18. Benign and Malignant Conditions of the Uterus, Cervix and Ovaries Flashcards
Upper vagina, cervix, uterus, fallopina tubes formed by mullerian/paramesonephric ducts, asbence of Y chr and absence of mullerian inhibiting substand leads to devel of mullerian and degen of wolfian.. failure of paramesonephric ducts to fuse can lead to what which is 2 spearate uterine bodies with its own cervix, attached fallopian tube and vagina?
Uterus didelphysis
Incomplete dissolution of midline fusion of para duct leads to septate uterus, Mullerian agenesis (meyer rokitansky kuster hauser syndrome) is the complete lack of development of para system, causing absence of uterus and most of the vagina… the MC congenital cervical anomalies are didelphys cervix and?
septate cervix
*uterine/cervical are spontaneous or due to DES where you see Tshaped endometrial cavity
What is a b9 tumor of smooth muscle cells of myometrium, MC neoplasm of uterus, 70% women have them by 50s, asymptomatic, symptomatic: AUB, pelvic pressure, pelvic pain, infertility, MC indication for hysterectomy, risk: inc age during reproductive years, AA women 2-3 fold, nulliparity and family hx?
Uterine Leiomyomas “Fibroids”
Leiomyomas “Fibroids” path is unknown, 40% enlarge during preg, they are spherical, well circumscribed, white firm lesions w WHORLED appearance, may degenerate or cause pain, or bleed, may calcify in postmeno pts, located subserosally beneath uterine serosal surface, submucosally beneath endometrium , or located where, which is MC?
Intramural fibroids within the myometrium
Leiomyomas “Fibroids” - 80% are asymptomatic, sx have lower back or pelvic pain, fullness, freq urination, prolonged/heavy bleeding incresed incidence of infertility, bimanual examination can reveal enlarged irregular uterus, - if mass moves = fibroid, what is often performed and can help distinguish between adnexal mass and lateral leiomyomas?
ULTRASOUND
Leiomyomas “Fibroids” are treated via combination of estrogen and progesterone OCP- first line, progesterone only therapies such as depoprovera or mirena IU system, gonadotropin releasing hormones (GnRH agonist) such as depo lupron which can decrease fibroid size up to 40% in 3 months instead of surgery. Surgical tx via myomectomy, endometrial ablation, uterine artery embolization (microsphers polyvinyl alcohol particles are introduce into uterine artery and occlude feeding vessel)—- definitive therapy is?
Hysterectomy
Myomectomy tx for Leiomyomas “Fibroids” - if endometrial cavity is entered future delivers must be c section, fibroids will grow back. What polyps create small friable protustion into endometrial cavity, causing menorrhagia, spontaneous or post meno bleeding, US shows focal thinkening of endometrial STRIPE*, most are BENIGN hyperplastic masses?
Endometrial Polyps
*visualization via hysteroscopy
What cyst is a normal vairant, appear opaque with yellowish or bluishe hue, vary in size 3mm to 3cm, result from squamous metaplasia in which a layer of squamous epi cells entrap layer of columnar cells beneath its surface- columnar cells continue to secrete mucus and a mucus retnetion cyst is formed?
Nabothian cervical cyst
What polyp is MC b9 growth of cervix, sx are none, coital bleeding or menorrhagia, removed in office, rarely malignant, endocervical polyps are MC and beefy red in color and arise from endocervical canal?
Cervical polyps
*ectocervical polyps less common and pale
What represents overabundance growth of endometrial lining as a result of persistent unopposed estrogen such as PCOS/anovoluation, granulosa theca cell tumor, obesity, exogenous estrogen and tamoxifen, is a precursor to endometrial cancer (2-3%)?
Endometrial hyperplasia
Endometrial hyperplasia has 3 types: simple hyperplasia without atypia (1% progress to cancer) complex hyperplasia without atypia (3%) Simple hyperplasia with atypia (9%) complex hyperplasia with atypia (27%)
MEOW
Endometrial hyperplasia symptoms include intermenstrual heavy or prolonged bleeding, dx via bx of endometrium, US reveals endometrial lining is >4mm in postmeno woman, tx simple/complex without atypia with progestin and rebx in 3 months, treat simple/complex with atypia with?
HYSTERECTOMY
What ovarian cysts are lined by one or more layers of granulosa cells, develops when ovarian follicle fails to rupture, clinically signifcant if large enough to cause pain?
Follicular Cyst
What ovarian cyst is bilateral and can become large, may develop in pts with high serum levels of hCG, pregnancy, choriocarcinoma or hydatidiform molar pregnancy, who are undergoing ovulation induction, characteristically regress when gonadotropin levels fall- functional cyst?
Theca-Lutein Cyst
Luteom of pregnancy is cuased by hyperplastic reaction of the ovarian theca cells, secondary to prolonged hCG stimulation during pregnanacy, appears as reddish brown nodules, usually regress spontaneously postpartum. What is associated with chronic anovulation, hyperandrogenism, and insulin resistance with multiple small follicles that are inactive and arresting in antral stage, increased LH levels promote androgen secertion from ovarian theca cells leading to elevation levels of androstenedione and testosterone, peripheral converions of androgen to estrogen results in elevated estrogen levels that then suppress FSH from the pituitary gland?
POLYCYSTIC OVARIAN SYNDROME
