The two most common Benin tumer are

A

Papillary adenoma. >Asymptomatic
Oncocytoma.> symptomatic and arising from distal tubule (collecting duct)
🪭Onco means pink so it has pink cytoplasm (eosinophilic cytoplasm)

Q

is the most common type of kidney cancer, and it typically represents around 80-85% of all kidney malignancies. RCC originates from the cells lining the small tubes in the kidney that filter waste from the blood.

في دي الحاله لازم يخرجو كل الbladder برا يعملو cystectomy وفي الغالب ياخذو الileum ويعملو modification يجربوه ل bladderبس لها مضاعفات لكن احيانا يضطرو يسووها

Q

🌟🌟🌟Familial From of RCC(this is very imp syndrome

A

(VHL syndrom)von hippel_lindau syndrom
⚡️فيه VHLجين موجود على كروموسوم ٣ (لما يصير له mutation المريض رح يكون عنده الsyndrom
-it is an autosomal dominant means that if he inherit one abnormal gene from one of his patient they will develop the syndrome
-it has higher association RCC
➡️ VHL is subtype of RCC
🔽
Associated with clear cell type
سميت كذا لان الخلايا حقت السايتوبلازم نظيفه يعني بيضاء بسبب انو الfatتحلل من مادهزالفورمالين الضافه
-it is state syndrom charactrais by by: Hemangioblastomas (is a brain tumor)
غالبا يكون بايلاترال وملتبل ليجن-
يعني إذا عند المريض RCC by this syndromفي كليه وحده الكليه الثانيه معرضه للخطر انو بجيها RCC

A

🥁All RCCl large and spherical masses
🥁Cut surface yellow-gray-white or tan-brown.
🥁معضم الRCCتكون cystic وفيها hemorage
🥁usualy have well defined margin
🎸most characteristic feature of RCC is Invasion of the renal vein
الRCCيحب الvein ينمو فيه(في الصور لى نلاحظ عندنا massجنب الvein ثم الmassهذا يروح يمشي للvein وينمو جواته او ممكن يروح ينمو في ال adrenal glandاللي فوق الكلى

Q

Extra renal effect Of RCC

A

🍨Fever>الخلايا في الار سي سي تفرز سايتوكاينز هذي الساينوكاينز تؤثر على مركز معين في الجسم اسمه هيبوكامبس فيرفع والمريض يجي له فيڤر
🩸معضم الtumors تسبب fevor لهذا السبب⤴️
Polycythemia 5-10% (erythropoetin
release)
🍭الRCCهي cells secrete erithropoiten like substance ف المريض يجب له polycythemia
يعني الRbcsزادت عند المريض
🍧الRCC من الtuners اللي تحب تغزو
It like to invaid the vein
ف الrisk of hematognus spread is high so it has commonly metastasis للكلى و الboneواحيانا الskin كمان يكون عندو mad في الskinتشبه الRCC
