Gartner's Duct Cyst (Mesonephric Cyst) in Posterior Vaginal Wall.

In fetus, the reproductive tract consists of two parts, one male (Wolffian duct) and one female (Mullerian duct), and during embryogenesis, because of hormonal influence, the Mullerian duct system develops to form female genital tract, while the Wolffian duct system regresses and may eventually disappear. Gartner's cysts arise from the remnant of mesonephric duct (Wolffian duct) and appear only in approximately 1–2% of the population. They are mostly asymptomatic and small but sometimes can be bigger. Here we report a unique case of a large Gartner's cyst in the posterior vaginal wall with symptoms of dyspareunia and voiding disturbances. After examination, she was diagnosed with vaginal cyst and complete excision was done and confirmed as a mesonephric benign cyst (Gartner's cyst). [ABSTRACT FROM AUTHOR]
