Skin examination
Attention
- Consider who is the most culturally appropriate person to perform a skin examination — based on preference, gender, kinship
- Only do full examination when necessary — in many cases a targeted examination is best
What you do
Ask about (OLD CARTS)
O nset — slow or sudden, associated with injury or event, food or drug use
L ocation — where is it
D uration — how long has it been there, had it before, changing over time
C haracteristics — itchy, bleeding, painful, red, swollen, crawling sensation
A ggravating factors — what makes it worse (eg worse when touched)
R elief — what helps
T ried — what have they already tried, what worked before
S igns and symptoms (other) — done anything lately that’s different, travel, contact
with people with a rash, recent weight loss/gain, joint pain, feeling unwell, fever,
cough, eating and drinking (what and how much), medicines used
Do full head-to-toe exam
- Ask person to undress, leave underwear on
- Don’t forget to look inside mouth and at soles of feet
- Ask about lesions on scalp, areas covered by underwear. Check with consent
Look and check for
- Overall condition and colour of skin
- Condition of hair and nails
- Any differences in colour or appearance of arms, legs, hands, feet. Compare sides
- Hydration — skin turgor. Lightly pinch loose piece of skin
- Does skin return to normal straight away or stay pinched
- Any swelling or redness
- Oedema — legs, feet, hands, bottom, face. Does pressing leave a dent (pitting)
- Sores, lumps or rashes
- Burns, scars or bruises
- Blanching — press skin with piece of glass (eg slide) or acrylic (eg clear plastic ruler) and note if rash fades
Bleeding into skin appears as red-purple blotches/spots that don't blanch under pressure — note if lesions are raised. Pinpoint lesions are petechiae, larger lesions are purpura
Swollen nodes
- Look at neck for lumps, swelling, any obvious pulsating
- Palpate (feel) head and neck with both hands. Take care with the elderly, infant’s fontanelle — especially if less than 18 months
- Start at tip of chin, feel around under jaw to below ears, then feel down muscles at each side of neck to end of collarbone — Figure 7.1
- Gently feel behind ears for enlarged nodes, move along to nape of neck, gently follow muscle line down to shoulders
- Also feel axillae (armpits) and groin
Figure 7.1
Feel skin temperature — hot, sweaty, cold, clammy
Rash or lesion
- Colour — red, purple, pale, multi-coloured, blanching or not
- Size of lesions, distribution over body
- Any of
- Acanthosis nigricans — dark, velvety discoloration in folds of skin usually in the back of the neck, armpit, groin. May indicate insulin resistance — Figure 7.2
- Atrophy — loss of thickness of epidermis, dermis, other tissue
- Blister/vesicle — skin bleb filled with fluid
- Crust — dried serum, thick mass of skin scales, or both
- Cyst — deep fluid-filled cavity
- Erosion — partial loss of epithelium or mucous membrane
- Erythema — redness
- Excoriation — scratch marks scoring epidermis
- Fissure — crack or split in epidermis
- Lichenification — thickening of skin surface, looks like leather
- Macule — flat spot. Can see but can’t feel it
- Nodule — lump deeply set in skin
- Papule — small, dome-shaped, may be skin coloured
- Plaque — raised solid flat spot, usually larger than 1cm
- Pustule — skin bleb filled with pus
- Scale — flaky
- Ulcer — total loss of skin or mucous membrane

Lump or mass
- Location — involves skin, muscle, tendon, bone
- Movement — easy/hard to move, loose, fixed to surrounding structures
- Size — draw around edge with pen, then measure
- Shape — regular/irregular, a/symmetrical (un/even), defined/diffuse edges
- Shade — dark, light, variegated (multi-coloured), different colours
- Signs of inflammation — red, painful, pus, crusting, dry, moist
- Surface edge and consistency — looks different to skin around it
- Feel — hard, soft, smooth, rough, fluctuant (like liquid) in boil/cyst
When assessing for melanoma — look for
- A symmetry — uneven
- B order — irregular
- C olour — uneven
- D iameter — more than 5mm
- E volving — changing size and colour
Do
- Measure and describe clearly in file notes
- Take digital photo (with consent) with paper measuring tape, ruler, or paper with measurements beside
- Keep a copy with file notes, email to specialist for further advice
