RESUMEN
@#<p><strong>OBJECTIVE:</strong> To present a case of carcinoma ex pleomorphic adenoma in the parapharyngeal space and discuss its management.<br /><br /><strong>METHODS:</strong> <br /><strong>Design:</strong> Case Report<br /><strong>Setting:</strong> Tertiary Government Teaching Hospital<br /><strong>Patient:</strong> One<br /><br /><strong>RESULTS:</strong> 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. <br /><br /><strong>CONCLUSION:</strong> 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 three 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.</p>
