Hemangiopericytoma (HPC) was diagnosed in a 65-year-old man in 1991. Initially the tumor was located in the maxillary sinus. Resection was followed by multiple recurrences involving the infratemporalis fossa (ITF), the nasopharyngeal region, and the right tonsillar region. Over a 10-year-old period, the histology pattern remained unchanged. Multiple approaches, as described in the literature, were used for resection depending on the site of the recurrence. To data, no malignant structure has been identified. Pain and cranial nerve deficits (V2, V3) have been the main squeleae. This case points out the limitations of radical resection because of the difficulty of the approach to this anatomic region. CT scan must be performed to choose the best access route depending on the primary site of the tumor and its extension. |
