[Burned-out testicular tumor].

Burned-out testicular tumour is an uncommon entity defined by the spontaneous regression of the testicular tumoral site after spread to metastasis, leaving behind a scarring lesion with typical histological changes. This paper reports one case of burned-out testicular tumour diagnosed and treated initially as an embryonic carcinoma with areas of extragonadal malignant immature teratoma that after nine years of follow-up reveals the primary testicular site. Physical examination and detailed ultrasound study of the testes is of the greatest significance in stem cells tumours with extragonadal location, given the prospect of identifying the primary testicular lesion as a burned-out tumoral site and performing radical treatment of these tumours.
