A 63-year-old male was admitted to our Department for incidental radiological finding of an enormous mass, occuping the whole left hemithorax. The CT-scan shows a giant lobulated tumor, with heterogeneous density causing a complete lung atelectasis (Figure 1
). A left postero-lateral thoracotomy was performed: a huge capsulated tumor with a pedicle from the diaphragmatic pleura was successfully resected after legation and sectioning of the peduncle (Figure 2). Size of the tumor was 19 cm x 18 cm and weighed 2,700 gm. Post-operative course was uneventful: the lung gradually re-expanded and the patient was discharged after 7 days with a normal chest X-Ray. The pathological diagnosis of the tumor was localized fibrous tumor of the pleura. Histology demonstrated a benign behaviour: low mitosis rate (0-3 MF/10 HPF) and Ki67 < 3%. Short spindle cells resulted positive for for CD-34, vimentin, -catenin and negative for S100 protein, CD117, and actin. No recurrence was observed after a 3-year period.
