Mucoepidermoid carcinoma (MEC) is the most common malignant neoplasm of the major salivary glands, accounting for 15.5% of all cases, benign and malignant. The aim of this article is to report a case of MEC in a 73-years-old male patient who presented with a painless firm fluctuant swelling in left preauricular area. The lesion was thoroughly examined preoperatively, and investigations were carried out. Fine-needle aspiration cytology was done for the lesion and report suggested tumor of the parotid gland. Superficial parotidectomy procedure was done, taking care not to injure the lower division of the facial nerve. Post recovery was uneventful with no defect of facial nerve functions. The histologic picture confirmed that the tumor was MEC of parotid gland. Through the literature reviews of MEC the discussions on prevalence, origin, diagnosis, histological finding, investigation and the modes of treatment are made.
