Verumontanum mucosal gland hyperplasia is associated with atypical adenomatous hyperplasia of the prostate.
BACKGROUND
Verumontanum mucosal gland hyperplasia (VMGH) and atypical adenomatous hyperplasia (AAH) are both small glandular proliferations that are histologically and topographically unique.


METHODS
One hundred ten randomly selected, whole-mount, radical prostatectomy specimens were reviewed to assess independently the normal histology of the prostatic urethra and periurethral area and the association of AAH with other pathologic features, including VMGH. The degree of nodular hyperplasia was evaluated by total prostate weight for comparison purposes.


RESULTS
Atypical adenomatous hyperplasia was found in 37 cases (33.6%) and was nearly always (32/37) associated with nodules of nodular hyperplasia. Verumontanum mucosal gland hyperplasia was present in 32 cases (29.1%; 21 with AAH, 11 without AAH). There was a significant association between presence of VMGH and AAH (P <.001, Fisher exact test). The degree of nodular hyperplasia was not significantly different between prostates with and without VMGH or AAH.


CONCLUSIONS
These results suggest that AAH and VMGH occur more commonly in prostates when the other is also present.
