Benign renal tumors

Benign renal tumors are rare. They include:

Angiomyolipoma - ultrasound - hyperechogenic deposit /fat tissue/

Angiomyolipoma of the right kindey – CT - hypodense deposit /fat tissue/

• angiomyolipoma,
• hamartoma,
• fibroma,
• hemangioma,
• leiomyoma,
• adenoma - 3 cm in diameter,
• oncocytoma (a type of adenoma that grows from the interstitial cells of the collecting ducts) - it has a round shape and doesn't metastasize. It is often asymptomatic. Histologically we are not able to differentiate an oncocytoma from a chromophobic renal carcinoma, therefore a nephrectomy is recommended.

Biologic behaviour of an adenoma + oncocytoma is unclear - nephrectomy is recommended.
