A 56-year-old male underwent a right extrapleural pneumonectomy for malignant pleural mesothelioma. Two years after the operation, an intrathoracic mass was suspected of recurrence by imaging, however, biopsy revealed that the mass was actively proliferating liver tissues. We discussed this condition in terms of ectopic liver proliferation.
