Endometriosis is defined as the presence of tissue or cells from the lining of the womb (endometrium) elsewhere in the body. It is most commonly found around the uterus and ovaries, but it can be located anywhere in the body except the spleen. In the ovary endometriosis can form cysts containing old blood, also known as chocolate cysts (endometrioma) due to the colour of the contents. When it is in the pelvis it may affect the bowel and the urinary tract (bladder and kidneys). Occasionally it is found in the navel or operation scars. When the tissue from the lining of uterus is found in the muscle layer of the uterus it is called adenomyosis. Sometimes endometriosis and adenomyosis can be found together in the same woman.
