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.
