intro and description Flashcards
what does an OMP do
studies the causes of diseases, mechanisms which produce them, sites where they occur, and the resulting morphologic and functional alterations
clinical differential dx
list of possible dx for oral lesion based on what pt tells you that will determine the next step in pt management
why make a decision tree
encourages the clinician to make a series of step by step decisions and consider a number of different lesions when formulating a differential dx
t/f. surface lesions of oral mucosa do not exceed 2-3 mm
true
3 categories of surface lesions
white, pigmented, red
2 categories of soft tissue enlargements
reactive and tumor
a tumor is a…
neoplasm
tumors show…
persistent and progressive growth
t/f. in a decision tree, a tumor is based on microscopic features, not clinical behavior
FALSE, based on clincial behavior
features of reactive soft tissue enlargements
usually regress sometimes painful rapid growth fluctuate in size associated with tender lymphadenopathy
3 types of tumors
benign, cysts, malignant
features of tumors
persistent and progressive
asymptomatic (early)
varying growth rate (weeks to years)
determine benign or malignant
features of benign tumors
slow growing
normal mucosa
freely movable
asymptomatic
4 categories of benign tumors
epithelial
mesenchymal
salivary gland
soft tissue cysts
features of malignant tumors
rapidly growing
ulcerated mucosa
fixed to surrounding structures
symptomatic
t/f. elementary lesions are morphologic alterations
true.
elementary lesion that is flat change in color, <1cm
macule
elementary lesion that is a flat change in color, >1cm
patch
elementary lesion that is solid, slightly raised, flat, or bumpy
plaque
elementary lesion that is removable plaque
pseudomembrane
elementary lesion that is a solid raised lesion, <1cm
papule
elementary lesion that is a solid raised lesion, >1cm
nodule
elementary lesion is a solid raised lesion >5cm
tumor
elementary lesion that is raised, fluid filled <1cm
vesicle
elementary lesion that is raised, fluid filled, >1cm
bulla
elementary lesion with partial loss of epithelium
erosion
elementary lesion with complete loss of epithelium
ulcer
how do you describe oral lesions?
A - anatomic location B - border C - color, consistency, config D - diameter/dimension E - elementary lesion
how do you describe the borders of a lesion
limits/definition, ir/regular contour
