“…To the best of our knowledge, there is only one other report describing a GCT in this site. 1 Second, the tumor manifested clinically as Eagle syndrome, which is believed to be caused by an elongated styloid process.…”

“…11,12 Although GCTs are not uncommon in the head and neck area, they are rare in the parapharyngeal space, with only one previously documented case. 1 The tumor is typically benign and solitary, but may be multiple and, rarely, malignant. 7 There are 2 types of malignant GCTs: one is biologically malignant without a histologic correlate, and the other is biologically and histologically malignant.…”

“…8 The most effective treatment for GCT is wide local excision. 1,7 If the tumor shows any features of malignant potential, some authors recommend a regional lymph node dissection and radiographic evaluation for metastasis. 7 Recurrences are noted in 8% to 12% of GCTs with positive surgical margins.…”

Eagle syndrome includes elicitation of pain on swallowing, turning the head, or extending the tongue. The syndrome is thought to be caused by irritation of the glossopharyngeal nerve, most commonly caused by its impingement against an elongated styloid process. We present a rare case of a granular cell tumor presenting as Eagle syndrome. Granular cell tumors orignate from Schwann cells and are most common in the subcutaneous tissue of the head, neck, and oral cavity, especially the tongue. A granular cell tumor is typically benign and solitary, rarely malignant. The differential diagnosis, diagnostic algorithm, and treatment are presented.

The transparotid-cervical approach is the preferred procedure for most parapharyngeal tumors and can be combined with midline mandibulotomy for large vascular or selected malignant tumors. Recurrence after removal of pleomorphic adenomas is only 4%. Recurrent or persistent malignant disease is nearly always fatal. Perioperative mortality is zero, and morbidity is most often associated with cranial nerve neuropathy.

The parapharyngeal space, an area of complex anatomic relationships, is involved in a wide variety of benign and malignant neoplasms. Because primary parapharyngeal space tumors are rare, it is difficult to obtain surgical experience in this region. This paper reviews the anatomy, presentation, evaluation, surgical approaches, and pathologic features and complications reported in managing patients with parapharyngeal space neoplasms. Two surgical procedures have been used by the author to treat 44 tumors in the parapharyngeal space. The cervical‐parotid approach was used in 35 patients, and the cervical‐parotid approach with midline mandibulotomy was used in 9 patients. Of the 44 tumors, 32 were benign lesions and 12 were malignant neoplasms. Forty tumors were primary parapharyngeal space tumors, and 4 cases represented isolated metastases to parapharyngeal nodes. Recurrent tumors accounted for 12 of the 44 cases. Discussion of the indications, surgical technique, and select points pertinent to using these two operative procedures is based on the operative experience gained from these 44 patients. The use of these two operations resulted in low morbidity and provided a safe, efficacious approach to the management of all parapharyngeal space neoplasms encountered.

Granular Cell Myoblastoma of the Parapharyngeal Space

Abstract: A granular cell myoblastoma of the parapharyngeal space is presented. Although uncommon, this neoplasm of controversial origin must be considered in the differential diagnosis of all nonenhancing parapharyngeal space masses.
