Female Hyperplastic PSA-Positive Prostate Tissue in the Bladder Neck.

We report a rare case of Skene's gland hyperplasia where the serum prostate-specific antigen (PSA) level was measurable. The patient was a 91-year-old woman with a suspected bladder mass at the bladder trigone. Cystoscopy revealed the suspected lesion and an obstructed anterior bladder neck with a large mass located from a "7 o'clock" to "11 o'clock" area. The photodynamic diagnosis was negative. Transurethral subtotal resection of the mass was performed. The serum PSA level at the third postoperative day was 0.08 ng/mL. Postoperative cystography showed no contrast media extravasation. Thus, histopathology revealed massive adenomyomatous hyperplasia of the Skene's gland as well as non-dysplastic urothelium and glandular and squamous epithelium. Immunohistochemistry showed strong PSA and NKX3.1 positivity, confirming the diagnosis of "female prostate". FISH analysis showed only green signals that confirm an XX karyotype. In follow-up to 17 months, there was no disease recurrence or need for a urinary catheter. Effective therapeutic strategies for these lesions are unknown due to the absence of reported cases. Given the patient's age, we assumed that bladder neck resection by transurethral resection with a controlled level of serum PSA would be a suitable therapeutic approach.
