abscess cyst
If the fluid within the cyst becomes infected, you may develop a collection of pus surrounded by inflamed tissue (abscess). A Bartholin's cyst or abscess is common. Treatment of a Bartholin's cyst depends on the size of the cyst, how painful the cyst is and whether the cyst is infected. Sometimes home treatment is all you need. In other cases, surgical drainage of the Bartholin's cyst is necessary.
