Reporting a Rare Case of Plasmacytoid Myoepithelioma of Hard Palate

Myoepitheliomas are rare salivary gland tumours that make up less than 1% of all salivary gland tumours. The growth patterns may be solid, myxoid or reticular, and spindle-shaped, plasmacytoid, hyaline, transparent or epithelioid may be the component cells. Objective: Salivary gland myoepithelioma is exceedingly rare, representing just around 1-1,5 percent of all salivary gland tumours. Context: Small tumours of the salivary gland are infrequent, comprising 10-15% of all salivary neoplasms. Their frequent site is the parotid gland, and palatal salivary gland myoepithelioma is considered an uncommon organism. Once again, Plasmacytoid Myoepithelioma of the palatal salivary glands is sporadic, with only 15 cases reported to date. Case Description: A 51-year-old female patient with steadily rising palatal swelling is reported here. Myoepithelioma was indicative of FNAC’s cytological characteristics. The patient underwent comprehensive surgical excision of the lesion and the maxillary obturator was subsequently given to the patient after a month of patient follow-up where oronasal contact was present. Conclusion: In conclusion, salivary gland myoepithelioma are abnormal tumours with plasmacytoid variants that are still sporadic. They may be misdiagnosed because of their unusual variable growth patterns and also because of enhanced cellularity. Its appearance can clinically mimic pleomorphic adenoma, which hampers the right diagnosis. Medical relevance: This case study reinforces the need to alert dentists to the inclusion of myoepithelioma in elderly patients in the differential diagnosis of palatal swelling.
