UNLABELLED Synchronous occurrence of benign and malignant kidney tumours is very rare. We present the case of a 63-year-old female patient who underwent a bilateral partial nephrectomy after being diagnosed with bilateral kidney tumours by ultrasonography and a computed tomography scan. Histopathological analysis of the left kidney tumour mass revealed a chromophobe renal cell carcinoma. In the...

was first established by Robin in 1855. Later, yellow coloured tumours of small or large size, well circumscribed, vascular, liable to haemorrhages, degeneration and cyst formation were noticed in the region of the kidney, which led pathologists to speculate concerning their origin. At first they were thought to be lipomatous in structure until Grawitz in 1883 thought that the structure was ide...

The commonest urogenital tumours in childhood are Wilms tumour of the kidney and rhabdomyosarcoma in the pelvis. We review these tumours along with other primary renal tumours and less common ovarian and testicular tumours in childhood. Current clinical concepts, relevant staging investigations and imaging features are described.

Background: Glomus tumour is a rare mesenchymal neoplasm affecting the subcutaneous tissue of the distal extremities in the majority of cases. Glomus tumour rarely involves visceral organs. Glomus tumour involving the kidney is extremely rare and would not be encountered by most medical practitioners. In view of the rarity of glomus tumour of the kidney, its biological behaviour may not be know...

Monoclonal antibodies have been raised against rat kidney gamma-glutamyl transpeptidase (GGT). All five antibodies immunoprecipitate enzyme activity from solubilized kidney brush-border membranes, but not from hepatocellular carcinoma membranes. Three of the antibodies react immunohistochemically with brush-border membranes in sections of adult rat kidney, but none of the antibodies cross-react...

There has been continued interest in the nature of tumours arising in the kidney and suprarenal glands since Grawitz in 1883 described renal tumours arising from suprarenal rests, which he called hypernephroma. Others have described tumours varying from the hypernephroma type in cell structure, while yet maintaining in part the character of the true Grawitz tumour. The case which is presented h...

The so-called hypernephroma of the kidney is the most common ?f the renal neoplasms, but until recent years it was confused with carcinoma or sarcoma of that organ. According to Wilson,1 78 per cent, of all tumours of the kidney removed belong, to this class of new growth. In 1883 Grawitz 2 made the suggestion that these tumours Were derived from adrenal " rests," and to them he gave the name o...

Experimental renal cancer caused by ochratoxin A (OTA) in rats was first defined in the US National Toxicology Program (1989) and raised questions about any aetiological role in human urinary tract tumours. A review of histopathology in several rat kidney tumours from dietary OTA in recently described London studies, augmented by clinical immunohistochemistry for the first time for this mycotox...
