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 21-years-old male patient who presented with a painless firm fluctuant swelling in right 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. MRI scan was done for confirmation. Superficial parotidectomy procedure was done, taking care not to injure the divisions of the facial nerve with submental flap reconstruction. 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.
