Synopsis
Recognise inflammation, pallor, cyanosis, jaundice and pigment change across skin tones by combining colour with palpation, symptoms and appropriate anatomical sites.
- Erythema may be bright red, violaceous, grey-brown or mainly visible as swelling, warmth and surface change in deeply pigmented skin.
- Assess pallor at conjunctivae, oral mucosa, palms and nail beds, and interpret it beside symptoms and haemoglobin rather than colour impression alone.
- Look for central cyanosis at tongue and oral mucosa while checking oxygenation; peripheral nail colour is altered by temperature, perfusion, polish and pigmentation.
- Describe hyperpigmentation and hypopigmentation relative to the patient’s baseline, with distribution and texture, rather than using racial categories as proxies.
- For Examining skin of different pigmentation, describe what is seen before assigning a diagnosis, and record site, extent, symptoms, duration and change over time.
- A technically adequate result in Examining skin of different pigmentation can still be misleading when the wrong lesion, site, preparation or clinical question was selected.
Key red flags
Do not dismiss systemic illness because erythema, cyanosis, pallor or jaundice is subtle; abnormal physiology and rapidly evolving pain or purpura override uncertain colour.
Blue or grey tongue and oral mucosa with breathlessness, low oxygen saturation or altered consciousness requires immediate physiological assessment.
Diffuse darkening involving creases, scars and oral mucosa with weakness, weight loss or postural symptoms suggests adrenal disease.
Investigation priorities
Identify colour, temperature, texture and elevation relative to baseline.
Management branches
The patient is stable and the result will alter diagnosis, referral or follow-up.
- Define the question for Examining skin of different pigmentation, explain the process and obtain valid consent before exposing, touching, photographing or sampling skin.
- Choose representative anatomy, optimise lighting or specimen technique, and document site, morphology, symptoms and relevant previous treatment. Apply that step specifically within the examining skin of different pigmentation assessment and its recorded clinical context.
- Interpret the result beside the full clinical pattern, communicate uncertainty and arrange ownership of results and safety-netting. Apply that step specifically within the examining skin of different pigmentation assessment and its recorded clinical context.
