Regressed testicular germ cell tumour in a post-pubertal male

Testicular germ cell regression is a rare, generally metastatic phenomenon which describes the spontaneous, complete, or partial regression of a testicular germ cell tumour. As a result, studies have focused on defining specific histopathological criteria to establish if the resected testis is the primary source of the germ cell tumour. There are few publications which describe its presentation in the absence of distant metastases with elevated tumour markers and suspicious findings on testicular ultrasound. We present the clinical presentation and radiological features of a non-metastatic regressed testicular germ cell tumour following scrotal trauma in a post pubertal male.
