OB/GYN

Question 1

common pelvic masses

Answer 1

serous epithelial carcinoma
mucinous epithelial carcinoma
choriocarcinoma
sex-cord tumors (granulosa cell tumor, fibroma, thecoma, sertoli-leydig cell tumor)
mature cystic teratoma (dermoid cyst)
serous or mucinous cystadenoma
functional or corpus luteum cyst
theca lutein cysts
endometrioma
leiomyoma
tubo-ovarian abscess
hydrosalpinx
endosalpingiosis

Question 2

serous epithelial carcinoma

Answer 2

symptoms: bloating, early satiety, urinary urgency, and abdominal/pelvic pain
rarely may lead to SBO

Question 3

mucinous epithelial carcinoma

Answer 3

often seen in perimenopausal patients

can become large and lead to SBO or rupture

Question 4

choriocarcinoma

Answer 4

follows a pregnancy
occurs in younger patients
very aggressive

Question 5

sex-cord tumors (granulosa cell tumor, fibroma, thecoma, sertoli-leydig cell tumor)

Answer 5

often composed of cells that produce ovarian hormones, including estrogen and androgens

Question 6

mature cystic teratoma (dermoid cyst)

Answer 6

benign germ cell tumor that may become malignant, however this is rare
most common ovarian neoplasm (benign) in teens and patients in their 20s
can contain elements differentiated to all 3 germ layers

Question 7

serous or mucinous cystadenoma

Answer 7

some of the most common benign ovarian neoplasms

often asymptomatic and found incidentally

Question 8

functional or corpus luteum cyst

Answer 8

occurs when a physiologic occurring follicle/corpus luteum develops but fails to rupture
follicular cysts are smooth, thin-walled, and unilocular on ultrasound
a corpus luteum cyst can look complex and is yellow
typically resolves spontaneously

Question 9

theca lutein cysts

Answer 9

luteinized follicle cysts that form from overstimulation of hCG levels
may occur in a normal pregnancy
gradually resolve weeks to months after the source of hCG is eliminated

Question 10

endometrioma

Answer 10

ectopic growth of endometrial tissue

chocolate cyst/ground glass on ultrasound

Question 11

leiomyoma

Answer 11

benign neoplasm of smooth muscle origin

usually found to be symptomatic in patients in their 30s to 40s

Question 12

tubo-ovarian abscess

Answer 12

found most commonly in women of reproductive age

typically results from an upper genital tract infection

Question 13

hydrosalpinx

Answer 13

a collection of either tubal secretions or pus, often due to a previous infection
seen as a dilated, tubular cystic structure adjacent to the ovary

Question 14

endosalpingiosis

Answer 14

nonneoplastic, ectopic, cystic glands outside the fallopian tube that are lined with fallopian tube-type ciliated epithelium
