CYSTIC DYSPLASIA OF THEE TESTIS ASSOCIATED WITH MULTICYSTIC DYSPLASIAOF THE KIDNEY

A child with cystic dysplasia of the testis (CDT) that presented as a solid mass by ultrasound imaging is reported. The child also had ipsil ateral multicystic dysplasia of the kidney (MCDK). A search of the lit erature revealed that unilateral renal agenesis (URA) is commonly asso ciated with CDT. It is possible that CDT, MCDK, and URA share a common pathogenesis. Cystic changes in the epididymis were found in the pati ent and might be more frequently associated with CDT than previously r eported. CDT should be considered in the differential diagnosis of a s olid testicular mass detected by ultrasound. (C) 1998, Elsevier Scienc e Inc. All rights reserved.
