Pleomorphic adenoma (PA) is a benign tumor characterized by slow-growing mixed tumors in the craniofacial area. It is relatively common in salivary glands; however, PA of the nasal cavity, which arises in the minor salivary glands, is rare. We present the case of a large PA in the nasal cavity of an adult immunocompetent woman with nasal obstruction and intermittent epistaxis. Based on preoperative radiologic examinations, she was misdiagnosed with an inverted papilloma. Endoscopic resection was performed under general anesthesia. Pathologically, the patient was confirmed to have PA, which has great cellularity and few stromal components. No complications or recurrences during the 1-year follow-up period were observed.
