Hemihypertrophy as possible sign of renal cell carcinoma.

In infants and children there is a well-recognized association of hemihypertrophy with visceral malignancies, including those of the kidney as well as benign renal disorders. As a result of our report on an adult with segmental hemihypertrophy and renal cell carcinoma, we suggest that if this combination represents an association similar to that found in children, a radiographic-urologic evaluation is needed to diagnose renal neoplasms at an early stage, and to disclose the presence of treatable benign renal disease.
