Abstract
Verumontanum mucosal gland hyperplasia (VMGH) is a relatively common benign proliferative lesion which was first described by Gagucas et al in 1995. VMGH is usually found in radical prostatectomy or transurethral resection specimens and rarely in needle biopsy specimens. The histologic feature of VMGH is characterized by well-circumscribed proliferation of small glands and thus VMGH may mimic low grade adenocarcinoma. We report a case of VMGH from a 61-year-old man. The lesion coexisted with prostatic adenocarcinoma on radical prostatectomy specimen. The lesion was a well circumscribed microacinar proliferation which was present between the openings of ejaculatory ducts. The acini consisted of two cell layers with inner secretory cuboidal epithelium and outer basal cell. Typically, the lumen contained many corpora amylacea. Nuclear pleomorphism, prominent nucleolus, or mitotic figure was not identified. Because of small gland proliferation of VMGH, this lesion can be confused with other small gland proliferative lesions, such as low grade adenocarcinoma, atypical adenomatous hyperplasia, basal cell hyperplasia, mesonephric hyperplasia, and nephrogenic adenoma. To avoid misdiagnosis of VMGH as carcinoma, one should be familiar with this lesion.
