2 CASES OF TUMORS OF RENAL PELVIS

Abstract

Primary neoplasma of renal pelvis are rare, by statistical report of many authors formed it about 5-10 per cent of all renal tumors.
In Japan 201 cases of tumors of renal pelvis were reported till 1960. The classification of these tumors discussed by many authors and today the benign papilloma, that were previously diagnosed, were considered as carcinoma first grade. We present here statistically the histopathological diagnosis of reported cases and short history of 2 cases of transitional celled carcinoma of renal pelvis.
The (pathological) diagnosis of 201 cases are as follows.
Benign papilloma 68 cases
Malignant papilloma 28 cases
Papillary carcinoma 30 cases
Squamous celled carcinoma 30 cases
Transitional celled carcinoma 15 cases
Basalcell-carcinoma 4 cases
Adenocarcinoma 3 cases
not papillary carcinoma 1 case
Carcinoma simplex 1 case
Cancer of renal pelvis 4 cases
Sarcoma 1 case
Tumor of renal pelvis 2 cases
not described 14 cases
Case 1: 44 years old man, visited our clinic 25th May 1960 with complaint of asymptomatic haematuria since 1 month. By cystoscopical and roentogenological examination are diagnosed as tumors of left kidney. Nephrectomized kidney showed papillary tumor at renal pelvis and small stone formation. Histological diagnosis: papillary transitional celled carcinoma.
Case 2: 66 years old woman suffered from slight abdominal pain of one week duration at light side. By another doctor found out swelling of right kidney and visited our clinic 10th May 1960. Pyelogram showed obstruction of right ureter and no image of right pelvis. Under the diagnosis of renal tumor nephrectomy performed.
Histopathological diagnosis: papillary transitional celled carcinoma of renal pelvis.
