Ovary PathologyNon Neoplastic Lesions1.) Cystic Follicle - follicular cyst <2cm/<2.5cm
-thin walled with clear fluid contents
2.) Follicular Cyst - most common ovarian mass; non-neoplastic - accum of fluid in follicle; rupture= sterile peritoitis with p
ain - cystic follicle >2cm - lined by granulosa cells which are flattened out be
cause of fluid
3.) Corpus Luteum CYst - most common ovarian mass in pregnancy; corpus luteum that has become cystic; can develop even if not pregnant
- rupture may produce pain or even bleed (corpus lut cyst w/hemorrhage and rupture)
- bright yellow convloluted lining; hemorrhagic center
- lined by luteinized theca cells - >2.5cm
4.) Hyperreaction Luteinalis -
5.) PCOS - cyst with subserosal thickening
6.) Endometiotic Cyst -
Neoplastic TumorsA. Surface Epith - derived from coelomic epith; seed the ementum1.) Serous -
2.) Mucinous -
3.) Endometroid adenoCA -
4.) Clear Cell -
5.) Brenner -
B. Germ Cell Tumors1.) Teratomas - i. Immature - ii. Mature - iii. Monodermal -
2.) Dysgerminoma
3.) Embryonal CA -
4.) Yolk Sac Tumor
C. Sex Cord1.) Granulosa Cell Tumor -
2.) Thecoma - thecoma/fibroma grouphard to differntiate
3.) Fibroma -
4.) Sertoli-Leydig Cell -
Metastatic Tumors1.) Krukenberg Tumor - signet ring cells hematogenous spread usually of a gastric cancers
Clinical Findingssign of seeding from malignant surface - derived cancers; malignant ascites; induration of rectal pouch on digital exam; inc obstruction with colicky painpalpable ovarian mas in postmenopausal women - should not be aplpablemalignant pleural effusion - common site for cancer metscystic teratomas undergo torsion leading to infarct - calcifications from bone and teeth inside these cavitiessigns of hyperestrinism from estrogen secreting tumors - bleeding from endometrial hyper/CA; 100% superficial squamous cells in cervical pap smearhirsutism or virilization from androgen-secreting tumorstumor markers- CA125 and HE4 in surface derived malignant tumors
Clinical and moledcular featrues of 5 most common typesHGSCA, LGCA, MCA, ECA, CCCA = surface derived malignant ovarian tumors
risk factors for high gread serous = BRCA1/2endometrioid = HNPCC - those indiv with early dev't of endometrial and colonic CAsome artists would have developed both cancers=strong family historyprecursor lesions - tubal intraepithelial ca in hHGSCAserous BL tumor in LGSCAendometriosis has role in dev't of ECAcystadenoma? BL tumor? in MCAendometriosis also in CCCA
pattern of spread:hgsca - very early transceloemiclgsca - early transcoelemoic spreadMCA - confined to ovaryendometroid and clear cell - confined to pelvis
CHEMOSENSITIVITYHgsca - highly chemosensitive but poor prognosiscontrasted to favorable prognosis of mucinous and ECA Lgsca and CCCA - low response to chemo but intermediate prognosis
