Bleeds easily, also called pregnancy tumor, after some time they become less vascular and can resemble a fibroma
Definition
Pyogenic granuloma
Term
Red and ulcerated on the gingiva
Definition

Definition
Hairy Leukoplakia
Term
Oral manifestations also occur in measles, infectious mononucleosis, lichen planus, and leukemia
Definition
Hairy Leukoplakia
Term
Chronic irritation, smoking, alcohol. Usually found on buccal mucosa, tongue, floor of mouth. Must do a biopsy to diagnose these conditions
Definition
Premalignant Lesions
Term
Presents as a white patch, hyperkeratosis, mononuclear infiltrates, acanthosis, ++ cellular atypica
Definition
Leukoplakia
Term
red, velvety patch, mononuclear infiltrates, +++ cellular atypia, thus associated with higher risk of malignancy
Definition
Erythroplakia
Term
5% of all malignant tumors. Most common site is on the lip and anterior tongue. Spreads to submandibular nodes then upper jugular nodes.
Definition
Squamous Cell carcinoma
Term
Appears as an irregular, roughened mucosal surface that later grows into a cauliflower like growth with an ulcerated surface. Surface is nodular.
Definition
Squamous Cell carcinoma
Term
Infiltrates underlying ct. Can be well differentiated (keratin, intracellular bridges) or poorly differentiated.
Definition
squamous cell carcinoma
Term
Highly differentiated variant of squamous cell carcinoma affecting 60-70 y/o. Does not metastasize, low cellular atypia. White, warty, fungating, patch with bulbous retes
Definition
Verrcuous Carcinoma
Term
Benign tumor of squamous epithelium on the buccal mucosa, gingiva, lips and tongue; HPV is implicated cause
Definition
Squamous Papilloma
Term
Most common Cyst of oral cavity. Related to necrosis of dental pulp due to infection. Attached to the roots of the tooth buds
Definition
Radicular Cyst
Term
Derived from misplaced tooth buds
Definition
Follicular Cyst
Term
Otogenic Epithelium, usually in the mandible, a locally aggressive tumor with common reoccurrence and rare metastasis.
Definition
Ameloblastoma
Term
Occurs with painless swelling, well defined cysts on XR.
Micro: Central core of stellate reticulum. Destroys bone and adjacent structures so it must be removed
Definition
Ameloblastoma
Term
Necrotizing inflammation in the blood vessels, especially arterioles. May affect lungs and kidney at it may occur as part of a systemic disease but localize to nasal cavity. Destruction of nose and sinuses
Definition
Wegner's Granulomatosis
Term
Ulceration of bacterial infection leads to granulomatous inflammation. Regarded as a extranodal T-cell lympoma that destroys the midline masses in the nasopharynx causing deformities
Definition
Lethal Midline Granuloma
Term
Composed of masses of polygonal cells with fibrous stroma
Definition
Transitional cell carcinoma
Term
A mixture of lymphoid elements with malignant epithelial cells
Definition
Lymphoepithelioma
Term
Most common malignant tumor in the nasalpharynx(china, africa) in male 20's.
Definition
Nasopharyngeal Carcinoma
Term
Genetic association, dietary due to nitrosamine in salted fish. Associated with EBV
Definition
Nasopharyngeal Carcinoma
Term
Anaplastic tumor that is highly malignant, metastasizes first to the lymph nodes, then lungs,pleura, liver. Very radiosensitive
Definition
Nasopharyngeal Carcinoma
Term
Only affects adolescent males, benign tumor that causes nasal obstruction and unexplained nosebleeds without trauma
Definition
Nasopharyngeal Angiofibroma
Term
Grows downward,. Has a risk of turning into squamous cell papilloma, which is different from normal papilloma that grows outwards which wouldn't become malignant
Definition
Inverted Papilloma
Term
Occurs as apart of the inflammatory process in the respiratory tract. Important in children and infants because marked exudation or edema can cause laryngeal obstruction
Definition
Laryngitis
Term
Nodules on the vocal cords. Can be Sessile or predunculated. Common in males, heavy smokers, or singers
Definition
Polyps
Term
Neoplasm of viral origin (HPV 6,11) Malignancy is rare. Finger like projections of fibrous tissue covered by squamous epithelium
Definition
Papillomas
Term
Tumors more common in males, smokers, or those exposed to asbestos.
Definition
Carcinoma of Larynx
Term
Common on vocal cords, epiglottis, or aryepiglottic region. Intrinsic remains inside larynx, extrensic is outside
Definition
Carcinoma of Larynx
Term
Patients develop progresive hoarseness of voice, pain, dysphasia, hemptysis and secondary infection
Definition
Carcinoma of Larynx
Term
