Abstract:Pleomorphic adenoma (PA) is the most common benign tumor of the salivary gland, occurring approximately 80% in the parotid gland, 10% in the submandibular gland, and 10% in the small salivary gland or sublingual gland. Ectopic PA is relatively rare and can exist in soft tissues of the neck, lymph nodes, tongue, mandible, pituitary gland, mastoid bone, thyroid gland, parathyroid gland, nasal subcutaneous layer, and skin of the external auditory canal. There are very few reports of nasal root PA, and there is often no follow-up data on recurrence. In this case, the patient's nasal root PA has recurred multiple times, and there was no recurrence after the third complete mass resection, which is of great clinical significance.
