A Rare Case of Testosterone-Producing Non-Seminoma Germ-Cell Testicular Cancer.

Androgen secretion by testicular germ-cell tumors (GCTs) appears to be markedly rare and likely underreported in the literature. This case study highlights a patient with such a rare tumor, underscoring a notable and yet easily avoidable diagnostic oversight in one of the most prevalent cancers among men. We advocate for increased vigilance and the inclusion of specific symptomatic screening for hyperandrogenism of select patients in existing guidelines and, where appropriate, the implementation of standardized hormonal laboratory analyses in both pre- and post-orchidectomy assessments. These measures could enhance the reporting of cases, standardize care, and improve understanding of the underlying mechanisms of these rare tumors. Finally, future studies should explore the implications of androgen secretion for the prognosis and treatment of GCTs.
