Bartholin cyst or abscess
Bartholin glands are found on each side of the vaginal opening. A Bartholin cyst is a buildup of fluid that occurs if the opening of the gland is blocked. A Bartholin abscess may occur if the cyst fluid becomes infected. The Bartholin cyst or abscess appears as a lump or swelling on the side of the vaginal opening.

An ovarian cyst is a sac filled with fluid, or a semisolid material, that develops on or within the ovary. Ovarian cysts are relatively common and usually disappear without treatment.

Nabothian cyst
The cervix is lined with glands that normally secrete mucus. These endocervical glands can become filled with secretions that accumulate as a pimple-like elevation called Nabothian cysts. These cysts are not a threat to health and no treatment is necessary.
