Abstract

|
|
A case of angiolipomyoma with evidence of malignant transformation from a 50 year old housewife is reported. Clinical signs were intermittent colicky and dull flank pain for several years with palpable mass at the right costo-vertebral angle. Urinary findings were not remarkable. No evidence of tuberous sclerosis or adenoma sebaceum was present.
The removed kidney showed multiple discrete and deeply yellow tumor nodules
scattered throughout renal parenchyma and peripelvic fat tissue mimiking adenocarcinoma of the kidney. Palpation of the opposite kidney at the operation also showed nodularity. Histologically, the tumor consisted of admixture of proliferated blood vessels, smooth muscle cells and mature adipose tissue. The major part of. the tumor showed typical hamartomatous nature of angiolipomyoma, but at several areas, the tumor was quite cellular and monotonous with features of sarcomatous change. The sarcomatous element appeared to derived from smooth muscle cells.
