FOH: Oral Pathology Flashcards
Distinguished by a color change. Flat. (e.g. freckles)
Macule
Small circumscribed lesion. Less than 1 cm in diameter. Elevated.
Papule
Palpable solid lesion. Up to 1 cm in diameter in soft tissue. Can occur above/level/beneath mucosal surfaces.
Nodule
Solid, raised mass larger than 1 cm in diameter and has depth. Neoplastic cells.
Tumor
Outwardly growing lesion.
Exophytic
Stem-like or stalk base similar to a mushroom.
PEDUNCULATED!!!!!!!
Lesion with wide base that is flat or broad.
Sessile
Small nipple-shaped projection. Found in clusters (e.g. HPV)
Papillary
Small, fluid filled sacs. Less than 1 cm in diameter (e.g. THE HERP).
Vesicle
Circumscribed elevated lesion. More than 1 cm in diameter. Contains serous fluid. Blister-like. Caused by immunological disease
Bulla
Variously-sized circumscribed elevations that contain pus.
Pustule
Loss of surface tissue due to sloughing of necrotic inflammatory tissue.
Ulcer
Non-healing ulcer. Chronic.
Erosion
Narrow slit or cleft. May be caused by an impeding denture.
Fissure
Area with a flat surface and raised edges (e.g. leukoplakia).
Plaque
Little red spots, ranging in size from pinpoints to several mms. Caused by escape of small amount of blood.
Petechia
Large reddish-blue areas caused by escape of blood (bruise). Does not blanch on diascopy.
Ecchymosis
Formation of capillaries near surface of tissue (look like red pimples). Sign of hereditary disorder, alcohol abuse, or malignancy in the region. Simple touch may cause bleeding.
Telangiectasia
How would you describe the consistency of necrotic tissue upon palpation?
Cheesy
Consistency of tori?
Hard
A wave-like motion that is felt when a fluid-containining structure is palpated.
Fluctuant
Lesion that has elasticity.
Rubbery
Fixed; closely compressed; compact lesion.
Firm
An excessive hardening or firmness. Referring to oral cancer.
Indurated
Reddish color. Inflammatory or immune related.
Erythematous
Collections of ectopic sebaceous glands. Usually found in buccal mucosa, usually asymptotic. Diagnosis made clinically (no biopsy).
Fordyce Granules
- Variation of normal
Exophytic nodular growth of dense cortical bone located in the midline of the hard palate.
Torus Palatinus
(If on the mandible it is Torus Mandibularis)
- variation of normal
Normal finding of melanin containing cells in the gingival tissues of non-caucasians.
Physiological Melanin Pigmentation
- variation of normal
Prominent, dilated, lingual veins on the ventral and lateral surface of the tongue. Asymptomatic, bilateral symmetry.
Lingual Variscosities
- variation of normal
Accumulation of fluid within epithelial cells of buccal mucosa. Grayish or white lesion. Differentiate from other white lesions by stretching (it will disappear).
Leukoedema
- Variation of normal
Benign conditions of unknown origin:
- Fissured tongue
- Geographic tongue
- Hairy tongue
A rare condition in which the filiform papillae become elongated.
Hairy tongue
Multiple, irregularly shaped erythematous patches with white rims.
Geographic tongue
Rare. Grooves or depressions on the tongue.
Fissured tongue
