Question Answer
what are the 3 basic “clinical categories” (this won’t make sense probably until you see this at least once- wording awkward)1) Clinical diagnosis evident & tx may or may not be needed (e.g. Aphthous ulcer, geographic tongue, lichen planus reticular type) 2) Clinical diagnosis evident: tx necessary (e.g. Traumatic ulcer, abscess/infec, symptomatic lichen planus) 3) Clinical diagnosis UNCERTAIN: diagnostic procedure necessary (This includes taking a biopsy, xrays, etc)
when seeking to understand or explain the underlying cause of a disease state or set of symptoms you are concerned with the _______ (term)Etiology
the mechanism and course that results in clinical signs and symptoms is the disease or condition’s _______ (term)Pathogenesis
What is the gold standard of diagnostic procedures (also the most common)Surgical Biopsy
what are three types of surgical biopsy?Shave, punch (incisional), excisional
what type of surgical biopsy is done when lesion is diffuse, multifocal, or the dx is uncertain (precancerous or cancerous?, etc)Punch/Incisional (does not completely remove, is diagnostic and not curative)
what type of surgical biopsy is done when lesion is localized and benign; more curative = removes lesion completelyExcisional biopsy
what are 3 sites of normally Keratinized tissue of mouthgingiva, palate, and dorsum of tongue
t/f: filiform and fungiform papilla are on the ventral surface of the tonguefalse (end on lateral borders of tongue… so not on ventral surface)
memorize

clinical descriptive terms

Question Answer
flat spot, no topographic changes; due to change in pigmentation, overproduction of melaninMacule
rough, elevated and irregular in the surface (Oral leukoplakia is often seen on ventral surface of tongue)Plaque
< 1cm lesion with no change in texture, only change in subsurface structureNodule (BV, fat, lymph nodes, etc could all cause this)
> 1cm lesion with no change in texture, only change in subsurface structureMass (if on side of neck think Lymphoma)
lesion that is discontinuity of surface mucosa, patch of surface epithelium is lost (due to trauma, chemicals, etc)Ulcer
lesion like a mucocele, fluid-filled with Serous fluidVesicle
lesion like a mucocele, pus-filledPustule
tissues peeling away filled w/ fibrotic tissue (seen in pemphigoid and some drug use)Desquamative
pinpoint vesicle with no pusPapule
hemorrhagic spotsPetechiae
large, bruise-like lesionsEcchymosis
pathologic cavity that is lined by epithelium and contains fluid or semisolid material (keratin, mucus or cellular debris)Cyst
memorize

histologic descriptive terms

Question Answer
extra layers of keratin on the epithelium, gives it white colorHyperkeratosis
epithelium is breaking down, losing attachment to one another; seen in PemphigusAcantholysis
