Oral Pathology Flashcards
What causes a cleft lip?
- lack of fusion between medial nasal process and maxillary process
What causes a cleft palate?
- lack of fusion between palatal shelves
Clefts + pits = ??
Van der Woude Syndrome
- white or whitish-gray edematous lesion of buccal mucosa
- dissipates when cheek is stretched
Leukoedema
White annular (ringed) lesions surrounding central red islands that migrate over time
Geographic tongue AKA benign migratory glossitis
Folds and furrows of tongue dorsum
fissured tongue
Fissured tongue + granulomatous cheilitis + facial paralysis = ??
Melkersson- Rosenthal Syndrome
- Mels bells = facial paralysis
- Rosy Red = granulomatous cheilitis
Congenital focal proliferation of capillaries
hemangioma
congenital focal proliferation of lymph vessels
- lymphangioma
- very rare
- when on neck it is called cystic hygroma
Angiomas of leptomeninges (arachnoid and pia mater) + skin along the distribution of trigeminal nerve = ??
Sturge-Weber syndrome
- mass in midline floor of mouth
- doughy consistency
dermoid cyst
- lateral neck swelling
- epithelial cyst within lymph node of neck
branchial cyst
- epithelial cyst within lymphoid tissue of oral mucosa
- palatine and lingual tonsils are common
oral lymphoepithelial cyst
- radiolucency in posterior mandible BELOW mandibular canal
- due to lingual concavity of the jaw
Stafne Bone Defect
- Heart-shaped radiolucency in nasopalatine canal
Nasopalatine duct cyst
- Term denoting any radiolucency between maxillary canine and lateral incisor
Globulomaxillary lesion
- Large radiolucency SCALLOPED AROUND ROOTS
- no epithelial lining
- usually associated with jaw trauma
Traumatic Bone Cyst
- red dots, inflamed salivary duct openings
nicotine stomatitis
- brown, diffuse, irregular macules
- typically seen in anterior gingiva
smoking-associated melanosis
- benign hyperpigmentation in mucous membrane
- basically a freckle of mucosa
Melanotic macule
freckles + intestinal polyps = ??
Peutz-Jeghers Syndrome
(PJs - Freckles - intestinal distress)
elongated filiform papillae
Hairy Tongue
