• Slit-like openings of ejaculatory ducts.
• Orifice of prostatic ducts.

In 5 procedures, it was not possible to advance the endoscope directly into the urethra, and thus, the cystoscope was advanced through the proximal urethra over a guide wire until the verumontanum was visualized (Figure 1).

Verumontanum mucosal gland hyperplasiain prostatic needle biopsy specimens: a mimic of low grade prostatic adenocarcinoma.
These cysts are typically located in the midline, posterior to the bladder, originating in the region of the verumontanum. Mullerian duct cysts do not communicate with the prostatic urethra, but are connected to the verumontanum by a thin stalk.
Cystoscopy revealed 2 tumours measuring 1.8 x 1.6 cm and 1 x 1.2 cm on the anterior wall of the bladder, and one metastatic tumour measuring 0.8 x 1 cm on the prostatic urethra near the right side of the verumontanum. Histological examination of the biopsy specimens revealed grade 1 non-invasive bladder transitional cell carcinoma and urethral transitional cell carcinoma.
Verumontanum mucosal gland hyperplasia was present in 32 prostates (29%) (Table 1).
At the bulbar urethra, in place of the verumontanum, there was a lumen of about 24 Fr into the redundant vagina.
Prostatic duct adenocarcinoma (PDA), originally believed to represent endometrial carcinoma derived from the prostatic utricle,[5] may present as a papillary mass in the prostatic urethra and typically is associated with hematuria and/or obstructive symptoms, thus clinically mimicking BPEPs.[6-8] Like BPEPs, these tumors are often papillary and exophytic and are initially found in the prostatic urethra near the verumontanum.[6,7] The exophytic characteristic has been attributed in 1 case to the post-transurethral resection and evagination of prostatic epithelium.[9] At least 1 reported case of PDA was thought to arise in preexisting BPEPs.[10]
The routine surgical procedure started with an incision on both sides of the verumontanum at the apex area.[sup.4] Bilateral longitudinal incisions from the bladder neck to the verumontanum were made at the 5 and 7 o'clock positions.
Each procedure began by making an incision at the proximal part of verumontanum from the 5 to the 7 o'clock positions.
This report focus on 5 peculiar cases in boys: a 4-year-old with a fibrovascular polypoid of the verumontanum, a papilloma in a newborn, a hemangioma of the prostate in a 4-year-old, and 2 teenagers with papillary urothelial neoplasms of low malignant potential (PUNLMP).
