Conditions Of The Uterus, Cervix, Ovary, & Fallopian Tubes Flashcards
Exogenous estrogens administered without progesterone to someone with a uterus may lead to _____ _____ which is a precursor to endometrial cancer
Endometrial hyperplasia
Theca-lutein ovarian cysts are functional cysts that may develop in patients with high serum levels of hCG, such as those undergoing ovulation induction. Characteristically, they regress when?
When gonadotropin levels fall
Luteomas of pregnancy are functional ovarian cysts caused by hyperplastic reactions of the ovarian theca cells secondary to prolonged hCG stimulation during pregnancy. Is surgical resection indicated for this type of cyst?
No — they usually regress spontaneously postpartum
Most common epithelial ovarian tumor
Serous cystadenoma
Most common benign solid ovarian tumor
Fibroma (sex cord stromal ovarian tumor)
The upper vagina, cervix, uterus, and fallopian tubes are formed from the fusion of the _____ ducts by week 9 of gestation, as long as Y chromosome is absent
Paramesonephric (mullerian)
Condition characterized by 2 separate uterine bodies, each with its own cervix, attached fallopian tube, and vagina
Uterus didelphys
Most common neoplasm of the uterus, affecting >70% of women by the fifth decade
Uterine leiomyomas (fibroids)
[most are asymptomatic, but some may present with excess uterine bleeding, pelvic pressure, pelvic pain, and infertility; Most are intramural; most common indication for a hysterectomy]
Medical treatment for benign uterine fibroids
Combination OCPs (usually first-line)
Progesterone-only therapies — Depo, Mirena
GnRH agonists (Depo-Lupron)
Surgical tx of leiomyomas
Myomectomy
Endometrial ablation
Uterine artery embolization
Hysterectomy is definitive therapy
Normal cervical variant in which cyst appears opaque with yellowish or bluish hue, resulting from squamous metaplasia in which layer of superficial squamous cells entrap a layer of columnar cells beneath its surface
Nabothian cervical cyst
Most common benign growths on cervix
Ectocervical and endocervical polyps (endocervical more common)
Usually asymptomatic but can cause coital bleeding or menorrhagia
Conditions associated with endometrial hyperplasia
PCOS and anovulation
Granulosa theca cell tumors (estrogen-producing)
Obesity (secondary to peripheral conversion of androgens to estrogens in adipose cells)
Exogenous estrogens without progesterone
Tamoxifen
[sx include intermenstrual, heavy, or prolonged bleeding that is unexplained]
Dx and tx of endometrial hyperplasia
Dx: sample the endometrium; US reveals endometrial lining >4 mm in a postmenopausal female
Tx: simple and complex hyperplasia WITHOUT atypia is treated with progestin and then resampled in 3 months. Simple and complex hyperplasia WITH atypia is best treated with a hysterectomy
Types of functional ovarian cysts
Follicular cysts
Corpus luteum cysts
Hemorrhagic cysts
Polycystic ovaries
Treatment for serous cystadenomas
Surgical (cystectomy vs. oopherectomy vs. hysterectomy with b/l oopherectomy)
Mucinous cystadenomas are associated with mucoceles of the _____, and rarely can lead to _____ _____
Appendix; pseudomyxoma peritonei
Small, smooth, solid, usually benign ovarian neoplasm with a large fibrotic component that encases epithelioid cells that resemble transitional cells of the bladder
Brenner tumor
Condition characterized by ascites and right pleural effusion (hydrothorax) in association with an ovarian fibroma
Meigs syndrome
Most common ovarian neoplasm found in women of all ages
Benign cystic teratoma (dermoid cyst)
[typically occur in reproductive years]
Diagnosis of benign ovarian tumors
Abdominal and bimanual pelvic exam
US — especially helpful in identifying dermoid cysts
Tumor markers — CA 125 especially in postmenopausal women
Laparoscopy
Management of ovarian epithelial neoplasms
Usually managed with u/l salpingo-oopherectomy
If it is mucinous cystadenoma, perform appendectomy
If young nulliparous pts, may perform cystectomy for ovarian preservation
In older women, a total abdominal hysterectomy with bilateral salpingo-oopherectomy is appropriate
Management of sex cord stromal ovarian neoplasms
Generally tx by u/l salpingo-oopherectomy when future pregnancies are desired
Management of germ cell tumors of the ovary
Can be tx by ovarian cystectomy
Carefully evaluate other ovary since they are b/l in approx. 15-20% of cases
Copiously irrigate pelvis to avoid chemical peritonitis
Types of ovarian torsion
Adnexal torsion — ovary and fallopian tube both twist
Isolated torsion — just the fallopian tube or fallopian tube cysts twist
Primary risk factor for ovarian torsion
Ovarian mass >5 cm
Classic presentation and dx of ovarian torsion
Presents with acute onset of u/l pain; nausea and possibly vomiting
Dx: ultrasound is first line imaging study to identify mass; definitive dx made by direct visualization
Tx for ovarian torsion
Detorsion and ovarian conservation with an ovarian cystectomy
Salpingo-oopherectomy is performed if ovary is necrotic or you suspect a malignancy
