Abstract

Parapharyngeal lipomas are rare benign tumors, accounting for less than 0.5% of all parapharyngeal space neoplasms. Its proximity to critical anatomical structures requires careful diagnostic evaluation and surgical management. We report a clinical case of a 69-year-old woman presenting to our hospital with progressive dysphagia, snoring and shortness of breath. Clinical examination and imaging studies revealed a parapharyngeal lipoma, which was successfully removed surgically. The diagnosis was confirmed by histopathological examination, and the patient recovered without complications or recurrence of the symptoms. This case highlights the importance of early diagnosis and appropriate surgical management for the treatment of lipomas in this rare location.
