Journal Title: Journal of Oral Medicine, Oral Surgery, Oral Pathology and Oral Radiology - Year 2018, Vol 4, Issue 1
Abstract
Myoepitheliomas are rare benign salivary gland tumours almost exclusively composed of cells exhibiting myoepithelial differentiation These tumours are likely to be underdiagnosed as they are rare and tend to be morphologically diverse Pleomorphic adenoma basal cell adenoma and myoepithelioma usually lie on a continuum with many overlapping features In myoepithelioma the neoplastic myopeithelial cells can be spindly plasmacytoid hyaline epitheliod clear or oncocytic or combination of the above Fine needle aspiration cytology FNAC in such cases may have limited diagnostic value but nonetheless is important to rule out unsuspected malignancies We present a case of a forty five year old female with a growth on the hard palate The aspirates in our case very closely resembled cellular pleomorphic adenoma However detailed histopathological examination of the excised specimen along with relevant immunohistochemical markers proved it to be a case of plasmacytoid myoepitheliomaWe report this case to highlight the cytological features and differentials of this rare tumour which can also be confirmed on histopathologyKeywords Hard palate Pleomorphic adenoma FNAC Myoepithelioma Plasmacytoid
