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.
