Q

Vulvar carcinoma?

A

Can be HPV or non-HPV related. VIN (vulvar intraepithelial neoplasia) is the dysplastic precursor lesion with koilocytic change. Non-HPV related arise due to long-standing lichen sclerosis (>70yo)

Q

Adenosis of the vagina?

A

persistance of columnar epithelium in upper vagina. Increased incidence in females exposed to diethylstilbestrol (DES). Squamous epithelium from the urogenital sinus is supposed to grow up and replace the columnar epithelium lining of the upper 2/3 of the vagina (derived from mullerian ducts)

Q

Role of E6 and E7 in HPV? (super high yield)

A

E6 and E7 are produced by high risk HPV infections. E6 promotes destruction of p53 and E7 promotes destruction of Rb. Loss of tumor suppressor genes increases the risk for CIN.

Q

What is a common cause of death in cervical carcinoma patients?

A

really advanced tumors can invade through anterior uterine wall into the bladder, blocker the ureters resulting in hydronephrosis with postrenal failure.

Q

Presentation of anovulatory cycle?

A

no progesterone phase since no ovulation, just get estrogen driven proliferation of glands until they have to shed. Dysfunctional uterine bleeding

22
Q

Acute endometritis?

A

retained fetal products. fever, abnormal uterine bleeding, pelvic pain

23
Q

Chronic Endometritis?

A

**Plasma cells necessary for diagnosis. **Due to PID, IUD, and TB

24
Q

ENdometrial polyp?

A

Due to side effect of tamoxifen, which has antiestrogenic effects on the breast but weak pro-estrogenic effect on the endometrium

25
Q

Endometriosis?

A

Due to retrograde menstruation. Dysmenorrhea, dyschezia (painful defecation). Chocolate cyst in the ovary. Can cause scaring of the fallopian tubes leading to ectopic pregnancy, gun-powder nodules yellow-brown

26
Q

What is adenomyosis?

A

Endometriosis that spreads to involve the myometrium.

27
Q

Is there an increased risk for carcinoma in endometriosis?

A

Yes, especially in the ovary

28
Q

Buzz word for endometrial hyperplasia?

A

Unopposed estrogen! (obesity, Polycystic ovarian syndrome, estrogen replacement)

29
Q

What is the most common invasive carcinoma of the female genital tract?

A

Endometrial carcinoma

30
Q

What are the 2 types of endometrial carcinoma?

A

Endometriod and serous papillary

31
Q

Characterisitcs of endometriod carcinoma?

A

Hyperplasia precursor, risk factors are unopposed estrogen, nulliparity, obesity. 60 yo @ presentation. Histology looks normal.

32
Q

Characteristics of serous papillary carcinoma?.

A

Sporadic, psammoma bodies, p53 mutation common, 70 yo @ presentation, aggressive behavior

33
Q

What enlarges during pregnancy and shrinks after menopause?

A

Fibroids aka leiomyoma

34
Q

What causes fibroids and what is the histology?

A

related to estrogen exposure. Arise from myometrium. Gross exam shows multiple, well-defined white whorled masses

35
Q

Leiomyosarcoma?

A

malignant prolif of SM from myometrium, de novo, not from leiomyomas, postmenopausal women (70-80yo), single lesion with areas of necrosis and hemorrhage.

36
Q

Q

What tumors will have elevated alpha-fetoprotein?

A

HCC, hepatoblastoma, yolk sac (endodermal sinus) tumor, testicular cancer, mixed germ cell tumor (co-secreted with hCG)

38
Q

What tumors will have elevated B-hCG?

A

Hydatidiform moles and choriocarcinomas (gestational trophoblastic disease), testicular cancer

39
Q

What tumors will have elevated CA-15-3/CA-27-29?

A

Breast cancer

40
Q

What tumors have elevated CA-19-9?

A

pancreatic adenocarcinoma

41
Q

What tumors have CA-125?

What tumors have elevated CEA?

A

Non-specific, but produced by 70% of colorectal and pancreatic cancers, also produced by gastric, breast ,and medullary thyroid carcinoma

44
Q

What tumors have elevates PSA?

A

prostate adeocarcinoma. May also be elevated in BPH and prostatitis

Hairy cell leukemia, B-cell neoplasm

47
Q

What ovarian tumor is associated with BRCA1 mutations?

A

serous carcinoma of the ovary and fallopian tube

48
Q

What is the most common ovarian tumor?

A

cystic teratoma

49
Q

The presence of what two types of tissue indicate that a cystic teratoma may have malignant potential?

A

immautre tissue, usually neural, and somativ malignancy, usually squamous cell carcinoma of the skin

50
