The Bartholin’s glands and its ducts are located deep in the posterior (back) third of the labia, on either side of the vagina. It secretes thin lubricating mucus, especially at the time of sexual excitation. The glands are small and cannot be felt normally but when the ducts are blocked, a painless cyst may develop. Infection within the cyst may lead to abscess formation which can become extremely painful. Bartholin’s cyst and abscess usually develop in women between the ages of 20 and 30 years.
A cyst is a collection of fluid within a closed sac. Obstruction of the duct leading out of Bartholin’s gland results in accumulation of secretions within the gland. This leads to a painless swelling of the gland, known as Bartholin’s cyst. Infection is an important cause of obstruction. Sometimes, obstruction may be due to congenital (birth defect) narrowing of the duct.
An abscess is a collection of pus in any part of the body, which usually causes swelling and inflammation around it. Infection of a Bartholin’s cyst results in an abscess. This infection may be caused by a number of bacteria, including those causing sexually transmitted diseases (STD) such as chlamydia and gonorrhea, and those residing normally in the intestines such as Escherichia coli (E coli). More than one type of organism may be involved in abscess formation.
A Bartholin’s cyst is usually painless. Swelling of the labia may be felt on one side, close to the vagina. A small cyst often regresses on its own within a few days without any specific treatment.
A Bartholin’s abscess may be extremely painful, making it difficult for the person to walk comfortably or sit down.
A physical examination will usually diagnose a Bartholin’s cyst or abscess. Culture of the drained pus may be done to identify the type of organism involved and to exclude STD. In postmenopausal women, a biopsy may be done to exclude cancer.
