[Gonadal tumors in the testicular dysgenesis syndrome].

Morphological study of the gonads in 84 patients with the testis dysgenesis syndrome demonstrated the presence of the tumours in 26 (31%) of cases. They were mostly microscopic, benign, could affect both gonads simultaneously, and, in asymmetrical differentiation of the gonads, the connective tissue band as well. Two types of the tumours were revealed: gonadoblastomas (different variants) and dysgerminomas. No specific clinical signs of the tumour changes of the gonads accompanied the syndrome under study.
