Plasmacytoid myoepithelioma: Diagnostic algorithm and a tailored therapeutic protocol for a geriatric individual

Plasmacytoid myoepithelioma (PM) is an exceedingly rare tumour, which often arises in the minor salivary glands. An 81-year-old male presenting with a massive growth occupying the entire palatal vault was operated by facial translocation approach. Histologically, a well-encapsulated tumour composed of numerous plasmacytoid myoepithelial cells arranged in an organoid pattern could be elicited. Diffuse immunoreactivity to pan-cytokeratin and glial fibrillar acidic protein pointed to a myoepithelial origin of the tumour, and low labelling index of Ki-67 indicated its benign nature. A conservative surgical procedure bearing in mind the age of the patient and ruling out other closely mimicking salivary gland tumours by immunohistochemistry highlights the importance of a tailored surgicopathological approach in geriatric patients to reduce post-operative morbidity.
