Introduction: Mucoepidermoid carcinoma represents about 15% of salivary gland tumors. They occur mainly in the parotids (60–70%) but they account for a large fraction of salivary gland tumors in the minor salivary glands. Overall they are the most common form of primary malignant tumor of the salivary glands. Our report exemplifies the need to evaluate swellings of the neck region meticulously as it might not be just an inflammatory swelling but an indication of malignancy. Case report: A 36-year-old male patient was referred to our hospital for evaluation of a swelling in the upper neck which gradually progressed over a span of 3 months. It was painless, firm in consistency, and ovoid in shape. The blood and urine investigations were normal. Fine needle aspiration cytology (FNAC) was performed and the findings were correlated with IHC and the mass was confirmed to be a mucoepidermoid carcinoma. Discussion: Mucoepidermoid carcinomas show variability in their behavior. The prognosis is dependent on the clinical stage, site, grading. Duration before diagnosis ranges from months to years. The cure is possible in low and intermediate grades of tumors. Characteristically, it shows t[11;19][q21;p13] with MET1–MAML2 fusion in other cases it occurred in the parotid gland and palate. This is probably the first case reported to occur in a submandibular gland in a patient in the third decade of his life, with its incidence normally common in the 5th to 6th decade.
