Rare sequelae of a testicular tumor: A ‘burnt-out’ tumor

Introduction: Testicular tumors typically present as a palpable lump. Some tumors have been known to spontaneously regress, thus have been referred to as ‘burnt-out’ tumors or vanishing tumors. Case Report: A 28-year-old male was seen in urology clinic with clinical findings of a small atrophic left testis, with a prior history of a painful left testicular lump not responsive to antibiotics, which had spontaneously resolved. Ultrasound scan revealed an initial solid testicular lesion of 19x12x10 mm with internal vascularity, which upon repeat ultrasound scan two months later found a 12-mm coarse calcification and a hypoechoic region, but regression of the initial solid lesion. The diagnosis of a burnt-out tumor was made and he underwent urgent radical orchidectomy and prosthesis insertion. Computed tomoraphy (CT) staging scan showed significant paraortic lymphadenopathy, therefore the patient further underwent chemotherapy. Treatment has been successful and the patient is progressing well with no complications. Conclusion: The diagnosis of a burnt-out testicular tumor is an important differential to consider in patients with spontaneously regressing testicular lumps, abnormal findings on ultrasound scan and subsequent presentation of testicular atrophy of unknown cause. This diagnosis should also be considered in patients with secondary metastatic tumors of unknown primary (This page in not part of the published article.)
