Background: Gonadoblastoma (GB) is regarded as an in situ form of germ cell tumor in dysgenetic gonads, and 30% of patients with GB develop a dysgerminoma/seminoma tumor.
Objective: Determine whether OCT3/4 and β-catenin are expressed in dysgenetic gonads before GB development and whether TSPY participates in the OCT3/4-β-catenin pathways in the malignant invasive behavior.
Methods: dysgenetic gonads of Disorders of sex differentiation (DSD) patients with mixed gonadal dysgenesis were analyzed by immunohistochemistry and immunofluorescence for comparison with GB and dysgerminoma/seminoma.
Results: Our results suggest that the development of GB is secondary to the interaction of OCT3/4 and TSPY, that β-catenin does not participate in this process.
Conclusions: The use of this biological markers detects the potential high risk gonads.
