Verumontanum-Mukosahyperplasie als Differenzialdiagnose eines Lokalrezidivs nach radikaler Prostatektomie

Abstract

Verumontanum mucosal gland hyperplasia (VMGH) is a benign microacinar proliferative lesion, which occurs exclusively in the verumontanum and the posterior urethra and is one of the lesions that may be confused with a low-risk adenocarcinoma of the prostate gland.We present the case of a 72-year-old male patient who underwent radical prostatectomy due to an adenocarcinoma of the prostate gland (pT2c pN0 cM0 R0, Gleason Score: 3\u200a+\u200a3\u200a=\u200a6). Five years after the operation, we sonographically detected a 3x2\u200acm large tumour in the prostate bed. While our first assumption was a PSA-negative local recurrence following radical prostatectomy, a comprehensive histological examination along with the clinical evaluation led us to the diagnosis of a VMGH. VMGH is a less well-known differential diagnosis of PSA-negative local recurrence following radical prostatectomy, whose clinical manifestation should be presented.
