- Peripheral ossifying fibroma aka ossifying fibrous epulis
epulis = identical to fibrous epulis, but radiographically shows specs of radiopacity
a. Tx: excision
- Neurofibroma
= benign PNS sheath tumor - 90% of time solitary other 10% neurofibromatosis.
neurofibromatosis = neurofibromas + small cafe au lait spots
McCune-Albright syndrome = polyostotic fibrous dysplasia + large cafe au lait spots
a. Tx: excision of solitary lesions
- Neurofibromatosis
= genetic condition multiple neurofibromas + small café au lait spots on skin only (not to be confused with mccune-albright which has large café-au-lait and is form of polyostotic fibrous dysplasia)
a. Tx: no treatment
- Peutz-jegher syndrome
= autosomal dominant; melanotic macules + GIT polyps
a. Tx: no treatment
- McCune-Albright syndrome
= embryotic mutation causing 1) polyostotic fibrous dysplasia 2) large café-au-lait spot 3) hyperfunctioning endocrine (e.g. hyperparathyroidism)
a. Tx: no treatment
- Drug-induced pigmented lesions
= increased melanin production by melanocytes
a. Tx: do nothing, but can excise for aesthetic reasons
- Smoking associated melanosis
= up-regulated melanin production by melanocytes
a. Tx: do nothing, but can excise for aesthetic reasons
- Lichenoid stomatitis
= Lichenoid Stomatitis – clinically identical to lichen planus (BUT NOT ACTUAL LICHEN PLANUS); caused by medication
a. Tx: stop taking that medication
- Necrotizing sialometaplasia (ulcerative)
= “trauma” induced vasculitis to minor salivary glands causing necrosis of less resilient acini cells and metaplasia of more resilient duct cells
a. The trauma could be: smoking, LA injection/surgery, radiation, alcohol consumption
b. True to its name:
i. Necrotizing necrosis of less resilient acini
ii. Sialo- salivary related i.e. acini and duct cells
iii. Metaplasia metaplasia, instead of necrosis, of more resilient duct cells
c. Tx: biopsy to rule out SSC, syphilis, ANUG; will heal after biopsy
