Soft tissue lesions Flashcards
list developmental oral cyst of newborn
and management
(congenital)
Keratin: bohn nodules, epstein pearls, dental lamina cyst
blood: eruption cyst
management: clinical diagnosis and leave alone cept eruption cyst
location and origin of Bohn nodules
junction of hard and soft palate or on vestibular region (rare)
origin epithelial remnants of minor salivary glands
location and origin of epstein pearls
mid palate raphae
origin epithelium entrapment between palatal shelves
location and origin of dental lamina cysts
crest of alveolar ridge
odontogenic origin from cell rest of serres
appearance, location and origin of eruption cyst
soft, fluctuant sessile, dome shaped, translucent bluish colour
alveolar ridge
soft tissue variant of dentigerous cyst, from separation of reduced enamel epithelium from crown of tooth
treatment: naturally marsupializes as tooth erupts, symptomatic treatment of simple removal of roof of cyst (trauma and pressure causes discomfort)
what is ankyloglossia and effects
developmental: abnormally short anteriorly positioned lingual frenum that may result in restricted movement
effects: breast feeding difficulties, restriction of tongue movement
gingival recession in severe cases, speech and malocclusion
treatment for ankyloglossia
congenital
if breast feeding problems (<1month) frenotomy/frenolotomy (cut), frenectomy (tissue removed and more advanced surgical techniques)
internvene when: gingival stripping, recession, fremitus, tongue mobility with functional impairment (speech: sibilant sounds), diastema after perm canine eruption (mixed dentition)
poorly supported: malocclusion
vascular anomalities: tumours vs anomalities
congenital
tumours: endothelial proliferation (growth)
appears 1-3 months and high rate proliferates then involutes, F>M
malformations: structural problems, present at birth and only grows with child’s age, does not involute, (trauma, puberty, pregnancy can accelerate growth), no gender predilection
vascular tumour: infantile hemangioma
prevalence, characteristics and diagnosis and management
early infancy 1-3 months, F>M, predilection for head and neck region
clinical presentation: rapid growth and proliferation, benign, self limiting involution over time, may cause complications
management: depending on location
if in eyes/bone/tongue/brain/crucial areas will have compressive issues
different from congenital hemangioma clinically and histologically
vascular malformation classification and examples, syndromes
low flow: capillary, venous, lymphatic (lymphangioma)
high flow: ateriovenous malformation (arteries join to vein wo capillary, expansion of venous base)
combined
no gender predilection
sturge-weber (capillary)
lymphangioma
definition
prevalence
clinical presentation
def: bilated malformed lymphatic channels or cysts of varying size
prev: 50% at brith, 90% diagnosed by 2
pres: microcytic form, tongue most common, buccal mucosa second most, intraosseous (cystic hygromahard to take out)
congenital epulis definition prevalence clinical presentation histology (congenital)
congenital granular cell tumour
pre: 0.0006% of newborns, 8-10 more common in females
pres: single, firm, smooth, sessile or pedunculated round mucosal coloured mass <2cm around anterior maxillary alveolar ridge
management: diagnosis clinical and histological
granular cell tumour with no display of strong reactivity to S100 protein
surgical excision, recurrence unlikely
primary herpetic gingivostomatitis
presentation and management
majority subclinical incubation 5-7 days prodrome 1-2 days vesiculation and ulceration symptoms reduce from 6th day resolves in 10-14 days around
mxn: symptoomatic care, anti-pyretic analgesic, fluids, 0.2% chlorhex, acyclovir within 72hr of infection for immunocompromised
reactivation of HSV
appears on keratinised tissue only: attached gingiva, vermillion border of lips
HPV types and management
6/11 most common
16/18 cause scc/cervical cancer
orals: squamous papilloma, verruca vulgaris, condyloma acuminatum (assoc sexual abuse), heck’s disease (Focal Epithelial Hyperplasia, is an asymptomatic, benign, precancerous? neoplastic condition characterized by multiple white to pinkish papules)
mxn: excisional biopsy except for heck disease
