What is the most common solid renal mass in adults?

• A. Wilms Tumor
• B. Transitional Cell Carcinoma
• C. Angiomyolipoma
• D. Renal Cell Carcinoma

Answer: (D)

The most common solid renal mass in adults is Renal Cell Carcinoma. In adults, RCC is the predominant malignant tumor of the kidney and the typical solid lesion arising from the renal parenchyma. Wilms tumor is the leading pediatric renal tumor, not common in adults. Angiomyolipoma is a benign lesion that can appear as a solid renal mass but occurs less frequently and is usually identifiable by its fat content. Transitional cell carcinoma involves the renal pelvis and urothelium and, while it can form masses, it is not the most common solid cortical renal mass in adults. RCC often enhances with contrast on imaging due to its vascular nature, which helps distinguish it from many benign lesions.
