“…Fine-needle transthoracic aspiration cytology is usually inconclusive because of the presence of acellular and hypercellular portions in the tumour 5. Alternatively, undiagnosed thoracic tumours may first be evaluated by video-assisted thoracoscopy 1. While smaller tumours (<10 cm) have been successfully removed using video-assisted thoracoscopic surgery with fewer postoperative complications and shorter hospital stays, thoracotomy is the preferred method of resection for larger tumours 5 7.…”

Solitary fibrous tumour of the pleura masquerading as catecholamine-secreting paraganglioma

SUMMARYA 33-year-old African-American woman presented with left-sided chest pain for 2 months before admission. Physical examination revealed no breath sound in the left chest and CT scan of the chest showed total obliteration of the left pleural cavity. The patient also had hypertension and elevated urinary metanephrines, leading to a tentative diagnosis of a catecholaminesecreting paraganglioma. MRI revealed a large, heterogeneous soft tissue mass that occupied the entire left chest cavity, causing displacement of the heart and mediastinal structures to the right. Through a left thoracotomy incision, a tumour weighing 2790 g was removed along with a small portion of adherent lung. The tumour was positive for CD34 but negative for S-100, keratin, desmin and progesterone-receptor, which is consistent with pathological diagnosis of a solitary fibrous tumour of the pleura. The patient remains symptom free 4 years after the operation. BACKGROUND

“…Solitary fibrous tumours of the pleura (SFTP) are rare primary tumours of the pleura 1. They arise from mesenchymal tissue underlying the mesothelial layer of pleura and are benign approximately 80% of the time 2.…”
