Myoepithelioma of the Posterior Oropharyngeal Wall: A Difficult Diagnosis

Myoepithelioma is an extremely rare tumour subtype and diagnosis is based on a wide variation of cellular morphology. They are poorly characterised in terms of their clinical behaviour, histopathological appearance and immunochemical profile, which makes their diagnosis and the onward management of a patient challenging. We present a case where the lesion was initially thought to be a paraganglioma, but following a second histological opinion was found to be a myoepithelioma. To the best of our knowledge, this is the first reported case of a myoepithelioma arising from the posterior oropharyngeal wall.
