12. Oral pathology and soft tissue lesions in children Flashcards
What do you look at extra-orally?
– General appearance, do they look well?
– Skull (symmetry), hair, ears, eyes, face
– Lymphadenopathy
- look at growth chart and see what percentile they are in
What do you look at intra-orally?
Soft tissues: – mucosa
– inflammation
– red patches, white patches
– swelling
– ulcers
– spontaneous bleeding
– recession
– fraenal attachment
Periodontal tissues Teeth, occlusion Salivary flow rate
How do you describe the lesion?
- Type of lesion
If they had an ulcer ask was it as small as 5 pence coin, 2 pence, tip of pen lid? - Size
– Measure with a ruler in two dimensions - Shape and symmetry
- Colour and pigmentation of lesion – E.g. red, white, purple, brown, grey
- Surface features
– E.g. Smooth, rough - Distribution over the tissue
– Location; diffuse or demarcated - Findings of palpation
– Superficial, deep, movable, fixed, tender
What is a macule?
Flat, discoloured spot on skin with sharp borders
What is a papule?
Solid elevations without fluid with sharp borders
What is a nodule, tumour?
Palpable, solid, elevated mass.
Nodules have distinct borders.
Tumours extend deep into the dermis.
Wart is a nodule.
Large lipoma is a tumour.
What is a pustule?
Vesicle or bulla filled with purulent fluid
What is a wheal?
Localised area of oedema, often irregular and of variable size and colour
What are the 8 primary lesions?
Macule
Papule
Nodule, tumour
Vesicle
Bulla
Pustule
Wheal
Plaque
What are the 4 secondary lesions?
Originate from a primary lesion
Scale, crust, fissure, ulcer
What is a scale?
Thin or thick flake of skin varying in colour, usually secondary to desquamated, dead epithelium, eg. dandruff
What is a crust?
Dried residue of exudates, eg. residue of impetigo
What is a fissure?
Linear crack in the skin, eg. athlete’s foot
What is an ulcer?
Opening in the skin caused by sloughing of necrotic tissue, extending pass the epidermis.
What is erythema?
Redness due to increased blood flow to blood vessels (vasodilatation) in that area
What is purpura?
Red/purple discolouration due to extravasation of blood into the skin from a blood vessel
What colour is melanin and lipid deposition?
Brown and yellow
How should you document a lesion?
With written description, photograph, measurement
What are 3 examples of lesions in the newborn?
Keratin cysts
Congenital epulis
Natal/neonatal teeth
What are 2 examples of keratin cysts?
Epstein pearls
Bohn’s nodules
What are epstein’s pearls?
Hard, raised small nodules
- arise from epithelial remnants trapped along lines of fusion of embryological processes
- appear in midline of hard palate
What are Bohn’s nodules?
- Odontogenic cyst arising from the dental lamina filled with keratin.
- occur in 80% of infants
- normally disappear spontaneously
Describe a congenital epulis?
Usually firm, pedunculated, pink, smooth, solitary
Present at birth
Where are congenital epulis mostly found?
Arise from the crest of the alveolus in the incisor region
