RGD uses the Human Disease Ontology (DO, https://disease-ontology.org/) for disease curation across species. RGD automatically downloads each new release of the ontology on a monthly basis. Some additional terms which are required for RGD's curation purposes but are not currently covered in the official version of DO have been added. As corresponding terms are added to DO, these custom terms are retired and the DO terms substituted in existing annotations and subsequently used for curation.
This is a carcinoma that arises from a pleomorphic adenoma in the salivary glands. It usually originates in the parotid gland. Patients usually present with a history of a long-standing tumor mass which grew rapidly in the past few months. Patients with non-invasive or minimally invasive carcinoma have an excellent prognosis. In cases where there is invasion of the surrounding tissues, the clinical course is aggressive.
