Hypernephroma

renal cell carcinoma

 or hypernephroma

Malignant tumour of the cells that cover and line the kidney. It usually affects persons over age 50 who have vascular disorders of the kidneys. It seldom causes pain, unless it is advanced. It may metastasize to other organs (e.g., lungs, liver, brain, bone) and go unrecognized until these secondary tumours cause symptoms. Blood can appear in the urine early on but is painless and usually disregarded. Even when the cancer is in the early stages, X-ray films can show deformity in kidney structures.

Hypernephroma 

a tumor that develops from cells of the adrenal cortex (true hypernephroma) or from the epithelium of the kidney tubules. True hypernephroma is usually benign and manifests itself by distortion of secondary sex characteristics (for example, hirsutism or virilism), hypertension, increased body temperature, and, in children, by premature sexual development. Treatment for hypernephroma is surgical. Hypernephroma of the kidney, known as Grawitz’ tumor or renal cell cancer, is a malignant tumor that arises from the kidney epithelium. It was first described by the German pathologist P. A. Grawitz in 1883. It is found most frequently in males 40-60 years of age. Treatment for it is also surgical.
