Objective:
To report a case of primary germ cell testicular tumor that spontaneously remitted after metastasizing to the retroperitoneum, leaving histologically characteristic lesions of a fused tumor. The characteristic testicular ultrasound findings that permitted the diagnosis are described.
Methods/Results:
A 21-year-old male consulted for a retroperitoneal mass. The testes were normal on palpation. The testicular ultrasound showed a hyperechoic area with an acoustic shadow suspected as being a tumoral cicatrix. The histological analysis after orchidectomy revealed a mixed non-seminomatous germ cell tumor.
Conclusions:
Testicular ultrasound evaluation should be performed on all patients with retrosperitoneal germ cell tumor and normal testes on palpation. In the case described, there was good correlation between the ultrasound and the histological findings.
