Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland neoplasm. It displays a variety of biological behaviour. It affects both the major and the minor salivary glands. The clinical features and biological behaviour of MEC of the minor salivary gland has not been very widely documented. Low grade MEC usually demonstratres a benign nature. Here, we report a case of bilateral soft tissue swellings of the labial mucosa which presented as mucous retention cysts and later diagnosed histopathologically as low grade MEC of the minor salivary gland.
