The benign myoepithelioma is a rare tumor of the salivary glands. It is low grade and represents approximately 1% of the total benign lesions. Description: We present the case of a 48-year-old patient who visited the Otorhinolaryngology office for presenting a right parotid tumor. In fine needle aspiration, positivity is obtained for high-grade cystic adenoid carcinoma. Later in the histological study after the suprafacial parotidectomy, the lesion of benign myoepithelioma is diagnosed. Discussion: Fine needle aspiration for the cytological study is not very sensitive in these types of tumors, being able to give false positives and negatives, which make the myoepithelioma present a diagnostic security in the FNA around 75%. Why histological studies are needed when we observe how in the myoepithelioma a behavior similar to mixed tumor occurs, with absence of ductal structures and the existence of chromosomal alterations in 12q. Conclusions: The benign myoepithelioma can be confused by epi-myoepithelial carcinoma or with malignant myoepithelioma, presenting similarities with the latter.
