CIN 1 involves
Less than 1/3 of the thickness of the epithelium
CIN 2 involves
less than 2/3 of the thickness of the epithelium
CIN 3 involves
Slightly less than the entire thickness of epithelium
Unlikely to reverse
Late complications of Cerivical carcinoma
Invade through the anterior uterine wall into the bladder blocking the ureter
High grade dysplasia in cervical carcinoma is characterized by cells with
Hyperchromatic (dark) nuclei and high nuclear to cytoplasmic ratios
Growth of the endometrium is driven by
Estrogen
(Proliferative phase)
Preparation of the endometrium for implantation is driven by
Progesteron
(secretory phase)
Asherman syndrome is a loss of
Basalis
Endometrial Polyps arise as a side effect of
Tamoxifen
Endometriosis is
Endometrail glands and stroma ouside of the uterine endometrial lining
Location of endometeriosis
Ovary: chocolate cyst
Uterine ligament: pelvic pain
Pouch of Douglas: pain with defecation
Adenomyosis is
Endometeriosis that involves uterine myometrium
Psammoma bodies found in
Thyroid papillary
Meningioma
Papillary serous carcinoma (endometrium)
Mesothelioma
LH:FSH in PCOD
greater than 2 because you have a great increase in LH and decrease in FSH

CA-125
Surface epithelial ovarian tumors derived from
Coelomic epithelium
What mutation increases risk of serous carcinoma of ovary and fallopian tube
BRCA1
Endometriod surface epithelial ovary tumors arise from
Endometriosis

Reinke Crystals seen in
Sertoli-Leydig cell tumor
Meigs syndrome is
Fibroma, Pleural effusion, and Ascites
Pseudomyxoma peritonei is
Massive amounts of mucus in the peritoneum
Pseudomyxoma peritonei is due to
a mucinous tumor of appendix
Placenta previa (implantation of placenta in lower uterine segment) presents as
Third trimester bleeding
Placenta accreta is
