Most common ovarian tumor in women under 30? (Both names)

Over 30?

Dermoid cyst (benign cystic teratoma)

Epithelial ovarian tumors

1

Stroma ovarii?

Benign cystic teratoma containing thyroid tissue, which can cause hyperthyroid

2

Most common type of ovarian malignancy?

Epithelial ovarian tumor - Neoplasm arising from the outer layer of the ovary

3

Functional ovarian cyst?

Physiologic cysts of the ovary, which occur in reproductive-aged women

4

Ultrasound features of dermoid cysts?

1. hypoechoic area
2. Hyperechoic band-like strand in hypoechoic medium
3. cystic structure with a fat fluid level

5

Dermoid cyst – typical initial symptom? Most frequent complication? Other complications?

Severe acute abdominal pain; torsion

Rupture, chemical peritonitis

6

Chemical peritonitis? Treatment?

spilling the tumor contents into the peritoneal cavity

Cystectomy or unilateral oophorectomy

7

Immature teratoma? Typical age?

Contain all three germ layers in addition to immature embryonal structures

First and second decade of life

8

Malignant teratomas contain? Tumor grade dependent on?
Tx?

Immature neural elements (quantity determines the dreamed of tumor)

Unilateral Salpingo-oophorectomy

9

Struma ovariaii – on MRI see?

Complex multiloculated mass with thick septa (which are multiple large thyroid follicles)

10

Types of epithelial ovarian tumors?

Serious
Mucinous
Endoetroid
Brenner
Clear cell

11

Types of germ cell tumors?

Dysgerminoma
Endodermal sinus tumor
Embryonal carcinoma
Polyembryoma
Choriocarcinoma
Teratoma

12

Most common type of epithelial ovarian tumor? Location?

Serous; unilateral

13

Mucinous tumors – size? Rupture may lead to? Tx? Associated symptoms? Marker?

Large; pseudomyxoma peritoneii (Mucinous material spills out into intra-abdominal cavity)

Surgical staging, chemotherapy

Malignant ascites, spread to small bowel/momentum, lymphatic extension

CA-125

14

CA-125 postmenopause?

More specific for epithelial ovarian tumors than during reproductive years

15

Adnexal mass – if reproductive age, management based on size?

<5 cm – suggests a functional cyst

Between 5-8 cm – use ultrasound to distinguish

Over 8 cm – likely tumor, should be explored

16

30 y/o Patient with 6 cm adnexal mass – distinguish between functional versus neoplasm how?

Septations, solid components, or excrescences (Growth on surface or inner lining) are consistent with neoplastic process

17

Evaluation of adnexal mass if not reproductive age?

Prepubertal – if mass greater than 2 cm, operate

menopausal – If mass greater then 4-5 cm, operate

18

Granulosa-theca cell tumors versus Sertoli-leydig cell tumors?

Both are solid tumors; produce estrogens versus androgens

19

Find very large tumor on ovary – likely type?

Mucinous tumor
