Parapharyngeal space tumors (PPS) are rare. They represent less than 1% of all head and neck tumors. They are of various histologies. Pleomorphic adenomas originating from the parotid (prestylian parapharyngeal space) are the most frequent. We report the case of a 50-year-old patient treated for a pleomorphic adenoma (PA) of PPS. His initial complaints were apnea and dysphagia. The correct diagnosis was preoperatively suspected by magnetic resonance imaging (MRI). The surgery was carried out using two approaches: transoral and cervical transparotid approaches. Definitive histology was consistent with encapsulated pleomorphic adenoma. In the present work, we reviewed clinical, radiological, and histological features of parapharyngeal space tumors. We tried to summarize the common surgical approaches. The chosen approach is, in fact, scheduled taking into account several parameters including tumor volume and purpose of the surgery.

Introduction.De novopleomorphic adenomas in the parapharyngeal space are rare and cause difficulties in its surgical management. We report the largestde novopleomorphic adenoma arising from the parapharyngeal space and discuss its surgical management.Presentation of Case. A 34-year-old male presented with a giantde novopleomorphic adenoma arising from the parapharyngeal space, which was initially misdiagnosed as an impacted wisdom tooth. Measuring8.4×6.5×3.9 cm in size and weighing 87.3 g, this is the largest primary salivary gland tumour arisingde novofrom the parapharyngeal space reported in the literature, presenting challenges in its surgical management.Discussion. Parapharyngeal space tumours cause nonspecific symptoms and may be difficult to diagnose, which can allow the tumours to become very large and cause obstructive and compressive symptoms in an anatomically difficult area. A combined trans-cervical and trans-oral approach can be used to safely perform anen blocresection.Conclusion. We report the diagnosis and surgical management of the largest pleomorphic adenoma arisingde novofrom the parapharyngeal space reported in the literature.

Background Carcinoma ex-pleomorphic adenoma of the parapharyngeal space is an exceedingly rare entity. Methods The clinical records of two patients with primary carcinoma ex-pleomorphic adenoma of the parapharyngeal space surgically treated at two different centers were retrospectively analyzed. Results Despite ultrasound-guided fine-needle aspiration cytology and magnetic resonance imaging, the correct diagnosis was preoperatively missed in both cases. Excision was obtained through a transcervical-transparotid approach in 1 case and a minimally-invasive endoscopic-assisted transcervical approach in the other. Definitive histology was consistent with intracapsular carcinoma ex-pleomorphic adenoma. Adjuvant radiotherapy was performed in the case with macroscopic malignant degeneration; both patients are alive and free from disease 36 months after surgery. Conclusions Carcinoma ex-pleomorphic adenoma of the parapharyngeal space is a rare disease, and definitive diagnosis may be challenging. Surgery is the mainstay of treatment, but adjuvant radiotherapy also may be required in the presence of specific risk factors.

Parapharyngeal space tumors are rare and constitute only 0.5–1.0% of head and neck tumors. Minor salivary gland tumor is still rare in parapharyngeal space. We are reporting a case of pleomorphic adenoma of minor salivary gland of parapharyngeal space. A 42-year-old female presented with a history of mass in the oropharynx for 3 years. She presented with “hot potato voice” and dysphagia. CECT and MRI were done, showing large parapharyngeal space tumor. FNAC was suspicious for tumor of nerve cell origin. Tumor was excised using “paramedian mandibulotomy with mandibular swing approach”. Histopathological examination was inconclusive, suggesting possibility of extraskeletal myxoid chondrosarcoma, solitary fibrous tumor, neurogenic tumor. On immunohistochemistry, tumor was positive for cytokeratin, EMA (dim), S-100, and P 63 and negative for SMA thus proving the case as myoepithelial cell-rich pleomorphic adenoma.

Methods: Tumors originating in the parapharyngeal space are uncommon. During the period of January 1999 to December 2008. Among them 34 patients underwent surgery for parapharyngeal space tumors at the Department of Otolaryngology and Head Neck Surgery, Chittagong Medical College Hospital. Results: Ninety one percent of the parapharyngeal space neoplasms were benign; 9% were malignant. Majority of the benign tumors were salivary gland origin followed by neurogenic tumors. The use of FNAC, computed tomography scan and ultrasound imaging are very useful to assess the location, size, vascularity, tissue origin and relation of parapharyngeal space tumors to surrounding anatomical structures. Conclusion: This information was essential in planning surgical approaches and predicting the prognosis. Details of the management, morbidity, and outcome of these patients were presented.

ABSTRACT Parapharyngeal space (PPS) lesions account for only 0.5% head and neck tumors and the majority of the minor salivary gland tumors are malignant. We report a case of pleomorphic adenoma of minor salivary gland in PPS as this is of a very rare occurrence. High index of suspicion and an adequate clearance of the tumor with a cuff of surrounding dispensable normal tissues are the key to successful treatment of such tumors.

Objective Primary parapharyngeal space (PPS) tumors are one of the most challenging head and neck tumors to diagnose and treat. We analyzed our experience in patients with PPS tumors who were treated in our hospital over 13 years. Methods We retrospectively reviewed 16 patients with PPS tumors between 2006 and 2018. The study included clinical symptoms, histological types, surgical approaches, adjuvant therapies, postoperative complications, and prognosis. Results The mean age of the patients was 49.63 ± 17.03 years. A palpable neck mass (56.3%) was the most common symptom. In our series, 78.6% of the tumors were benign, and of these, schwannomas were the most common (6/14, 42.9%). Three surgical approaches were used in our patients, including transmandibular (57.1%), transcervical (21.4%) and transparotid (21.4%) approaches. Few complications were reported, including hoarseness and numbness. Adjuvant therapy was administered depending on pathological parameters of the tumors. No recurrence was observed during a mean follow-up of 60.6 months in patients with malignant tumors. Conclusions Radiological studies of PPS tumors are essential for diagnosis and surgical planning. Excision of PPS tumors using appropriate surgical approaches provides good outcomes.

OBJECTIVE: To describe clinical and demographic characteristics of the parapharyngeal space tumors and assess surgical approaches used to treat them at our institution. METHODS: A retrospective and descriptive study of the parapharyngeal space tumors, excluding paragangliomas, treated from June 1991 to October 2002 in a cancer center. The study population included 21 patients, 8 men and 13 women, average age of 41 years (range, 20 to 70 years). Fine needle biopsy was done in 5 (24%) patients. Computed tomography (CT) was performed in all patients, and only a few required magnetic resonance image (MRI). RESULTS: Surgical approaches included transcervical alone or in combination with parotidectomy, transoral, or transmandibular (mandibular swing) approach. Laminectomy and segmentary approaches were also performed in 1 patient each. Sixteen (76%) patients had benign lesions and 5 (24%) had malignant tumors. Neurogenic tumors represented 57% of all tumors. Mean tumor size was of 6.7 cm (range, 3 to 11 cm). Six (29%) patients received adjuvant radiotherapy. Complications occurred in 6 (29%) patients, 4 (19%) of which were nervous injuries associated with peripheral nerve sheath tumors. Median disease-free follow-up survival was 33 months (range, 2 to 184 months) despite being an heterogeneous group of histologies. CONCLUSION: Parapharyngeal space is a rare location for head and neck tumors. Cervical approach should be the first choice for large tumors; transoral approach is reserved for tumors less than 3 cm. Conversion to mandibular swing approach when the cervical approach is not offering proper exposure for tumor resection is indicated. Preoperative histologic diagnosis is not required. Nevertheless, CT scan should always be performed in order to exclude paragangliomas, distinguish prestyloid from poststyloid lesions, and to assess the extension of the tumor as well as its relationship with adjacent structures.
