BURNED-OUT TUMOR OF THE TESTIS: CASE REPORT

Introduction: Burned-out testicular tumor is a rare entity. The term "burned-out" tumor of the testis describes a spontaneously and completely regressed testicular tumor which presents by its metastases to retroperitoneum, mediastinum, lymph nodes such as supraclavicular, cervical and axillary. This condition is different and less common from the primary extragonadal germ cell tumors. Many pathologists are not familiar with the findings that support a diagnosis of "burned-out" primary in a patient with metastatic germ cell tumor. We report 2 cases of burned-out testicular tumors to illustrate the clinical, radiological and histopathological features. Burned-out testicular tumor must be considered in a patient with retroperitoneal lymph node involvement and histology of germ-cell tumor in the absence of palpable testicular tumor. Metastases should be treated according to the histology and clinical stage of the tumor. Radical orchiectomy must be performed because of the high rate of persistent testicular tumor.
