It is defined as the presence of endometrial tissue outside the uterus. The clinical manifestations of endometriosis are protean. The presence of endometrial tissue in the myometrium is termed adenomyosis. Superficial implants of endometrial tissue may occur throughout the peritoneal cavity, along serosal surfaces and in the abdominal wall. Deep infiltrating endometriosis occurs when implants infiltrate the peritoneum and serosa by at least 5 mm and involve visceral organs. Histologically, these lesions are characterized by fibromuscular hyperplasia around foci of endometriosis which sometimes contain small cavities (Koninckx et al. 1994). The majority of patients have superficial endometriosis, usually asymptomatic, with the commonest site of involvement being the ovaries, uterine ligaments, pouch of Douglas, serosal uterine surface, fallopian tubes, rectosigmoid junction, and bladder dome. Deep infiltrative endometriosis is symptomatic and causes significant morbidity including chronic pelvic pain, infertility, haematuria, and rectal pain and bleeding.\nAccess this chapter\nTax calculation will be finalised at checkout\nPurchases are for personal use only\nSimilar content being viewed by others\nReferences\nBazot M, Darai E, Hourani R, Thomassin I, Cortez A, Uzan S, Buy J.
