Abstract
Myoepithelial carcinoma is a rare neoplasm, representing about 1% of malignant tumours from salivary glands. Diagnosis is based on morphological and inmunohisto- chemical features. Vimentin, S-100 protein and calponin are the most frecuent immuno- histochemical findings. Treatment is based on surgical removal with free margins, and sometimes, neck dissection and postoperative radiotherapy. It has been reported that recurrent pleomorphic adenoma could transform into a myoepithelial carcinoma, but in our report, we present a case with this particular malignant transformation within the first tumor presentation and review of literature.
