What is right renal hamartoma? Is it serious?

Hamartoma is clinically called angiomyolipoma, which is a benign lesion of the kidney. It will not cause direct impact on the patient's body. It is different from the renal cancer we usually think of. It includes vascular components, fat components and smooth muscle components. The proportion of fat components is different. Usually the proportion of fat components is more than 75%. Because it contains fat components, it has typical characteristics on B-ultrasound and CT, and can basically be diagnosed through imaging.

In clinical cases, we need to see where the hamartoma grows and its size. Small ones usually have no direct impact on the body and do not need to be treated, but large ones may spontaneously rupture, so close observation is sometimes required. Second, some hamartoma patients have more epithelial components, which are clinically called epithelioid angiomyolipoma. In this case, there is a malignant potential, so this epithelioid angiomyolipoma should be actively treated clinically by surgical removal of the lesion. Moreover, the current nephron-preserving surgery only removes the tumor, and the kidney function will not be significantly affected.
