Parotid gland mucoepidermoid carcinoma in a 4-year-old child.

Salivary gland tumors account for less than 5% of the head and neck neoplasms. Among them, mucoepidermoid carcinoma is the most common malignant salivary gland tumor. About 45% of mucoepidermoid carcinomas occur in the parotid gland, and appear around the fifth decade of life, being unusual in children under 10 years. We report a case of a parotid mass arising in a 4-year-old female, who had no lateral adenopathy. After histological examination, the diagnosis was of a low-grade mucoepidermoid carcinoma of the parotid gland. Three years after surgery no recurrence was observed. As a conclusion, although rare, the presence of a parotid mass with progressive growth in children could correspond to a neoplasm.
