Undifferentiated metastatic carcinoma and myoepithelioma: two rare causes of hypervascular masses of the parapharyngeal space.
We report 2 unusual cases of hypervascular masses in the parapharyngeal space. The first case involved a poorly differentiated metastatic carcinoma of oropharyngeal origin that mimicked a carotid body tumor. The second case involved a highly vascular myoepithelioma located in the parapharyngeal space.
