A kidney tumor is a benign or malignant growth of the kidney or renal pelvis .

Benign kidney tumors

Benign (benign) tumors are rare, often symptom-free, and incidental findings from medical imaging .

Possible options include a .:

oncocytic adenoma or oncocytoma (most common benign kidney tumor)
papillary adenoma
metanephritic adenoma
Angiomyolipoma
Fibroma
Hamartoma
multilocular cystic nephroma
Lipoma
Hemangioma

Malignant kidney tumors

Malignant (malignant) tumors are far more common (around 80–85%).

The most important and common forms are:

Renal cell carcinoma , the most common malignant kidney tumor in adults
Wilms tumor , the most common malignant kidney tumor in childhood
Metastases of extrarenal tumors, mostly bronchial carcinoma and colon carcinoma

Details of the classification can be found - unless they can be found in the wiki articles mentioned - in the 2016 WHO classification of tumors of the urinary and male genital tracts.

Clinical manifestations

Kidney tumors can be detected by chance, due to hematuria (blood in the urine), a palpable mass in the abdomen, due to abdominal pain, or due to other symptoms such as paraneoplastic syndrome .
