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.

Objective: To present a case of carcinoma ex pleomorphic adenoma in the parapharyngeal space and discuss its management.   Methods: Design:            Case Report Setting:           Tertiary Government Teaching Hospital Subjects:         One   Results:  A 40-year-old male patient with dysphagia for three months and a left-sided mucosa-covered oropharyngeal mass was found to have a prestyloid parapharyngeal lesion on CT Scans. Fine Needle Aspiration Cytology (FNAC) revealed a pleomorphic adenoma. With a past history of parapharyngeal pleomorphic adenoma excised transorally three years before, the present mass was excised by mandibular swing approach. Post-operative recovery was uneventful, but the final histopathological report was carcinoma ex pleomorphic adenoma.   Conclusion: Malignant transformation should be suspected in recurrent salivary tumors in the parapharyngeal space. Provided there was truly no pre-existing malignant focus in the originally-excised tumor, and that early recurrence was not due to inadequate initial excision, this patient had a rare condition where the same tumor underwent malignant transformation within 3 years only. To the best of our knowledge, such an early transformation to malignancy of a minor salivary gland tumor of the parapharyngeal space has not been reported in the English literature.   Keywords: carcinoma ex pleomorphic adenoma, pleomorphic adenoma, carcinoma,  parapharyngeal space, malignant, transformation, minor salivary gland tumor,  mandibular swing

Important Structure

<p class="abstract">The parapharyngeal space is an inverted triangular pyramid. Parapharyngeal space masses account for 0.5% of all head and neck tumours and the majority is benign. Minor salivary gland tumour is a rare entity. A 75 years old female presented with a mass left side soft palate, per operatively mass of size about 6×3 cm was deeply extending to left parapharyngeal space and excised through transoral approach which came out to be pleomorphic adenoma of minor salivary gland on histopathological examination. Although external approach should be preferred due to important structure in vicinity but transoral approach can be used in selective cases.</p>

High Index Of Suspicion

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.

Pleomorphic adenoma provides as much as 40-70% of tumors in the minor salivary gland with the palate being the most frequent area engaged. Head and neck tumors in parapharyngeal space amount to less than 1%. We share a case of pleomorphic adenoma primarily arising in parapharyngeal space. This report highlights clinical features, pathology, radiological findings, and treatment of this tumor.
