REPRODUCTIVE Flashcards
What is a theca-lutein cyst?
They are cysts due to gonadotropin (hCG) stimulation and may be associated with choriocarcinoma and moles
T/F: both cervical SCC and adenocarcinoma are related to HPV
true
Discuss how estrogen is synthesized in the ovaries
GnRH leads to LH and FSH secretion. LH stimulates desmolase in theca cells to convert cholesterol to androsteinedione; Androstienedione goes from theca cell to granulosa cell where FSH stimulates aromatase to convert androsteinedione to estrogen
Differentiate the lining of a mucinous cystadenoma from that of a serous cystadenoma
Serous = more like fallopian tube; Mucinous = more like intestine (both are ovarian tumors)
What is the most common overall of a “breast lump”?
Fibrocystic change
Which testicular cancer has Reinke crystals?
Leydig cell tumor
What is the way to tell by biopsy that there is endometrial hyperplasia?
The glands are numerous and they are jam-packed together
2 causes of acute prostatitis in young adults; 2 in old adults; WHAT SHOULD YOU PROBABLY PICK???
Young = C. trachomatis and N. gonorrhea; Old = E. coli and P. aeruginosa; In general, probably E. coli
What is the age group for benign and malignant surface epithelial tumors of ovary?
Benign i.e. serous and mucinous adenomas more in young women; Malignant i.e. serous and mucinous cystadenocarcinomas more in older women
Which ovarian tumor increases the risk of endometrial carcinoma?
Granulosa cell tumor because it secretes estrogen

Name 2 pathologies of breast stroma
Fibroadenoma, Phyllodes tumor
What are the expected findings for LH, FSH, Testosterone, and Estrogen in PCOS?
LH increased, FSH decreased, Testosterone increased (because more LH than FSH), Estrogen increased from adipocyte aromatization (increased risk of endometrial CA)
Which forms of estrogen are from 1) ovary 2) placenta 3) adipose (rank strength)
1) 17-beta estradiol 2) estriol 3) estrone (Estradiol > Estrone > Estriol)
This is SCC in situ on the penis presenting as leukoplakia on shaft or scrotum

Nulliparity
What is the general key risk factor for ectopic pregnancy?
SCARRING i.e. endometriosis or PID
What effects can cocaine have on a fetus?
Placental abruption (squeezing of vessels) and intrauterine growht restriction
Discuss the relationship between estrogen and prolactin in pregnancy
Estrogen is high in pregnancy (most from placental estriol), this leads to secretion of prolactin; however, the action at the breast is blocked. So the idea is to get prolactin out but to wait unti after pregnancy is done to really get milk production going!
Anemia in leiomyoma
Fe deficient anemia due to bleeding
What is a hydrocele
failed closure of processus vaginalis
What are the levels of testosterone and LH if there is a testosterone secreting tumor or use of exogenous steroids?
LH decreased; test increased
What is oligomenorrhea and polymenorrhea?
Oligomenorrhea is when there are long cycles (more than 35 d); Polymenorrhea is when there are short cycles (less than 21 d)
Signet ring adenocarcinoma of the ovary
Krukenberg tumor from GI met
T/F: testosterone production is temperature dependent
False; Leydig cells continue to produce testosterone but Sertoli cells are temperature sensitive and decrease sperm production because they will secrete less ABP
What are the levels of testosterone and LH if there is hypogonadotropic hypogonadism?
Both decreased
Which breast cancer has indian filing?
Invasive lobular carcinoma (often bilateral in same location)
What causes a complete mole vs. partial mole?
Complete mole = 2 sperm fertilizing an empty egg; Partial mole = 2 sperm fertilizing 1 egg
What is the histology of ectocervix and endocervix? What if there is endocervix in the vagina?
Ecto = SSNKE; Endo = simple columnar; Vaginal adenosis prob from DES exposure in utero, increases risk of clear cell CA of vagina

Lower = urogenital sinus; Upper = paramesonephric ducts
What effect does progesterone have on gonadotropins?
Inhibits LH and FSH, and decreases estrogen receptor expressivity

Rectal stricture (L1-L3)
Why can choriocarcinoma lead to hyperthyroidism?
Alpha subunit of hCG is same as TSH (and LH and FSH)
Which cells secrete inhibin? Function?
Inhibin is secreted by sertoli cells and inhibits FSH release; this does not affect testosterone synthesis by Leydig cells but will decrease spermatogenesis since FSH stimulates Sertoli cells
What are 2 indications that a ovarian teratoma may be malignant?
If either it is an immature teratoma which may have a neural malignancy OR if it is mature but one of the tissues it formed became cancerous i.e. SCC
Tumor marker for dysgerminoma?
LDH
4 risk factors for endometrial hyperplasia

What should you think for a histology of “fried egg” in 1) Brain 2) Heme 3) Testicle
1) oligodendrocyte 2) neoplastic plasma cell in multiple myeloma 3) seminoma
Germ cell tumors produce things that germ cells would normally make! What is it called when there is 1) Fetal tissue 2) Oocyte 3) Yolk sac 4) Placental tissue? Which MALIGNANCY has the best prognosis and why?
1) Cystic teratoma 2) Dysgerminoma 3) Endodermal sinus tumor 4) choriocarcinoma (Dysgerminoma is the most like oocyte = well differentiated = best prognosis)? Cystic teratoma not malignant usually
What cysts may form in the presence of a choriocarcinoma? Why?
Theca lutein cysts since it is malignant trophoblast it is secreting B-hCG which is normally meant to maintain the corpus luteum, this causes a large corpus leteum = theca lutein cyst
How do you Dx varcocele? Tx?
US; Tx is varicocelectomy or embolization
During which 2 female surgeries is the ureter at risk?
Oopherectomy when ligating the ovarian arteries in the suspensory ligament of the ovary; In hysterectomy when ligating the uterine arteries in the cardinal ligament
What happens to a leiomyoma in pregnancy?
Gets bigger because it is estrogen sensitive
10 common causes of anovulation
Pregnancy, PCOS, Obesity, HPO axis abnormality, premature ovarian failure, hyperprolactinemia (CT of head); thyroid disorder; eating disorder (anorexia shuts down GnRH), Cushing’s, and adrenal insufficiency
What is a serous cystadenocarcinoma?
A malignant non germ cell tumor of ovaries with psammoma bodies
What is the worst and most common breast cancer?

What is retained placental tissue?
exactly what it fucking sounds like; increases risk of hemorrhage and infection
How much of the epithelium is involved in CIN 1; CIN2; CIN 3?
1) less than one third 2) 2 thirds 3) almost full thickness? Full thickness is carcinoma in situ
Name 5 drugs that cause gynecomastia
Ketoconazole, Alcohol, Spironolactone, Digitalis, and Cimetidine (Marijuana and Heroin as well)

What determines the prognosis of a mixed germ cell tumor?
The worst component
What is the most common type of invasive cervical carcinoma?
SCC
What causes endometrial hyperplasia?
Excess (unopposed) estrogen stimulation
Why is metformin often given to PCOS pts?
Because it is associated with insulin resistance
What is the most common pathogen in acute mastitis?
S. aureus (however, supposedly if it spreads far then S. pyogenes because that is basically cellulitis, but if it is more abscess-like, think S. aureus)
What is the deal with ambiguous genitalia in 5 alpha reductase deficiency?
They are ambiguous until puberty because 5 alpha reductase is responsible for their initial development, but testosterone is responsible for the growth spurt of puberty; Thus, they will be essentially normal after puberty
Menorrhagia, dysmenorrhea, dyspareunia with normal sized uterus
Endometriosis
What should you consider if there is menopause before age 40?
Premature ovarian failure
How can cervical cancer cause renal failure?
It can invade laterally into the ureters leading to post-renal azotemia with hydronephrosis and renal failure
Which is associated with an increased risk of SCC: lichen simplex chronicus or lichen sclerosis? Which is post-menopausal?
Lichen sclerosis involves increased risk of SCC (non-HPV vulvar SCC)and is post-menopausal, the epidermal thinning is due to the hormonal changes (i.e. atrophy)
