Large Gartner cyst.

Gartner cyst is usually an asymptomatic vaginal cyst, measuring less than 2 cm, frequently found during a routine gynaecological examination. Very rarely, as these cysts are closed structures, they may increase in size because of mucus production. We describe here a case of a large Gartner cyst of approximately 8 cm, its differential diagnosis, investigation and vaginal surgical approach (with illustrations), that progressed uneventfully.
