Reproductive Pathology Flashcards
Klinefelter Syndrome
47 XXY. Testicular atrophy, eunuchoidal appearance, tall, slender gynecomastia. Presence of barr body in nucleus (electron dense area in nucleus). Common cause of hypogonadism and infertility.
Causes dysgenesis of seminiferous tubules. Decreased inhibin and increased FSH. Also abnormal leydig cell function. Decreased testosterone, increased LH, increased estrogen.
Turner Syndrome
45 XO. Short stature, webbed neck, shield chest. Streak ovary.
Preductal coarctation (Xoarctation of aorta). Horseshoe kidney.
Most common cause of primary amenorrhea. No barr body.
Decreased estrogen leads to increased FSH and LH. Can result for mitotic or meiotic error.
XYY males
Phenotypically normal. Increased antisocial behavior, normal fertility. Autism spectrum sometimes
True hermaphroditism
46 XX or 47 XXY. Ovotesticular disorder. Ovotestes present. Ambiguous genitalia. very rare.
Female pseudohermaphrodite
Ovaries present but ambiguous external genitalia. Due to excessive exposure to angrogenic steroids. Like CAH (21OH deficiency)
Male pseudohermaphrodite
XY testes present but external genitalia are ambiguous or female. Can be due to 5areductase deficiency or androgen insensitivity syndrome.
Male pseudohermaphrodite
XY testes present but external genitalia are ambiguous or female. Can be due to 5areductase deficiency or androgen insensitivity syndrome.
Kallman Syndrome
Failure of GnRH cells to migrate. Anosmia with decreased GnRH decreased LH and FSH. Low fertility.
Complete mole
46 XX or 46 XY, super high HCG, can convert to choriocarcinoma, no fetal parts, happens when sperm reached enucleated egg. Causes vaginal bleeding, increased uterine size, preeclampsia, hyperthyroidism.
Shows snowstorm appearance or bunches of grapes.
Partial mole
69 XXX 69 XXY 69 XYY, slightly increased HCG, has fetal parts, no choriocarcinoma. Causes vaginal bleeding, has fetal parts on imaging.
Gestational hypertension
Greater than 140/90 after 20th week. No proteinuria or end organ damage. Deliver at 39 weeks.
Preeclampsia
Fibrinoid necrosis of spiral arteries in placenta, hypertension >140/90 after 20th week. Causes edema and stuff. Severe features can include headache, thrombocytopenia.
Severe form is HELLP syndrome (hypertension, elevated liver enzymes, low platelets).
Give IV magnesium sulfate to prevent seizures deliver at 34 or 37 weeks
Eclampsia
Preeclampsia and maternal seizures. Maternal death from stroke sometimes.
HELLP syndrome
Hypertension, elevated liver enzymes, low platelets. Can cause thrombocytopenia, microthrombi in liver causing schistocytes.
How to treat hellp?
A-methyldopa, hydralazine
Placental abruption
Causes painful bleeding, often from cocaine. Causes premature separation of placenta from uterine wall. Usually occurs in third trimester.
Placenta accreta
Placenta touches wall of myometrium
Placenta increta
Placenta penetrates into myometrium
Placenta percreta
Placenta penetrates through myometrium. Can attach to rectum or bladder.
Risk factors for placenta accreta, increta, percreta? Presentation?
Prior c section, placenta previa. Presents with no separation of placenta after birth. Massive bleeding. Life threatening.
Placenta previa
Attachment of placenta to lower uterine segment. Lies near or covers the os. Risk factors include multiparity or prior c section.
Placenta previa
Attachment of placenta to lower uterine segment. Lies near or covers the os. Risk factors include multiparity or prior c section.
Ectopic pregnancy
Usually in ampulla. Risk increases with PID, ruptured appendix. Often mistaken for appendicitis. Often has lower HCG than expected.
Polyhydramnios
Associated duodenal/esophageal atresia, anencephaly. maternal diabetes. Treat with indomethacin to reduce fetal urine.
Endometritis
Inflammation of the endometrium associated with retained products of conception following delivery. Treat with gentamicin and clindamycin
Endometriosis
Non-neoplastic endometrial glands/stroma outside of the endometrium. Most commonly in ovary, pelvis, peritoneum.
Characterized by cyclic pelvis pain.
Adenomyosis
Where the endometrium dives down into the myometrial layer. Treat with hysterectomy
Endometrial hyperplasia
Abnormal gland proliferation usually caused by excess estrogen. Risk for endometrial carcinoma. Usually presents as postmenopausal menstrual bleeding.
Risk factors include PCOS, granulosa cell tumor, anything that increases estrogen
Endometrial carcinoma
Most common gynecologic malignancy usually at 55-65. can present with vaginal bleeding and is typically preceeded by endometrial hyperlasia.
Risk factors usually due to increased estrogen without progestins
Endometrial carcinoma
Most common gynecologic malignancy usually at 55-65. can present with vaginal bleeding and is typically preceeded by endometrial hyperlasia.
Risk factors usually due to increased estrogen without progestins
Leiomyoma
uterine fibroid. A benign smooth muscle tumor with rare malignant transformation. Estrogen sensitive. Can cause abnormal uterine bleeding
