Cystadenoma of the mandible: a rare presentation

To our knowledge this is only the second reported case of a cystadenoma that arose in the mandible. These are rare benign epithelial neoplasms of the salivary gland that comprise 0.8%-6.3% of all minor tumours of the salivary gland. Because cystadenoma of the mandible is so rare, there is little evidence or guidance about management, and enucleation remains the recommended treatment. Careful histological diagnosis is important for differentiation from other morphologically similar salivary gland tumours such as a mucoepidermoid carcinoma.
