[Primary pulmonary synovial sarcoma: a report and diagnosis of 2 cases].

Synovial sarcoma is an extremely rare primary pulmonary tumor whose description is based on a limited number of cases. We report two cases diagnosed by thoracotomy. One patient was initially treated surgically, and a later recurrence was controlled by combined chemotherapy and a second operation after three years of monitoring. In the second case, surgery was imperative to treat massive hemoptysis and was followed by combined chemotherapy after diagnosis of lesions consistent with extrapulmonary metastasis.
