Solitary fibrous tumour of the pleura: an incidental finding.

We herein report a relatively rare case of a woman in her 30s with an incidental lung finding. She subsequently underwent resection for what was considered to be a solitary fibrous tumour of the pleura (SFTP). SFTPs are rare, slow-growing neoplasms from mesenchymal origin. These tumours are histologically characterised by proliferation of bland-looking spindled cells, arranged in a patternless pattern, with hypocellular and hypercellular areas set in a hyalinised stroma. Complete en bloc surgical excision (with margin negativity) is the treatment of choice for both benign and malignant SFTPs. Due to the possibility of local recurrence with benign and malignant SFTPs, clinical and radiological follow-up is recommended.
