oral swellings Flashcards
what are the various disease processes that can cause tumours/enlargements in the mouth
Foci of granulation tissue and infection Benign and malignant neoplasms Salivary glands Cyst Abscess Mucous extravasation and retention in minor
GNSCAM
common oral swellings/enlargements on the lips and buccal mucosa
- fibroepithelial polup
- denture hyperplasia
- mucocele
- connective tissue tumours
- salivary tumour
- squamous cell carcinoma
what is denture hyperplasia
reactive lesion due to excessive and chronic mechanical pressure on vestibular oral mucosa (ill fitting denture). may be inflammatory in nature due to poor denture hygiene, ill fitting denture
What is the most common site for a mucocele
lower lip
what causes a mucocele
usually local trauma, causing rupture of salivary duct and mucin spills into surrounding soft tissues
most of salivary gland tumours occur in the
parotid gland (pleomorphic adenoma, warthin tumour)
second most common site for salivary gland tumours is
minor salivary glands (relatively high proportion are malignant, 40% pleomorphic adenoma)
where in the oral cavity do minor salivary gland tumours most commonly occur
palate (post hard palate, soft palate have greatest concentration of glands)
etiological factors for scc
tobacco smoking, alcohol, iron deficiency, radiation, immunosuppression, candidal infection
common oral swellings/enlargements on the gingiva
- periodontal abscess
- fibrous epulis
- pyogenic granuloma
- giant cell epulis
- peripheral ossifying fibroma
- gingival cyst
- peripheral odontogenic cyst
- SCC
what is pyogenic granuloma
exuberant tissue response to local irritation eg gingival irritation and inflammation from poor OH
characteristically ulcerated
children, young adults, pregnant women
where does peripheral ossifying fibroma occur
exclusively on the gingiva
gingival cyst has a predilection for which teeth
mandibular canine and premolar
enlargements at the palate could be
abscess (lateral incisors, palatal root of molar)
torus
salivary gland tumour (post palate)
where can pyogenic granuloma occur
gingiva, tongue
enlargements on the oral floor and ventral tongue
mucocele/ranula
lymphoid aggregates
lymphoepithelial cyst
scc
what is a lymphoepithelial cyst
oral lyphoid tissue epithelium invaginates into tonsillar tissue to form tonsillar crypt filled with keratin.
<1cm diameted
yellow/white
overlying mucosa smooth, non ulcerated
enlargements in the bone
torus, fibrous dysplasia, exostosis, odontogenic cyst/tumour, osteoma, osteosarcoma
fibrous dysplasia vs osseous dysplasia
osseous dysplasia usually does not cause expansion; normal bone replaced by abnormal bone
fibrous dysplasia bone replaced by excessive proliferation of cellular fibrous connective tissue, expansile mass
osteoma usually at
body of mandible (posterior to premolars on lingual surface)
blue-purple enlargements
kaposi sarcoma hemangioma hematoma mucocele giant cell epulis
prognosis of mucosal melanoma vs cutaneous melanoma
mucosal melanoma usually present at more advanced stage, more aggressive
yellowish enlargements
lipoma
granular cell tumour
enlargements that are firm and movable
granuloma
connective tissue neoplasm
adenoma
enlargements that are firm and fixed
granular cell tumour
fibromatosis
indurated and fixed lesions in the oral cavity
SCC BCC salivary adenocarcinoma sarcoma lymphoma melanoma
bony hard lesions in the oral cavity
osteoma
fibro osseous lesions
odontogenic cyst
