Vaginal Squamous Cell Carcinoma:

• HPV 16 association.

Cervix disorders:

Acute and chronic cervicitis:

Acute:

• Inflammation due to infection by: C. trachomatis, N. gonorrhoeae, T. vaginalis, Candida, and HSV.

• Follicular cervitis: caused by C. trachomatis.

Chronic:

• Persistent acute cervicitis.

Pap smear:

• Screen out squamous dysplasia and cancer.

• Adequate estrogen = superficial squamous cells (SSC).

• Adequate progesterone = intermediate squamous cells (ISC).

• Lack of estrogen and progesterone = parabasal cells PC.

• Nonpregnant woman = 70% SSC + 30% ISC.

• Pregnant woman = 100% ISC.

• Elderly woman = PC.

• Findings: Malodorous discharge; postcoital bleeding.

• Distant metastasis.

• CIN I: mild.

• CIN II: moderate.

• CIN III: severe.

Oral contraceptive pills:

• Estrogen + progesterone.

• Progesterone: inhibit LH.

• Hostility to sperm.

Changes during pregnancy:

• Increased plasma volume and RBC mass.

• Respiratory alkalosis.

• Increased serum thyroxine and cortisol.

Menopause:

• Increased FSH, LH; decreased estrogen and progesterone.

• Secondary amenorrhea, hot flushes, night sweats.

Increased testosterone (ovaries) or increased DHEA-sulfate (adrenal origin) cause:

• Hirsutism or virilization.

Polycystic ovarian syndrome (POS):

• Increased LH and androgens and estrogen; decreased FSH.

• Findings: menstrual irregularities, hirsutism, infertility, obesity.

• Hypothyroidism.

Amenorrhea:

• Absence of menses.

Causes:

• Hypothalamic or pituitary disorder: decreased FSH/LH.

• Ovarian disorder: decreased estrogen and progesterone.

• End-organ defects.

Uterine disorders:

Acute:

• Due to bacterial infection; S. agalactiae.

Endometritis: chronic:

• Retained placenta, gonorrhea, intrauterine device.

Adenomyosis:

• Stratum basalis invaginates into myometrium.

• Findings: menorrhagia, dysmenorrhea, pelvic pain.

Endometriosis:

• Glands and stroma located outside uterus.

Locations:

• Most common is ovaries.

Findings:

• Dysmenorrhea, painful menses, intestinal obstruction, ectopic pregnancy, enlarged ovaries.

Treatment:

• Laparoscopy.

Endometrial hyperplasia:

• Too much estrogen.

• Causes: nulliparity, obesity, POS.

• Findings: menorrhagia; increased risk of endometrial carcinoma.

Endometrial carcinoma:

• Very common.

• OCPs decrease risk.

• Risk of breast cancer.

• Types: well-differentiated adenocarcinoma, papillary adenocarcinoma.

• Findings: post-menopausal bleeding.

Leiomyoma (fibroids):

• Benign smooth muscle tumor.

• Findings: menorrhagia, obstructive delivery.

Fallopian Tube Disorders:

Pelvic Inflammatory Disease:

• Causes: N. gonorrhoeae or C. trachomatis.

• Gives rise to hydrosalpinx.

• Complication: oophoritis.

Ectopic Pregnancy:

Causes:

• Most common cause is scarring from previous PID; endometriosis, altered tubal motility, SIN.

Findings:

• Pain, bleeding, adnexal mass, hypovolemic shock.

Complications:

• Rupture, hematosalpinx.

Diagnosis:

• Beta-hCG, ultrasound, laparoscopy.

Ovarian disorders:

Tumors:

• Risk: nulliparity, mutant BRCA1 and BRCA2; Lynch syndrome; Turner's syndrome; Puetz-Jeghers syndrome, smoking; OCPs decrease risk.

Types of tumors:

• Surface-derived (most common), germ cell, sex cord-stromal tumors, metastasis.

• Findings: ascites, increased abdominal girth, induration in rectal pouch on DRE, intestinal obstruction with colicky pain; ovarian mass, pleural effusion, infarctions, hyperestrinism.

• Markers: CA 125.

Placental Abnormalities:

Placenta previa:

• Implantation over cervical os; bleeding, painless.

Abruptio placentae:

• Premature placental separation; due to smoking, cocaine, hypertension, advanced age.

Preeclampsia/eclampsia:

• Toxemia of pregnancy.

• Abnormal placentation.

• Decreased natural vasodilators.

• Increased vasoconstrictors.

• Premature aging of placenta.

• Infarctions, atherosclerosis of spiral arteries.

Findings:

• Hypertension, proteinuria, edema, seizures, renal and liver disease, HELLP syndrome.

Hydatidiform moles:

• Benign tumor of chorionic villus.

• Neoplastic placenta.

• 46XX.

• Findings: preeclampsia, large uterus, increased hCG; snowstorm appearance on ultrasound.

Choriocarcinoma:

• Malignant tumor made of syncytiotrophoblast and cytotrophoblast.

• Spreads to: lungs, vagina; lesions are hemorrhagic.

Treatment:

Chemotherapy.

Down syndrome triad:

• Decreased urine estriol, decreased AFP, increased beta-hCG.

Nipple discharges:

Bloody:

• Intraductal papilloma, ductal cancer.

Purulent:

• Acute mastitis due to S. aureus.

Greenish-brown discharge:

• Mammary duct ectasia.

Breast pain:

• Causes fibrocystic change.

• Mondor's disease: superficial thrombophlebitis of breast veins; painful and palpable.

Fibrocystic change:

• Blue domed cysts.

• No malignancy.

• Sclerosing adenosis.

• Ductal hyperplasia.

Benign breast tumors:

Fibroadenoma:

• Most common in women younger than 35 years old.

• Movable mass.

• Enlarges during pregnancy.

Phyllodes tumor:

• From stromal cells.

• Leaf-like extensions.

Intraductal papilloma:

• Blood discharge.

• Women younger than 50.

Breast cancer:

• Mean age: 64 years old.

• Family history, genetics.

• AD disease.

• BRCA1 and BRCA2.

• Li-Fraumeni syndrome: inactivated TP53 suppressor.

• RAS, ERBB2, RB suppressor.

• Due to: prolonged estrogen exposure; smoking, radiation, endometrial cancer.

• Painless mass.

• Skin, nipple retraction.

• Mammography: screening; cannot differentiate benign from malignant.

• Spreading: first by lymphatics, then hematogenously.

• Spreads to: lungs, bone, liver, brain, ovaries.

• Treatment: radical mastectomy; damage to long thoracic nerve causes winged-scapula; lumpectomy; radiation.

Breast cancer in men:

• BRCA2 mutated; Klinefelter's syndrome.

• Poor prognosis.
