Temporal bone giant cell tumour: report of a second primary giant cell tumour of the temporal bone and infratemporal fossa

Temporal bone giant cell tumour: report of a second primary giant cell tumour of the temporal bone and infratemporal fossa. Objective: To report a second primary giant cell tumour (GCT) of the temporal bone and infratemporal fossa. Methodology: Medical records were analyzed in the context of the available literature. Results: A 30 year-old male developed a temporal bone GCT with infratemporal fossa extension 12 years after undergoing successful surgical treatment of a GCT of the femur. These tumours were histologically distinct, suggesting the development of a second primary GCT rather than metastatic disease. This case differs from prior reported cases by surgical approach. Complete removal was achieved but required resection of the zygomatic arch and dissection of all upper facial nerve branches. The patient is disease free after 3 years with acceptable functional and cosmetic results. Conclusion: Complete resection of GCTs of the temporal bone and infratemporal fossa is advocated. Surgical techniques that allow for visualization of the facial nerve and increase surgical access can enhance overall clinical success.
