Renal Cell Carcinoma (RCC)
![Page 3: RCC](https://reader033.fdocuments.us/reader033/viewer/2022051617/55a515f91a28abed7f8b45e0/html5/thumbnails/3.jpg)
Renal Cell Carcinoma
Incidence:
• 85% of renal tumors.
• ♂:♀ = 2:1
• Age: 50-70 Yrs.
![Page 4: RCC](https://reader033.fdocuments.us/reader033/viewer/2022051617/55a515f91a28abed7f8b45e0/html5/thumbnails/4.jpg)
Renal Cell Carcinoma
Pathology:
• Tubular epithelium.
![Page 5: RCC](https://reader033.fdocuments.us/reader033/viewer/2022051617/55a515f91a28abed7f8b45e0/html5/thumbnails/5.jpg)
Renal Cell Carcinoma
Pathology:
• Vary from being nearly completely cystic to being completely solid.

Renal Cell Carcinoma
Pathology:
Bilateral RCCs:1. Von Hippel-Lindau syndrome2. Tuberous sclerosis.3. Chronic dialysis.4. 2% of sporadic cases.
Multicentric RCC:- 25% of patients.
![Page 7: RCC](https://reader033.fdocuments.us/reader033/viewer/2022051617/55a515f91a28abed7f8b45e0/html5/thumbnails/7.jpg)
Renal Cell Carcinoma
Pathology:
Spread:1. Direct local invasion of adjacent structures.
2. Local regional lymph node metastases.
3. Extend into the renal vein and, subsequently, into the inferior vena cava.
4. The lungs are the most common sites of distant metastases.
NB: Typically, skeletal metastases are purely lytic.

Renal Cell Carcinoma
Clinical:
• Hematuria, flank pain, or less frequently a flank mass.
• Incidentally during imaging.
• Occasionally, patients present with systemic symptoms such as fever, nausea, anorexia, and weight loss.
• Rarely, patients have symptoms related to humoral factors such as parathormone, prolactin, erythropoietin, or renin.

Renal Cell Carcinoma
Plain X-Ray:
• Normal.
• Distort the normal renal contour.
