What Are Chocolate Cysts?

Chocolate cyst or ovarian endometrioma is a type of cyst found in the ovaries. These fluid-filled cysts are noncancerous and sometimes found within or encapsulating the ovaries. This condition gets its name due to the fluid present inside the cyst which is brown in color with a tar-like appearance, closely resembling the melted chocolate. Studies have shown that around 30-40 % of women are affected by ovarian endometrioma.

Endometriosis is a condition in which the uterine lining grows outside the uterus. A severe form of endometriosis can lead to the chocolate cyst.
Women with endometriosis have higher chances of retrograde menstruation or menstrual backflow. Due to endometriosis, patches of endometrial cells that grow in the ovaries, form cysts. The retrograde menstruation can lead to trapping of blood in these cysts and produce inflammation in the surrounding tissues.
