Lip, Oral Cavity and Oropharynx
ICD-O-3 topography code: C00-C06, C09-C10, C14
ICD10: C00-C06, C09-C10, C14
           

A carcinoma arising in a pre-existing pleomorphic adenoma. It most often occurs in the parotid gland and less often in the submandibular gland and minor salivary glands. Patients usually present with a history of a long-standing mass which recently had undergone rapid growth. The prognosis depends on the invasiveness of the malignant component. Patients with non-invasive or minimally invasive tumors usually have a good prognosis following surgical resection. Invasive tumors are usually aggressive and are associated with recurrences and metastases.
