Regurgitant/implantation from retrograde menstrual flow of endometrial cells
Transformation of coelomic epithelial cells
Vascular or lymphatic dissemination of endometrial cells
Microscopy of endometriosis
Red-blue to brown nodules - powder burn
Chocolate cysts in ovaries - endometriomas
Relation of fibroids to oestrogen
Oestrogen stimulation important
Regress in menopause
Enlarge during pregnancy
Microscope of fibroids
Bundles of smooth muscle cellar
Complication of fibroids during pregnancy
Red degeneration
Here haemorrhagic infarction occurs
Severe abdominal pain
Post partum torsion can also occur

Pathophysiology of endometroid endometrial cancer
Oestrogen excess
Usually in peri-menopausal women

Pathophysiology of non endometroid endometrial cancer
Unrelated to oestrogen excess
Usually in elderly women with endometrial hypertrophy
