How to diagnose hamartoma renal cancer

Renal hamartoma, also known as renal mesenchymal tumor or renal mixed tumor, is a relatively rare benign tumor that can appear in bones, brain, heart, lungs and other parts of the body. It is composed of abnormally proliferating blood vessels, smooth muscle and adipose tissue. Renal hamartoma can be unilateral or bilateral, with varying sizes. Clinical manifestations include butterfly-shaped sebaceous adenomas on the face, or reduced skin pigmentation on the trunk, which is leaf-shaped, and sharkgrass-like changes on the back skin. The brain is poorly developed, and in severe cases, there may be epileptic seizures. Other organs such as eyes, bones, heart, and lungs may also be accompanied by lesions. What are the differential diagnosis methods for renal hamartoma? Let's discuss it below.

Differential diagnosis of renal hamartoma

The diagnosis of renal hamartoma is not difficult. What are the differential diagnosis methods for renal hamartoma? Patients can undergo X-ray examination, intravenous pyelography, ultrasound examination, CT examination, renal artery angiography, etc.

1. X-ray examination: There are transparent areas in the tumor, calcification in the renal area, unclear renal contours, and the psoas major muscle shadow disappears.

2. Intravenous pyelography: The mass compresses the renal pelvis and calyces, and the deformation of the renal pelvis and calyces is difficult to distinguish from renal cancer.

3. Ultrasound examination: Hamartoma contains a large amount of fat and vascular smooth muscle, which can produce strong echo reflections, while renal cancer does not contain fat tissue and has a lower echo.

4. CT examination: It can show a mass with uneven density. It is the main diagnostic method for renal hamartoma. The negative value is different from renal cancer.

5. Renal artery angiography: It plays an important role in the diagnosis of renal hamartoma. It can be seen that the blood vessels of hamartoma are either grape-shaped or cystic, while the blood vessels of renal cancer are rich and disordered, accompanied by arteriovenous shunts.

How is renal hamartoma treated?

Patients with tumors smaller than 4 cm do not need to take medication or surgical treatment, but only need close follow-up. After follow-up, if the tumor has not decreased in size and arterial embolism and bleeding occur, effective measures should be taken to protect some renal function. Patients with tumors larger than 5 cm should undergo nephron-preserving surgery. Patients with huge tumors and invaded lymph nodes should undergo nephrectomy. Patients with huge tumors that have impaired renal function should also undergo nephrectomy. Patients with tumor rupture and bleeding should undergo bilateral nephrectomy. Patients with renal failure should undergo kidney transplantation or hemodialysis.

I believe everyone already knows what are the differential diagnosis methods for renal hamartoma and how to treat it. If you still have related questions, consult a doctor or a doctor in a specialized hospital. The doctor will tell the patient the answer according to the patient's specific situation. I wish the patient a speedy recovery and a happy and fulfilling life.
