OVARIAN CYSTS
Definition
 An ovarian cyst is a sac filled with liquid or semi-liquid material arising in an ovary.
Pathophysiology
 Each month, normally functioning ovaries develop small cysts called Graafian follicles.
 At mid cycle, a single dominant follicle up to 2.8 cm in diameter releases a mature oocyte
 The ruptured follicle becomes the corpus luteum, which, at maturity, is a 1.5- to 2-cm
structure with a cystic center.
 In the absence of fertilization of the oocyte, it undergoes progressive fibrosis and shrinkage.
 If fertilization occurs, the corpus luteum initially enlarges and then gradually decreases in
size during pregnancy
 Ovarian cysts arising in the normal process of ovulation are called functional cysts and are
always benign.
 They may be follicular and luteal, sometimes called theca-lutein cysts.
 These cysts can be stimulated by gonadotropins, including follicle-stimulating hormone (FSH)
and human chorionic gonadotropin (hCG).
 Multiple functional cysts can occur as a result of excessive gonadotropin stimulation or
sensitivity.
 In gestational trophoblastic neoplasia (hydatidiform mole and choriocarcinoma) and rarely in
multiple and diabetic pregnancy, hCG causes a condition called hyperreactio luteinalis.
 In patients being treated for infertility, ovulation induction with gonadotropins (FSH and
luteinizing hormone [LH]), and rarely clomiphene citrate, may lead to ovarian
hyperstimulation syndrome, especially if accompanied by hCG administration
 Neoplastic cysts arise by inappropriate overgrowth of cells within the ovary and may be
malignant or benign.
 Malignant neoplasms may arise from all ovarian cell types and tissues.
 By far, the most frequent are those arising from the surface epithelium (mesothelium), and
most of these are partially cystic lesions.
 The benign counterparts of these cancers are serous and mucinous cystadenomas.
 Other malignant ovarian tumors may contain cystic areas, and these include granulosa cell
tumors from sex cord stromal cells and germ cell tumors from primordial germ cells.
 Teratomas are a form of germ cell tumor containing elements from all 3 embryonic germ
layers, i.e. ectoderm, endoderm, and mesoderm
 Endometriomas are cysts filled with blood arising from the ectopic endometrium.

 In polycystic ovary syndrome, the ovary often contains multiple cystic follicles 2-5 mm in
diameter as viewed on sonograms.
Epidemiology
 Ovarian cysts are found on transvaginal sonograms in nearly all premenopausal women and
in up to 14.8% of postmenopausal women.
 Most of these cysts are functional in nature and benign.
 Mature cystic teratomas or dermoids represent more than 10% of all ovarian neoplasms
 Functional ovarian cysts occur at any age (including in utero), but are much more common in
reproductive-aged women.
 They are rare after menop...

I was stuck on this subject and a friend recommended Studypool. I'm so glad I checked it out!
