A case of myoepithelioma with cyst‐like structure in the maxilla.

Background: Myoepithelioma is a rare type of salivary gland tumor that mainly occurs in the parotid glands and palate. Case presentation: A 43‐year‐old woman presented with swelling and pain in the right maxillary molar. We performed enucleation and curettage under general anesthesia. The tumor was cyst‐like. Histopathological examination revealed nests of tumor cells diffusely interspersed within fibrotic connective tissues. A few cells were positive for cytokeratin AE1/AE3, α‐SMA, GFAP, and vimentin; S‐100 protein and calponin were also positive. Final diagnosis was myoepithelioma. Conclusion: Over 7 years after the surgery, the postoperative course was good, with no recurrence of the tumor. [ABSTRACT FROM AUTHOR]
