Solitary fibrous tumour of the pleura arising in a pulmonary cavity

Solitary fibrous tumour of the pleura (SFTP) is a rare neoplasm. Moreover, cavity formation associated with SFTP is extremely rare. To our knowledge, only one such case has been previously reported. AbstractSolitary fibrous tumour of the pleura (SFTP) arising in a cavity is extremely rare. A 66 ‐year‐old Japanese male presented with an abnormal shadow on his chest X‐ray. Chest computed tomography showed a cavity of approximately 18 mm in diameter between the upper and lower lobes that contained a solid nodule within. Under the thoracoscope, the peduncle cystic tumour was removed wi th sufficient surgical margin. Macroscopically, a tumour of about 15 mm in diameter arose in the cystic cavity. Immunohistochemical stains were positive for CD34, bcl‐2, and signal transduction and activator of transcription 6 (STAT6) but negative for smooth muscle actin (SMA), desmin, and epith elial membrane antigen (EMA), and a diagnosis of SFTP was made. The patient remains well without recurrence or any complications at two and a half years after the operation. SFTP should be considered when a tumour arises in a cavity existing in an interlobar space. It is important to determine wheth er the tumour is pedunculated or sessile during surgery and to perform the appropriate surgical procedure.
