Endometrial carcinoma of the prostatic utricle

Papillary carcinoma of prostatic ductal origin: a cytologic case report with immunohistochemical and quantitative DNA correlation

This report describes the aspiration biopsy cytology (ABC) of a case of papillary carcinoma of ductal origin, an uncommon malignant tumor of the prostate. Only one case has been previously reported in the cytology literature. Atypical papillary fragments are the distinctive cytologic findings. Similar to well-differentiated acinar carcinoma of the prostate, the cytologic features of malignancy in this lesion may be subtle, and diagnosis is based on the presence of the cytologic pattern. Positive immunohistochemical staining with prostate-specific acid phosphatase confirms the prostatic origin. Application is made of quantitative DNA analysis for prognostic determination.

Utricular papilloma

A benign prostatic utricular papilloma was found in a twenty-seven-year-old man complaining of urethral bleeding and intermittent hematuria after sexual intercourse. Local endoscopic resection was performed. Since the natural history of this lesion is not known, follow-up cystourethroscopy will be performed.

Endometrial carcinoma of prostate

Endometrial carcinoma of the prostate is a unique lesion which contrasts markedly to the more ubiquitous prostatic acinar carcinoma with regard to morphology, clinical manifestations, localization stage at diagnosis, and possibly prognosis. Although endometrial carcinoma of the prostate may occur more commonly than previously recognized, wider recognition and study are essential for further delineation of this lesion. Finally, the inherent limits of endoscopic or of enucleative surgery and the propensity of endometrial carcinoma to present at a low stage suggest in appropriately selected cases that radical prostatectomy or possible external radiotherapy may offer the best opportunity for cure.

Primary transitional cell carcinoma of prostatic periurethral ducts

Primary transitional cell carcinoma of the prostatic periurethral ducts is a distinct histologic variety of prostate carcinoma. Traditional methods of therapy for adenocarcinoma of the prostate are ineffective. A review of the literature suggests that appropriate radical surgical therapy should be considered for early control of this disease.

Endometriosis of the urinary bladder in a man with prostatic carcinoma

A case of endometriosis of the urinary bladder in a man is described. The patient had been treated with estrogen for several years following radical prostatectomy and orchiectomy for prostatic carcinoma. The only other reported case of endometriosis in a male presented in a strikingly similar manner. Pathogenic speculations are briefly presented.

Polyps of the urethra in children

The authors present two cases of polyps of the urethra occurring exclusively in boys: one in a 12-month-old infant, the other in a 15-year-old boy. In both patients the polyp caused dysuria or urinary retention. Diagnosis was based on mictional cystography. This examination usually gives a picture of a filling defect spotted in the area of the bladder neck. During miction the defect may move deeper into the urethra. An endoscopic examination may be also helpful. The authors believe that treatment should consist in total excision of the polyp together with its base through the open urinary bladder. Polyps of the urethra have to be differentiated from a valve of the posterior urethra or a shadowless calculus. After total excision of the polyp prognosis is good.

Oligospermia secondary to müllerian duct cyst. Simple surgical cure

Fertility evaluation of a twenty-three-year-old male with severe oligospermia revealed a müllerian duct cyst that appeared to compress both ejaculatory ducts. Simple endoscopic unroofing of the cyst was followed by disappearance of the mass felt rectally, improvement of the radiographic appearance of the seminal tracts, and a return of the seminal analyses to well within fertile range. Müllerian duct cysts may be a rare cause of surgically correctable male infertility. Endoscopic unroofing of small müllerian duct cysts appears to be the treatment of choice in young males in whom there is concern for preserving fertility and potency.

Papillary adenocarcinoma of prostate

Papillary adenocarcinomas of the prostate are rare tumors which may arise from the prostatic ducts and the utricle; 2 cases are described. The diagnosis of these tumors is best established by cystourethroscopy and transurethral resection. The more common prostatic acinar adenocarcinoma is frequently associated with these tumors. The histopathologic recognition of papillary adenocarcinoma of the prostate and its differentiation from acinar adenocarcinoma is important since the natural history and response to treatment may be different.

Endometrial carcinoma of prostatic utricle with osseous metastases

Endometrial carcinoma of the prostatic utricle is a rare pupillary prostatic tumor arising in the region of the prostatic urethra and verumontanum. Since the first description by Melicow and Pachter in 1967, 8 additional cases have been reported. This case is the tenth reported, and the first in which metastases to bone have been proved by biopsy. Transurethral resection of the tumor with postoperative radiation therapy to the prostatic region and metastases has resulted in clinical improvement. The importance of accurate diagnosis of this neoplasm is emphasized to avoid unnecessary delay in the appropriate choice of therapeutic modalities.

A spectrum of malignant epithelial tumors of the prostate gland

Conceptually, the prostatic territory encompasses neoplams whose origins are intraprostatic, paraprostatic or extraprostatic. Our objectives in this review are to 1) present a classification of the spectrum of malignant epithelial growth encountered in the prostatic territory, 2) show examples of these neoplasms and remark upon their histogenesis, enzyme production and endocrine sensitivity, and 3) suggest re-evaluation of some of our current routine therapeutic procedures.
