Kidney adenoma Clear cell

Clear cell kidney adenoma (nephradenoma clarocellulare) is a benign kidney tumor that develops from proximal tubule cells. This rare neoplasm accounts for about 3% of all kidney tumors.

The pathology is a rounded nodular formation of light yellow color, clearly demarcated from the surrounding tissue. The size of the tumor usually does not exceed 5 cm. Microscopically, the adenoma has a tubular or tubulopapillary structure with an abundant vascular network. The tumor cells are light in color with a small amount of cytoplasm.

The disease is asymptomatic and is detected incidentally during examination for another reason. The main diagnostic method is CT or MRI of the abdominal cavity. Treatment consists of organ-preserving operations - enucleation or resection of the kidney. The prognosis after tumor removal is favorable.

**Renal Light Cell Tissue Adenoma** is a rare disease characterized by the presence of a benign tumor (adenoma) in the kidneys. The syndromic name for this pathology is benign nephroadenosis. The term “adenoma” is used only in oncology. This is a tumor-like formation combining mesenchymal and epithelial structures. Blood vessels may also be present in the composition. The peculiarity of this adenoma is that it is completely asymptomatic. Therefore, it can be detected during a routine examination or ultrasound examination. It is noteworthy that the tumor itself usually does not extend beyond the renal capsule. Quite rarely, progressive spread and growth of the tumor beyond the renal borders is observed.
