A 60-year-old male presented with dyspnea and chest pain. He was referred with massive bulky mass. A mass in the left lung was observed using chest X-ray (Figures 1).  A computed tomography scan of the chest showed a mass on the left lung with complete lung collapse Figures 2 (A, B). The needle biopsy was performed and the case was diagnosed with solitary fibrous tumor. Subsequently, the patient underwent complete resected open thoracotomy. In our case, the mass dimension was 50 × 35 cm weighting 5.600 gr Figures 3 (A,B).
