The Silent Giant.

SFT is a rare spindle cell neoplasm arising mostly at pleural and in rare cases at extrapleural sites. Histology and immunohistology are diagnostic tools. It is crucial to consider SFT as differential diagnosis in pulmonary nodules since they often remain clinically silent until they reach large dimension and to proceed with curative resection without delay. It is essential to follow up patients for a long period of time as recurrence may occur.
