Outsized tumours of the mediastinum are always present a challenge for the thoracic surgeon. This is a case report of a giant malignant Triton tumour occupying almost the entire right hemithorax. The patient presented in the accident and emergency (A&E) with severe dyspnoea. He referred a history of surgically excised fibromyxomatous sarcoma of the left lower limb with 2 local recurrences. The imaging studies revealed apart the giant neoplasm, total right lung atelectasis and pleural effusion. After diagnostic evacuation of the pleural effusion and bronchoscopy, the patient operated through a right postero-lateral thoracotomy; a giant well-encapsulated tumour not invading any anatomic structures or lymph nodes originated from the posterior mediastinum was excised radically. The patient recovered well and received radiotherapy after the operation for preventing local recurrence. © The Author(s) 2021.
