THREE CASES OF HEMANGIOMA OF THE KIDNEY

Abstract

The first case was 38-year-old housewife with the chief complaint of recurrent gross hematuria for 10 years prior to admission. Pelvic examination revealed no evidence of the bleeding or disease.
The second case, 64-year-old man, was admitted with gross hematuria and right flank pain. This patient had noted hematuria of 3 weeks' duration 4-1/2 years previously. Intravenous pyelogram showed some irregularity of the middle calyx on the right side.
The third case, 27-year-old woman, was admitted complaining of hematuria. She had eight episodes of gross hematuria for 5 years. Intravenous and retrograde pyelograms were repeated and found to be normal.
In three cases, transfemoral aortograms were taken, and they all showed a localized pooling-like shadow in the tumor area. Nephrectomy was performed in these cases, and pathological diagnosis was hemangioma of the kidney.
Eighteen cases of hemangioma of the kidney are collected in the Japanese literatures including our three cases, and some clinical and pathologic observation are given. Put, if more exhaustive examination of the kidney were made, more cases of so-called essential hematuria could be found to be due to hemangioma, and study of aortogram may prove to be of great value in the diagnosis of hemangioma of the kidney.
