Le synovialosarcome du poumon: à propos d’un cas et revue de la littérature

Pulmonary synovial sarcoma is a rare malignant tumor accounting for 10% of soft tissue sarcomas. It usually arises from the limbs and its occurrence in the lung is exceptional. We here report a clinical case of pulmonary synovial sarcoma in a 54-year-old man detected at a localised stage. This extremely rare tumor has a specific immunohistochemical phenotype. This provides strong support for diagnosis. Cytogenetic study confirms the diagnosis by showing the presence of specific translocation t (X; 18). This is highly characteristic of synovial sarcoma regardless of its anatomical location. This study highlights the anatomo-clinical, therapeutic and prognostic characteristics of this rare tumor often unknown to clinicians.
