Description
Summary:Myoepithelioma is an extremely rare tumour subtype and diagnosis is based on a wide variation of cellular morphology. FNAC specimens do not always suffice for a definitive differential diagnosis which depends on histology and immunohistochemistry of the lesion. Case Presentation. A 54-year-old female came to our attention with dysphagia and dyslalia of 6-month standing. Ear, Nose, and Throat (ENT) examination revealed a voluminous mass on the right portion of the base of her tongue, where postcontrast T2-weighted Magnetic Resonance Imaging (MRI) evidenced a hyperintense lesion. The fine-needle aspiration specimen taken for cytology was not diagnostic, as a differential diagnosis between myoepithelioma and a malignant neoplasm of the salivary glands necessitates parameters that cytology alone cannot provide. Therefore, the whole lesion was excised by diode laser through a transoral approach. Histology and immunohistochemistry of the completely excised lesion confirmed a myoepithelioma.
