Pleomorphic Adenoma in the Nasal Cavity: Case Report and Review of Literature.

Pleomorphic adenoma (PA) represents the most frequently occurring benign tumor within both major and minor salivary glands. However, in rare instances, nasal PA is an epithelial-derived borderline tumor, often originating from the nasal septum. Diagnosis usually relies on histopathological analysis. Under general anesthesia, these rare nasal tumors can be completely resected via endoscopic surgery. This article reports a case of PA originating from the nasal septum in a 49-year-old patient presenting with nasal congestion, along with a brief review of the current literature. The diagnostic nasal endoscopic examination showed a pink neoplastic mass in the left nasal cavity. Subsequent radiologic examination demonstrated a soft tissue mass in the anterior part of the nasal septum. After complete resection under nasal endoscopy, histopathological examination confirmed it as PA. Fortunately, no related complications occurred perioperatively and postoperatively. After surgery, performing a thorough examination with nasal endoscopy and scheduling regular follow-ups are crucial steps to prevent local recurrence.
