The aim of this study is to describe the clinicopathological characteristics of intranasal pleomorphic adenomas (PAs), as well as the role and outcomes of endoscopic endonasal resection. A retrospective review of the clinical data from patients with PA of the nasal cavity who were treated by the authors at three tertiary medical centers between June 1998 and December 2019. A total of five patients with PA were found. Three patients were male, two were female and their mean age was 62.2 years. All cases were resected “en bloc” with endoscopic endonasal approach. No evidence of disease was observed during a mean follow-up of 10.6 years. No case presented with malignant transformation into carcinoma ex-PA. PA of the sinonasal tract and the nasopharynx is difficult to diagnose due to nonspecific clinical and radiological findings. Endoscopic endonasal approaches can be considered the gold standard in the treatment of these tumors and provide excellent visual control of the surgical field and clear margins.
