| Question | Answer |
|---|---|
| Little white or reddish ulcer | aphtha |
| outer scab like layer of solid matter formed by drying of a body exudate or secretion | crust |
| closed, epithelial-lined sac, normal or pathologic, that contains fluid or other material | cyst |
| outermost and nonvascular layers of skin | epidermis |
| the dermis or true skin just beneath the epidermis | corium |
| soft tissue slightly depressed lesion in which the epithelium above the basal layer is denuded | erosion |
| read area of variable size and shape; reaction to irritation, radiation, or injury | erythema |
| growing outward | exophytic |
| benign bony growth projecting from surface of bone | exostosis |
| narrow slit or cleft in epidermis where infected ulceration, inflammation, and pain can result | fissure |
| unknown etiology | idiopathic |
| hardened; abnormally hard | indurated |
| use of finger and thumb of same hand | bidigital |
| use of a single finger | digital |
| use of finger or fingers and thumb from each hand applied simultaneously in coordination | bimanual |
| the two hands are used at same time to examine corresponding structures on opposite sides of body | bilateral |
| lesion limited to small focal area | localized |
| involves most of area or segment | generalized |
| one lesion of particular type with distinct margin | single lesion |
| more than one lesion of a particular type | multiple lesions |
| discrete, not running together; may be arranged in clusters | separate |
| close to each other with margins that merge | coalescing |
| lesion above the plane of skin or mucosa, considered blisterform or nonblisterform | elevated lesion |
| lesion that contains fluid, usually soft and translucent | blisterform |
| blisterform lesion, small 1cm or less, this surface covering, may contain serum or mucin & appear white | vesicle |
| blisterform lesion, may be more or less than 5mm in diameter, contains pus that gives yellowish color | pustule |
| blisterform lesion, large/more than 1cm, filled with fluid, usually mucin or serum, may contain blood | bulla |
| lesion that is solid and does not contain fluid | nonblisterform |
| nonblisterform lesion, small/pinhead to 5mm in diameter, solid and may be pointed, rounded, or flat topped | papule |
| nonblisterform lesion, larger than papule (greater than 5mm but less than 1cm) | nodule |
| nonblisterform lesion, 2cm or greater in width, general swelling or enlargement, does not refer to neoplasm, either benign or malignant | tumor |
| nonblisterform lesion, slightly raised with broad, flat top, usually larger than 5mm in diameter, "pasted on" appearance | plaque |
| lesion below level of skin or mucosa | depressed lesion |
| most depressed lesion, represent loss of continuity of epithelium, center is often gray to yellow, surrounded by red border, may result from rupture of elevated lesion | ulcer |
| shallow, depressed lesion, does not extend through epithelium to underlying tissue | erosion |
| lesion that is on same level as normal skin or oral mucosa, may occur as single or multiple lesions | flat lesion |
| circumscribed area not elevated above surrounding skin or mucosa, may be identified by color, which contrasts with surrounding normal tissues | macule |
| resembles small, nipple shaped projection or elevation | papillary |
| loose membranous layer of exudate containing organisms, precipitated fibrin, necrotic cells, and inflammatory cells produced during inflammatory reaction o surface of tissue | pseudomembrane |
| any mass of tissue that projects outward or upward from normal surface skin | polyp |
| marked with points or dots differentiated from surrounding surface by color, elevation or texture | punctate |
| bony elevation or prominence usually found on midline of hard palate | torus |
| rough, wart-like | verrucous |
