excision
Surgical removal
in situ
Confined to the site of origin w/o invasion of neighboring tissues
invasion
Infiltration and active destruction of surrounding tissues
leukoplakia
Clinical term used to identify a white, plaquelike lesion of the oral mucosa that cannot be wiped off or diagnosed as any other disease
malignant
Resistant to treatment; able to metastasize and kill the host describing cancer
metastasis
Transport of neoplastic cells to parts of the body remote from the primary tumor and the establishment of new tumors at those sites

peripheral
Occurring outside of bone
pleomorphic
Occurring in various forms

sarcoma
Malignant tumor of connective tissue
calcifying odontogenic cyst
A nonaggressive cystic lesion lined by odontogenic epithelium with associated ghost cell keratinization
odontoma
An odontogenic tumor composed of mature enamel, dentin, cementum, and pulp tissue. The odontoma is the most common of the odontogenic tumors, and there are two types; compound and complex

A well demarcated sessile or pedunulated lesion that appears to originate from the gingival interdental papilla and is most likely derived from cells of the periodontal ligament

A malignant tumor of striated muscle that grows rapidly and is destructive. It is the most common malignant soft tissue tumor of the head and neck in children.
leiomyoma
A benign tumor of smooth muscle mass that may occur in association w/blood vessels
hemanginoma
A benign prolifereation of capillaries. It's a common vascular lesion considered by many to represent a developmental lesion rather than a tumor because it does not generally exhibit an unlimted growth potential
papilloma
A benign tumor of squamous epithelium that presents as a small, exophytic, pedunculated, or sessile growth. It's often described as a cauliflowerlike in appearance and occurs most often of the soft palate or tongue.

A clinical term used to identify a white, plaque like lesion of the oral mucosa that cannot be wiped off and cannot be diagnosed as any other sisease on a clinical basis
erythoplakia
A clinical term that's used to describe an oral mucosal lesion that appears as a smooth red patch or granular red and velvety patch.
epithelial dysplasia
A tumor that develops from epithelium.. There are three types; 1) tumors derived from squamous epithelium 2) tumors dervied from salivary gland epithelium, and 3) tumors derived from odontogenic epithelium
squamous cell carcinoma
A malignant tumor of squmous epitheilum. It's the most common primary malignancy of the oral cavity and like other malignant tumors can inflitrate adjacent tissues and metastasize to distant sites. Also known as epidermoid carcinoma
verrucous carcinoma
A specific type of squmaous cell carcinoma that appears as a slow growing exophytic tumor with a pebbly white and red surface, usually in the vestibule or buccal mucosa. Often assoicatied with the used of smokeless tobacco
basal cell carcinoma
A malignant skin tumor associated with excessive sun exposure that appears as a nonhealing ulcer with characterisitic rolled borders. It does not occur in the oral cavity.
pleomorphic adenoma
The most common of the benign salivary gland tumors. It's also called benign mixed tumor

An unencapsulated and infiltrating malignant salivary gland tumor composed of a combo of mucous cells intersperesed with squamouslike epithelial cells. Major gland tumors occur most often in the partoid gland. Minor gland tumors occur most commonly on the
ameloblastoma
A benign, slow growing but locally aggressive epithelial odontogenic tumor that may arise in either the maxilla or the mandible. It's an unencapsulated tumor that infiltrates into surrounding tissue and can cause extensive destruction.
calcifying epithelial odontogenic tumor
A benign epithelial odontogenic tumor in which the poliferating cells do not resemble odontogenic epithelium. The tumor is composed of ilands and sheets of polyhedral (multisided) epithelial cells. It's also known as a pindborg tumor.
adenomatoid odontogenic tumor
An encapsulated, benign epithelial odotogenic tumor that has a distinctive age, sex, and site distribution. Seventy percent occur in females under 20 years of age; 70% involve the anterior part of the jaws. May be associated with impactd teeth. Also known
melanocytic nevi
A benign tumor of melanocytes. A pegmented congenital lesion. Can arise on the skin or the oral mucosa. Intraoral consist of tan to brown macules or papules that occur most often on the hard palate.
malignant melanoma
A malignant tumor of melanocytes. Can arise on the skin and mestasize to the oral cavity
osteoma
An asymptomatic benign tumor composed of normal compact bone. Slow growing tumor that appears radiographically as either a sharply defined radiopaque mass within bone or a delineated mass attached to the outer surface of the bone
