Chocolate cyst

Endometrial tissue normally lines the inside of the uterus providing a hospitable environment for pregnancy. However, in endometriosis, endometrial-like tissue is abnormally located outside the uterine cavity.
During menstrual periods (when pregnancy has not occurred) part of the endometrium is normally shed resulting in menstrual bleeds, but, in ovarian endometriosis, the endometrial-like tissue cannot be shed resulting in the formation and accumulation of dark brown blood that resembles chocolate in appearance – chocolate cyst.
