maxillofacial regions
What does oral and maxillofacial pathology investigate? the causes, processes and effects of these diseases
What does oral and maxillofacial pathology include? research and diagnosis of diseases using clinical, radiographic, microscopic,
biochemical or other examinations, and management of patients
What should you review before diagnosing? -head and neck exam
-normal oral anatomy
-patient history question
-medical history
-social history
What is etiology? origin or cause of diseases
What are the types of etiologies? -reactive
-developmental
-infectious
-neoplastic
What is pathogenesis? Steps in the development of a disease
What is the definition of symptoms? Subjective evidence described by the patient
What is the definition of signs? Objective evidence found during the clinical exam and identified by the clinician
What is the definition of pathognomonic? Describing a symptom or sign that is unique to a particular disease and is
conclusive for a disease/condition
What is a tumor/neoplasm? A new and abnormal growth of tissue that exceeds and is uncoordinated with that
of the normal tissues
Benign tumors end in what suffix? -oma
Malignant tumors are named what? carcinoma or sarcoma
What is hamartoma? Disorganized overgrowth of tissue in its normal location
,What is choristoma? Normal tissue in an abnormal location
What is teratoma? A growth of mature or immature cells/tissues representative of more than one
germ-cell layer or all three layers
What is dysplasia? Abnormal changes in the size, shape, and organization of mature cells
Dysplasia may or may not what? May or may NOT progress to cancer
What does sessile mean? Describing a tumor or growth whose base is the widest part of the lesion
What does pedunculated mean? Tumor or growth whose base is narrower than the widest part of the lesion
What does a pedunculated growth have? a stalk
What does papillary mean? Describing a tumor or growth exhibiting numerous surface projections
What does verrucous mean? Exhibits a rough, warty surface
What does macule mean? Focal area of color change that is not elevated or depressed in relation to its
surroundings
What does plaque mean? Lesion that is slightly elevated and is flat on its surface
What may plaque be? May be a different color or texture vs surrounding tissue
Definition of scar? Indicates previous wound healing •
Physical characterisitics of a scar? Paler and often firmer than surrounding tissue
What is a fissure? -Linear cleft/grooves in the epithelium
-Can be normal or abnormal
What is a sinus/sinus tract? Channel from an infected cavity that permits escape of pus
, What is a fistula? Abnormal passage between two body parts
What is a papule? Solid, raised lesion that is less than 5 mm in diameter
What can a papule have/look like? -may have a "stalk" (pedunculated) or broad base (sessile)
-color can vary
What is a nodule? Solid, raised lesion that is more than 5 mm in diameter
What is the upper limit of a nodule? The upper limit of a nodule ranges from 1 cm - 3cm
What is a pustule? Blister with purulent exudate (pus)
What is a vesicle? Small, fluid-filled "blister"
What are the characteristics of a vesicle? -Can be single or multiple
-May coalesce
-<5mm in diameter
What is a bulla and its size? -Fluid-filled "blisters"
-> 5mm (0.5cm)
What is erosion? -Superficial lesion •
-Arises secondary to rupture of a vesicle or bulla
What is erosion characterized by? Characterized by partial or total loss of the surface epithelium
What is an ulcer? Loss of the surface epithelium and frequently some of the underlying connective
tissue
What does an ulcer appear as? Appears depressed or excavated and is often painful
What is a cyst? Pathologic epithelium-lined cavity, often filled with liquid or semi-solid contents
What is petechiae? Small, round, pin-point areas of hemorrhage
What is ecchymosis and its size? -Non-elevated area of hemorrhage
-Larger than 2 cm in size
