Gross pathology of a<unk>  with bleeding Histopathology of a<unk> , H&E stain, low magnification, showing a convoluted layer of mainly granulosa lutein cells, surrounding a fibrous to hemorrhagic center. This type of functional cyst occurs after an egg has been released from a follicle. The follicle then becomes a secretory gland that is known as the<unk><unk> . The ruptured follicle begins producing large quantities of estrogen and progesterone in preparation for conception. If a pregnancy doesn't occur, the<unk><unk>  usually breaks down and disappears. It may, however, fill with fluid or blood, causing the<unk><unk>  to expand into a cyst, and stay in the ovary. Usually, this cyst is on only one side, and does not produce any symptoms. In women of reproductive age cysts with a diameter of less than 5 cm are common, clinically inconsequential, and almost always a physiological condition rather than a cancer or other disease condition. In postmenopausal women the threshold for concern is 1 cm. Although ovarian cancer may be cystic, it does not arise from benign<unk> s. Medical specialty professional organizations recommend no follow-up imaging for cysts which are considered clinically inconsequential. A ruptured<unk><unk>  can cause hemoperitoneum with abdominal pain, and is a common condition in women of reproductive age. It may be confused with ectopic pregnancy.
