What are ovarian cysts? What are the different types of ovarian cysts? The two most common types of cysts are: follicle cysts. In a normal menstrual cycle , an ovary releases an egg each month.

The egg grows inside a tiny sac called a follicle. When the egg matures, the follicle breaks open to release the egg. This causes the follicle to continue growing into a cyst.

Corpus luteum cysts. Once the follicle breaks open and releases the egg, the empty follicle sac shrinks into a mass of cells called corpus luteum. Corpus luteum makes hormones to prepare for the next egg for the next menstrual cycle. Corpus luteum cysts form if the sac doesn't shrink.

Instead, the sac reseals itself after the egg is released, and then fluid builds up inside. Most corpus luteum cysts go away after a few weeks. But, they can grow to almost four inches wide. They also may bleed or twist the ovary and cause pain. Some medicines used to cause ovulation can raise the risk of getting these cysts. Other types of benign ovarian cysts are less common: Endometriomas are caused by endometriosis. Endometriosis happens when the lining of the uterus womb grows outside of the uterus.

A cyst that forms on the eyelid is called a chalazion or meibomian cyst. Some of the cells in the top layer of skin produce keratin, a protein that gives skin its strength and flexibility.

Normally, these cells move up to the surface of the skin as they start to die so they can be shed. But the cells sometimes move deeper into the skin and multiply, forming a sac. They secrete keratin into the middle of the sac, which forms a thick, yellow paste. This can ooze out of the cyst if it's burst. Anyone can develop a skin cyst, but you're more likely to have one if you've been through puberty , you have a history of acne , or you've injured the skin for example, if you've damaged a hair follicle.
