Parapharyngeal Space Pleomorphic Adenoma: A Rare Case Report and Review of the Literature

Parapharyngeal space tumors are rare, accounting for less than 1% of all head and neck neoplasms [1]. Pleomorphic adenomas, although common in the salivary glands, are infrequent in this location. We report a case of a 45-year-old woman presenting with a parapharyngeal mass revealed by progressive dysphagia and a sensation of a foreign body in the throat. Magnetic resonance imaging (MRI) demonstrated a well-circumscribed mass arising from the deep lobe of the parotid gland and extending into the parapharyngeal space. Complete surgical excision via a transcervical approach was performed without complications. Histopathology confirmed the diagnosis of pleomorphic adenoma. We discuss the diagnostic and therapeutic challenges of these tumors and review the relevant literature.
