(en'dō-mē'trē-ŭm, -trē-ă), [TA]

The mucous membrane comprising the inner layer of the uterine wall; it consists of a simple columnar epithelium and a lamina propria that contains simple tubular uterine glands. The structure, thickness, and state of the endometrium undergo marked change with the menstrual cycle. The blastocyst implants into the endometrium making the uterus gravid. If implantation does not occur, the superficial part of the endometrium is shed during the (hemorrhagic) menstrual phase of the uterine cycle.

Synonym(s): tunica mucosa uteri [TA]

endometrium

The inner mucous membrane lining of the womb (uterus) that undergoes changes in structure and thickness at different stages of the menstrual cycle, and much of which is shed at menstruation.

endometrium

the lining of the uterus in female mammals, being a glandular MUCUS membrane that undergoes changes during the OESTRUS CYCLE during which it builds up under the influence of OESTROGEN in preparation for receiving the fertilized egg. Where fertilization does not occur, it regresses, or in the case of humans, anthropoid apes and Old-World monkeys, it breaks down over a few days, producing bleeding. See MENSTRUAL CYCLE.

The endometrium was minced with scalpel blades into small pieces (2 to 3 [mm.sup.3]), and aliquots of 500 mg were placed into T25 flasks with serum-free modified DMEM/F-12 containing 10 pg/mL insulin (Sigma, USA), 10 ng/mL transferrin (Sigma, USA), and 10 ng/mL hydrocortisone (Sigma, USA).

Adhesion in the first case was with pores and the hysteroscope appeared to reach the top of the uterine cavity for the first time almost (operated in another hospital), but the hysteroscope was just inserted into the area below the endometrium instead of the uterine cavity by mistake, which leads to a misdiagnosis of severe uterine adhesions.

The presence of cartilage in MMMT is considered a favorable prognostic factor.8 Uterine sarcoma accounts for 3-5% of all corpus uteri malignancies; undifferentiated uterine sarcomas arise from the endometrium or myometrium, lacking any resemblance to normal endometrium and may show heterologous stromal elements in the form of cartilage, bone or rhabdomyoblasts.9 In our case the hyaline cartilage nodules were mostly located deep in the myometrium, close to the serosal surface and adjacent tissue exhibited foci of adenomyosis; the closest differential diagnosis ruminated was adenosarcoma.

EFC is often an incidental finding on ultrasounds, with an incidence of 4% to 14%.1 It has been suggested that a single layer endometrial thickness of 4 mm should be the cutoff value beyond which above endometrial sampling should be performed, regardless of EFC presence, and that the surrounding endometrium and its thickness should be a more important consideration than presence of fluid alone.2,3
