Abstract
OBJECTIVES
We aimed to better understand the histologic changes in vaginectomy specimens in transgender and gender-diverse (TGD) individuals after prolonged androgen administration.
METHODS
After obtaining institutional review board approval, we reviewed clinical records for all TGD individuals who underwent vaginal tissue resection at our institution between January 2002 and July 2020.
RESULTS
Ten transgender males who underwent vaginectomy for gender affirmation were identified. All patients had been assigned female gender at birth, and the median age at surgery was 41 years (range, 22-74 years). All 10 patients had received androgen for 2 to 10 years preoperatively. The corresponding pathology specimens were examined grossly and microscopically, including with immunohistochemical stains for NKX3.1, prostate-specific antigen (PSA), p501s, and androgen receptor (AR). No gross lesions were identified. Microscopically, prostate-like glands (8/10), urothelial metaplasia (4/10), and vaginal atrophy (8/10) were identified. Seven cases with prostate-like glands showed positive staining with PSA, NKX3.1, p501s, and AR in both squamous and glandular components.
CONCLUSIONS
Recognition of these androgen-related changes enables pathologist to avoid the overdiagnosis of dysplasia. Long-term follow-up is needed to thoroughly understand any potential future implications of these androgen-related changes.
