The tumours that often occur in the parotid gland - pleomorphic adenoma, cylindroma and carcinoma - may occur in the submandibular gland, but they are rarer. Only 5-10% of all salivary gland tumours occur in the submandibular gland; 50% of them are malignant (1)
In descending order of frequency of occurrence, the tumours in submandibular glands are - adenoidcystic, mucoepidermoid, malignant then benign pleomorphic adenoma, undifferentiated carcinoma (1)
The physical features are almost identical to those in the parotid - hard, fixed masses beneath the mucosa.
