Parapharyngeal lipoma: a case report.

A 44-years-old male presented with right infraauricular swelling. It had been four months since he was aware of the mass. He had not felt any pain or tenderness. Computed tomograpy demonstrated a homogenous, regular surfaced mass located in the prestyloid and poststyloid parapharyngeal space. Its density was concordant with lipomatous tissue, so it was considered to be an infiltrating parapharyngeal lipoma. Postoperative diagnosis revealed a similar result. We believe that computed tomograpy is an effective method of diagnosing parapharyngeal space tumors and tansparotid approach for this localization is very useful for both preserving facial nerve functions and exposing the mass clearly. We report a case of parapharyngeal lipoma slightly invading the deep lobe of the parotid gland.
