Abstract:

Synovialosarcoma is a rare malignant tumour, accounting for 10% of soft tissue sarcomas. It usually develops in the limbs and its pulmonary location is exceptional. We report a clinical case of lung synovialosarcoma in a 67-year-old man discovered at a localized stage. This extremely rare tumour, presents an intracanal extension and a wide base of pleural implantation. Multidisciplinary collaboration was ensured: the patient was operated on in two stages, two days apart. The particular immunohistochemical phenotype strongly contributes to the diagnosis. Through this observation, we emphasize the anatomo-clinical, therapeutic and prognostic characteristics of this rare tumor often overlooked by clinicians. We demonstrate the interest of a multidisciplinary collaboration in the management of this tumour.
