🔥Subdivision of Epithelial ovarian cancer :
☄ Serrous:
Arises of Epithelial cells :
Single ( fluid-filled cyst)
Either :
✨ benign : Serrous Cystadenoma ( most common - effects premanpusal- 🥂bilateral)
✨Malignant: serrous Cystadenocarcinoma ( inflamed and swallowen lining + postmenopausal women )
❗️Psammoma bodies ( plaques with calcium and cellular debris)
Or Borderline
☄ musinous :
Arises from epithelial cells
( mucus filled cyst) >> large - multioculated
✨ benign: musinous Cystadenoma (🍸unilterall )
✨Malignant: musinous Cystadenocarcinoma ( Like serrous ) = ^
❗️Pseudomyxoma peritioni ( musinous material to the pertonial cavity )
Or Borderline
☄ Endometriod :
Ectopic endometrium-like cells
✨Benign : cyst filled with dark blood
( Chocolate Cyst 🍫)
✨ Malignant: spread to fallopian tube and pertonial cavity
☄ Brenner ( transitional tumor ):-
Transitional epithelial in the surface like those of bladder
☄ Clear-cell ovarian carcinoma :-
rarely appears bilaterally. The cells usually contain glycogen with large clear cytoplasm. It is also associated with endometriosis.

🥀 Surface Epithelial tumors of Ovary :-
🔥The surface of the ovaries is covered with membrane consisting of a lining of simple cuboidal-to-columnar shaped mesothelium. The outermost layer is called the germinal epithelium.
💥It's either benign/ malignant/ borderline
( see the pictures 👇🏻)
NOTE: malignant Tumors characterized by esionphilia

🥀 Sex Cord - stromal ovarian cancer :
🔥It is the tumor that develops from ovarian follicular cells ( sex cord ) or Connective tissue cells ( stromal )
🔥Each ovary contains multiple of follicles ?
💥Follicles is Oocyte surrounded by two types of cells?
1- granulosa cells
2- Thica cells
Which both support follicular development !
🔥 LH stimulates (Granulosa cell ) to secrete ( Androgens )
🔥 FSH stimulates ( Thica cells) to convert Androgens to ( Estradiol) by the enzyme Aromatase
نرجع الان ايش ال Types :
🍂 1- Granulosa thica cell tumor :
( malignant- middle aged women )
>> Estradiol ( estrogen) overproduction :
a) Uterine Bleeding
b) Breast tenderness
c) early puberty in Young
🍂 Fibroma / Thecoma :
😌Fibroma:- benign , asymptomatic
Grossly , ovary fibromas are firm and white or tan. Variants with edema are especially likely to be associated with Meigs' syndrome. Microscopically , there are intersecting bundles of spindle cells producing collagen.
😌Thecoma : benign, estrogen production , in older age women.
Grossly, the tumour is solid and yellow.
Microscopically, the tumour cells have abundant lipid-filled cytoplasm.
🍂 Sertoli-Leydig cell tumors :
Production of Androgens ( male hormones) >> developing male physical characters ( hirsutism , deep voice )

🥀Germ cell ovarian Tumor :
🍂Teratoma :- ( Monster Tumor )
You can find all different type of tissue : hair ,bone, teath ..from all germinal layers ( Dermoid Cyst)
👀 Mature Teratoma:
E.x : Struma Ovarri :
It is defined by the presence of thyroid tissue >> Hyperthyroidism
🍂 Yolk sac Tumor : ( Most common in children) agressive
Germ cell >> Differentiate into Yolk sac tissue
Presence of ring of cells aroung central Blood vessels > called schiller - duval bodies .
Alpha feto protein ^^ high ( increased)
🍂 Choriocarcioma :
Germ cell >>syncytiotrophoblast cells which forms Placenta
Secrete( B-HCG ) which helps ovarian cysts to be formed
🍂 Dysgerminoma:
Germ cell >> Oocyte which is the normal but it turns to grow Uncontrollably
( 😳Most common malignant type of Ovarian Tumors )
🍂 Embryonal carcinoma :- characterized by primitive epithelial cells with marked pleomorphism and various histologic patterns. It may present in pure form but often is part of a mixed germ cell tumor.

te obstruction of artery
Thrombosis >embolism formation > infraction
يمكن يحصل aneurysm > rupture < internal bleeding
وبعدين عرض الدكتور الشرائح

اللي لخصته اليوم بعمل الباثو :
قال الدكتور بأي system ضروري ناخذ الbasic حقه
اي system يحتوي على أربعة أنواع من الأمراض:
1_congenital anomalies(تشوهات )
2_inflammation (immune or infectious )
3_specific disease
4_Tumer
وفي الجراحة نضيف trauma
لماذا يعتبر vascular system اهم system ؟؟
لان 50% من الوفيات سببها complications of atherosclerosis
*basic anatomy :
Aorta>large artery >medium artery >small artery > arteriol > capillary small vein >medium vein >large vein
*histology : Blood vessels consist from three layer :
1_intima (endothelium , subendothelium ) integrity of intima is important for integrity of Blood vessels
2_media (smooth muscle )
3_adventitia (nerve , blood vessel)
اللي يحدد size of artery هو thickness of media حتى تختفي media , adventitia في capillary
*physiology:
Normal function of vascular system is transporting of Blood (nutrient, oxygen and removal of Waste products )
لايغادر blood من vessel ولكن يحصل له filtration
Diseases:
"Congenital anomalies "
1_Arterioveinus (AV malformation ):تتكون كتلة interconnected mixed....
المريض ليس له أعراض ،،،،، يكتشفوا في lung حاجه بيضاء وهي ليست tumer
2_ AV shunt or fistula :direct connection between artery and vein
وهذه قد تكون congenital أو تكون acquired بسبب trauma وقد تكون therapeutic لغرض علاجي مثل hemodialysis
3_ perianeurysm; abnormal dilatation of Blood vessels
وهذا يصيب cycle of Willis ممكن يحصل له accidental rupture >sudden haemorrhage
