Renomedullary interstitial cell tumor is a benign renal lesion. It is still unclear whether it is a hyperplastic lesion arising in response to hypertension or a benign neoplasm.
They are present in nearly 50% of adults and frequently are multiple. They are common autopsy findings (Lerman et al. 1972).
They affect adults and elderly. Rare in pediatric age.
There is no gender predominance.
Renomedullary interstitial cell tumors are small lesions located in the medulla kidneys.
They are found incidentally in autopsies or nephrectomies performed for other tumors.
Renomedullary interstitial cell tumors are benign lesions.
Although renomedullary interstitial cells play a role in regulation of blood pressure, renomedullary interstitial cell tumors have no correlation with hypertension.
The tumor is usually 1–5 mm in diameter as white or pale gray nodules within a renal medulla (Lerman...
