<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>

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.

Recommended Treatment

Pleomorphic adenoma is the most common neoplasm in major and minor salivary glands. It constitutes approximately 90% of all benign salivary gland lesions and the parotid is the most affected location. When the minor salivary glands are affected, it mostly occurs at the junction of the hard and soft palates. The diagnosis is complex because of the great histological variety and biological behavior of this tumor, a histopathological examination being essential. The recommended treatment is surgical excision. For lesions located superficially in the parotid gland, superficial parotidectomy - identifying and preserving the facial nerve - is necessary. Lesions in the palate or gums sometimes demand a margin of safety, being excised below the periosteum, including the overlying mucosa. With correct surgical removal, the prognosis is excellent. The aim of this study is to report a case of an unusual minor salivary gland pleomorphic adenoma in the hard palate, describing the most important aspects of this pathology.

Chondroid Metaplasia

Salivary gland tumors are rare among all head and neck tumors. Pleomorphic adenoma (PA) is the most commonly seen subtype, and 85% of the cases are located in the parotid gland. PA may very rarely be seen in minor salivary glands. Minor salivary gland PAs are mostly located in the hard and soft palates. Nasopharyngeal PA is very rare, and a total of 8 cases have been published to date. In this case report, a 51-year-old female patient who had nasopharyngeal PA with chondroid metaplasia is presented, and we review the relevant literature.

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

We are presenting a rare case of Pleomorphic adenoma cheek. A 60 year old female patient presented with a painless swelling in right cheek since 4 years. On examination a well circumscribed, soft to firm 1.5x1cm mass was palpable. FNAC revealed Pleomorphic adenoma. The diagnosis was confirmed by histopathological examination after excisional biopsy of tumor. Key words: pleomorphic adenoma, cheek, minor salivary gland

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.
