Tumors of the Salivary Glands

Benign Tumors

Most of the salivary gland tumors are benign and occur in the parotid glands with the most common being a pleomorphic adenoma (mixed tumor).  If the tumors turns malignant, even with good surgery and therapy, there are highly low cure rates. Other benign tumors are monomorphic adenoma, oncocytoma, and papillary cystadenoma lymphomatosum. These are the tumors that rarely become malignant.

Symptoms:

Most of these tumors are painless. However, because they would invade nerves, there can be a level of numbness, causalgia, or a loss of motor function.

Diagnosis:

  • Fine-needle aspiration biopsy
  • CT and MRI for extent of disease
