Endometrium & Myometrium Pathology Flashcards
Endometrium ?
Mucosal lining of the uterine cavity
pathoma-141
Myometrium ?
Smooth muscle underlying the endomatrium
Endometrium is hormone sensitive ?
- Growth = Estrogen = Proliferative phase
- Preparation = Progesterone = Secretory phase
- Shedding = Loss of Progesterone = Menstrual phase
Secondary amenorrhea is called ?
Asherman syndrome
Asherman syndrome cause ?
- Loss of basalis
- Loss of scarring
Loss of ovulation is called —
Anovulatory cycle
141
Result of anovulatory phase ?
Estrogen driven proliferative phase
without progesterone driven secretrory phase (X)
Anovulatory cycle represents —-
Dysfunctional uterine bleeding
Bacterial infection of the endometrium is called ?
Acute endometritis
Presentation of acute endometritis ?
- Fever
- Pelvic pain
- Abnormal uterine bleeding
Acute endometritis cause ?
- Retained products of conception
- After delivery or miscarriage
- Retained products acts as a nidus for infection
Chronic inflammation of the endometirum is called >?
Chronic endometirits
Presentation of chronic endometritis ?
- Abnormal uterine bleeding
- Infertility
- Pain
Characteristics of chronic endometritis ?
- Plasma cell’
- Lymphocytes
Dx of chronic endometrosis ?
Plasma cell
Causes of CE ?
- IUD
- TB
- Retained products of conception
- Chronic pelvic inflammatory disease
- Chlamydia
Hyperplastic protrusion of endometrium —
Endometrial polyp
Cause of which drug is E Polyp ?
Tamoxifen
Presenattion of endometrial polyp ?
Abnormal uterine bleeding
Tamoxifen drug >?
Anti estrogenic effects
Endometrial glands and stroma outside the uterine endometrial lining ?
Endometriosis
Endometriosis presentation ?
- Dysmenorrhea - Pain + Menstruation
- Pelvic pain
- Infertility
Endometriosis causes ?
- Retrograde menstruation
- Implantation at an ectopic site
Most common site of endometriosis?
Ovary
Implants in endometriosis presentation —
Gun powder nodules
Ovary fate in endometriosis?
Chocolate cyst
Endometriosis + Uterine myometrium =
Adenpmyosis
Sites and Effects of endometriosis?
- Uterine ligament = Pelvic pain
- Pouch of douglas= Pain + Defecation
- Bladder = Pain + Urination
- Bowel serosa = Ab Pain + Adhesion
- Fallopian tube mucosa = Ectopic tubal pregnancy + Scarring
PATHOMA-142
Hyperplasia of endometrial flands + Stroma =
Endometrial hyperplasia
Casues of EH ?
- Obesity
- Tamoxifen
- Estrogen replacement
- Polycystic ovary syndrome
Maliganant proliferation of endometrial glands ?
Endometrial cancer
Pathways of endometrial canceer ????
- Hyperplasia pathway- 75%
- Sporadic pathway -25%
Presentation of EH ??
Postmenopausal uterine bleeding
Risk of Ca in EH ?
Single hyperplasia + Atypia
Estrogen dependent pathway ?
Hyperplasia pathway
Risk factor of hyperplasia E Ca ?
- Menarche
- Late menopause
- Nullipority
- Infertility
- Obesity
Sporadic pathway Histo Presentation?
- Serous
- Papillary structure
- Psammoma bodies
- p53 Mutation
Presentation of leiomyoma ?
- Abnormal uterine bleeding
- Pelvic mass
- Infertility
Benign neoplastic proliferation of smooth muc=scle ?
Leiomyoma/Fibroids
Common exposre ?
- Premenopausal women
- Often multiple
- Enlarge during preganancy
- Shrink after meenopasue
Leiomyosarcoma gross -
- Single lesion
- Necrosis
- Hemorrhage
Gross exam of fibroids ?
- Multiple
- Well defined
- White
- Whorled masses
- may dirtort the uterus
- Impinge on pelvic structures
Maliganant proliferate of smooth muscle
Leiomyosarcoma
Leiomyosarcoma histo ?
- Necrosis
- Mitotic activity
- Cellular atypia
Pathoma-144
