[Lipid cell variant urothelial carcinoma of the renal pelvis. A case report and literature review]

Abstract

There are many variants of urothelial carcinoma. One of the most infrequent is formed by cells with a lipid content and an adipose tissue appearance. Only 43 cases have been reported in the bladder, 2 in the renal pelvis and 1 case in the ureter. We present a third case in the renal pelvis; the patient is alive and free of disease 103 months post diagnosis.
