title: Pulmonary Metastatic Choriocarcinoma from a Burned-out Testicular Tumor.
abstract: A 54-year-old man was referred to our hospital because of progressive dyspnea. Chest computed tomography showed multiple nodular shadows with a peripheral ground-glass halo. His clinical condition continued to deteriorate with the development of progressive respiratory failure requiring mechanical ventilation. A histological examination of a transbronchial lung biopsy revealed choriocarcinoma. The patient died within nine days of admission. A histological examination of the right testis during an autopsy revealed a burned-out testicular tumor consisting of a teratoma and a fibrous scar. We herein report a rare case of pulmonary multiple metastatic choriocarcinoma originating from a burned-out testicular tumor.
