Is renal adenoma the same as renal tumor?
Recently, after going to the hospital for a checkup, I found out that I have a renal adenoma. I would like to ask if a renal adenoma is the same as what we commonly refer to as a kidney tumor?
Doctor's answer (1)
Renal adenoma is not a type of kidney tumor.
Kidney tumors refer to any type of tumor occurring in the kidney, including both benign and malignant tumors. Renal adenoma specifically refers to a benign tumor arising from the adrenal cortex or renal glandular tissue. Renal adenomas usually grow slowly and are often asymptomatic, commonly discovered incidentally during physical examinations or other abdominal investigations.
Renal adenomas mainly originate from the adrenal glands. They are benign tumors primarily composed of eosinophilic or basophilic cells, with uniform nuclear size and orderly cell arrangement. In contrast, kidney tumors mainly originate from kidney tissue and can be either benign or malignant. They have a complex range of pathological types, including renal parenchymal cell tumors, renal transitional cell tumors, and several other types.
If a renal adenoma is detected, doctors will decide whether surgical removal or other treatment measures are necessary, based on its size, growth rate, and the patient's overall health condition.
