Renal Tumours

The responsibilities of the radiologist in the diagnosis of urinary tract neoplasms are discussed: a strong plea is made for the routine use of pyelography in all cases in which renal tumour is suspected, and it is suggested that too much reliance is placed on the excretion method alone. From the radiological viewpoint, renal tumours may be considered in the following three groups: (1) Parencymal tumours. (2) Tumours of renal pelvis. (3) Extrarenal tumours resembling renal tumours on clinical examination. The radiological signs which may be found in each group are described in detail, including the signs from plain radiography, instrumental pyelography, and excretion urography. The significance of non-excretion in small renal tumours receives attention. It is suggested that this is a sign of renal vein neoplastic thrombosis. The characteristics of osseous metastases from carcinoma of the kidney are considered with illustrative examples. Neoplasms of the ureter and their differential diagnosis are considered.

The Difference

Attention is called to the difference between the pathologist's and the radiologist's point of view. The reasons for this difference are discussed with special emphasis on renal tumours. Classification of renal tumours. The first main groups are innocent and malignant. Are these really clear-cut or do they blend into one another? The commoner innocent renal tumours are adenoma, fibroma, myoma, lipoma, and angioma. These are rarely of any clinical importance but adenoma is a possible source of hypernephroma. Many elaborate classifications of cancer of the kidney have been proposed but the following four groups are sufficient for most puposes: Carcinoma, hypernephroma, sarcoma, and teratoid tumours. Much the commonest malignant renal tumour in adults is the hypernephroma, thought by Grawitz and others to be derived from ectopic adrenal rests. There is still no agreement concerning their origin but three views are held at the present time: ( a) All are carcinoma of renal tubules. ( b) Some are derived from renal tubules and some from ectopic adrenal. ( c) All are formed from adrenal tissue. These views are discussed with special reference to material in St. Mary's Hospital Museum, and it is suggested that the first view is the most probable although the second cannot be excluded. The teratoid tumours are the commonest in infants and swine. The differences between them and hypernephromata are described. The renal Pelvis, ureter, and bladder all have tumours of the same type and can conveniently be considered together. Connective tissue tumours, both innocent and malignant, are very rare. Papilloma and carcinoma are rare in the pelvis and ureter, but commoner in the bladder. The relation between these two tumours is discussed.

The article presents the clinician's view on general diagnostic and differential diagnostic approaches when analyzing data of the urine test in patients with nephrological, therapeutic and urological pathology. Features of the urinary syndrome are examined in detail depending on the presence, degree and severity of haematuria, leukocyturia, proteinuria, cylindruria in various diseases. Moments of diagnosis and clinical examination of patients with urolithiasis, kidney and urinary tract tumors, urinary tract tuberculosis, renal vascular anomalies, cystic dysplasia, and nephroptosis are described in detail in addition to traditional chronic kidney diseases (glomerulonephritis, pyelonephritis, interstitial nephritis).

Microscopic Diagnosis

The broadest application of transmission electron microscopy (EM) in diagnostic medicine is the identification of tumors that cannot be classified by routine light microscopy. EM is useful in the evaluation of approximately 10% of human neoplasms, but the extent of its contribution varies considerably. It may provide a specific diagnosis that can not be reached by other means, but in contrast, the information obtained from ultrastructural study of some 10% of tumors does not significantly add to that available from light microscopy. Most cases fall somewhere between these two extremes: EM may correct a light microscopic diagnosis, or serve to narrow a differential diagnosis by excluding some of the possibilities considered by light microscopy. It is particularly important to correlate the EM findings with data from light microscopy, clinical examination, and other diagnostic procedures.

Characteristic Features

Abstract Intravascular papillary endothelial hyperplasia is a benign intravascular process thought to arise from an organizing thrombus. The lesion may present clinically as an abnormal mass and, depending on the location, may be confused with benign or malignant neoplasms. It has been described in a variety of locations. Involvement of the renal vein by papillary endothelial hyperplasia is extremely rare, with only 4 cases reported in the literature. We describe 2 additional cases. In both cases, the radiologic examination revealed a well-circumscribed mass in the hilar region of the kidney, which was considered to be a renal neoplasm. Nephrectomy specimen in each case revealed characteristic features of intravascular papillary endothelial hyperplasia. It is suggested that intravascular papillary endothelial hyperplasia should be included in the differential diagnosis of a hilar renal mass.
