatic urethra in a 72 years-old male, with symptoms of urinary flow obstruction. The diagnose is obtained after urethrocistoscopy and transurethral resection at the same time. We discuss about the etiology, clinical presentation, diagnose and treatment of this rare tumor, making special attention to its malignancy ability.     

Papillary adenocarcinoma of the prostatic urethra

Three cases of papillary carcinoma of the prostate (also called endometrial adenocarcinoma of the prostate; endometrioid carcinoma) were studied for prostate-specific antigen in order to determine their origin and histogenesis. All 3 cases were prostate-specific antigen positive. Two patients were treated with hormonal therapy, 1 with radiotherapy.
