History: A three-year-old boy underwent orchiectomy for a cystic scrotal mass. Microscopically, the rete testis was found to be markedly distorted by cystic dilatation which compressed the adjacent seminiferous tubules (Figs. 1, 2). The cystic rete lining was of low cuboidal epithelium (Fig. 3).
Diagnosis: Cystic dysplasia of the testis
