Oral Patho Flashcards
Differences between:
- epstein pearls
- bohn’s nodules
- dental lamina cyst
- epstein pearl= epi inclusion cyst (keratin-filled) found on median raphe of HARD PALATE
- -small, white, firm - bohn’s nodule= keratin cysts from odontogenic epi or salivary gland remnants or over dental lamina; found on alveolar ridges; max>mand; buccal aspect MC
- dental lamina cyst= remnants of dental lamina; seen on alveolar ridges
- -yellow-white cyst
ALL ARE SELF-LIMITING AND RUPTURE ON ITS OWN IN A FEW WEEKS TO A FEW MONTHS
DDx for whitish/yellowish cyst-like lesion on newborns
depending on where it is:
- epstein pearl–midline raphe of palate
- bohn’s nodule–buccal aspect of alveoli
- dental lamina cyst–alveolar ridge
- natal teeth–mand>max
What is Congenital Epulis of Newborn?
define epulis: benign soft tissue tumor on gingiva
- basically the peds version of epulis fissuratum with older adults with dentures.
- excess gingiva
- F>M
- max>mand
tx: complete excision; low recurrence rate
What is Melanotic Neuroectodermal Tumor of Infancy?
- Malignant tumor consisting of epithelial cells with melanocytic granules.
- MC w/i 1st yr of life
tx: wide and complete resection; HIGH recurrence rate
Which blanch?
Hemangioma vs hematoma
- Hemangiomas will blanch because they are vascular lesions.
- typically they regress on their own. If not, systemic B-blockers can be used
Ddx for port-wine stain?
- vascular malformation
- glaucoma
- Klippel-Trenaunay syndrome
- port-wine stain lesion w/o underlying systemic dz (isolated event)
What percentage of submucosal clefts are associated with bifid uvula?
10%
Large tongue; normal color; deep fissures on dorsal surface.
DDx?
- dry mouth
- Down syndrome
- melkersson-rosenthal syndrome
DDx for white lesions that do not wipe off
- white sponge nevus–bilateral; everywhere; thickened plaque; get at a young age
- leukoedema–disappears when stretched; MC in black ppl
- candida–wipes off
- lichen planus–immune response
- chemical/mucosal burn–toothpaste, electric burn, food, ASA, etch/formo
- contact stomatitis–toothpaste ingredients, etc
Common lip lesions in children
- angular cheilitis–S. aureus or candida; crohn’s dz, anemia, lick lipping, irritation, allergy, immuno-compromised
- HSV 2–vesicular, crusty, comes and go’s
- cold sore
- HFM
- impetigo
- lip licking
- allergic cheilitis
- varicella
Three P’s on gums
Pyogenic Granuloma
Peripheral Ossifying Fibroma
Peripheral Giant Cell Granuloma
Describe pyogenic granuloma
- -MC in preggo pts
- -on or near papilla
- -does not displace teeth
- -can be well vascularized red/purple lesions
Describe Peripheral Ossifying Fibroma
- -may see radiopaque flecks on PA
- -can displace teeth
- -easily removed with LOW recurrence rate
Describe Peripheral Giant Cell Granuloma
- -lucent on PA
- -can displace teeth
- -consider Med Hx bc DDx can be Brown Tumor of Hyperparathyroidism
