Skin Color Changes due to Inflammation

Inflammation can cause skin color changes, either darkening (hyperpigmentation) or lightening (hypopigmentation).

Rash Configurations

Rashes can appear in different patterns, like straight lines (linear), circles (annular), clusters (grouped), or in areas of previous skin damage (Koebner phenomenon).

Rash Morphology

Rashes can be flat, raised, or sunken in the skin, and have various textures like soft, firm, hard, or even feeling like you can move fluid around (fluctuating) or very stiff (sclerosed).

Rash Classification

A rash is considered uniform throughout (monomorphic) or with many different appearances (pleomorphic), indicating varying stages or forms.

Clinical Skin Examination

A careful skin exam involves observing the patient's skin, understanding their needs, and respecting their dignity. During the exam, note the skin's appearance, temperature, moisture, texture, and any color variations.

Skin Turgor

Skin turgor measures how quickly the skin returns to its original position after being pinched. Reduced turgor can be a sign of dehydration or certain medical conditions.

Skin Color Variations

Pallor is a pale skin color that can indicate anemia or poor circulation. Cyanosis is a bluish tint to the skin that may indicate low oxygen levels. Erythema is redness of the skin, often caused by inflammation or infection. Jaundice is a yellowish discoloration of the skin, often a sign of liver problems. Hyperpigmentation is increased skin pigmentation, while hypopigmentation is a loss of skin pigmentation.

Study Notes

  • Darker skin may show hyperpigmentation or hypopigmentation due to inflammation.
  • Rash configurations include linear, annular (circular), grouped, and the Koebner phenomenon (e.g., psoriasis after local trauma).
  • Rash morphology varies: can be flat, elevated, or depressed, with soft, firm, hard, fluctuating, or sclerosed textures.
  • Rashes can be classified as monomorphic (uniform) or pleomorphic (varying stages or forms).

Differential Diagnosis of Fever with Rash

  • Maculopapular Rash: Includes discrete flat macules and tiny raised papules; can blanch on pressure. Associated with infections like measles, rubella, scarlet fever, and Lyme disease.
  • Diffuse Erythroderma: Characterized by thickened scaly skin; may indicate severe conditions like toxic shock syndrome or Kawasaki syndrome.
  • Urticarial Rash ("Hives"): Pink, raised, and itchy lesions due to infections, food/drug reactions, or environmental factors.
  • Vesicular, Pustular, Bullous Rash: Involves raised lesions containing clear or purulent fluid; linked to bacterial infections or severe conditions like Stevens-Johnson syndrome.

Chickenpox and Shingles

  • Chickenpox progression: Spots transform into blisters, then scabs; manage symptoms with hydration and cooling treatments.
  • Treatment includes antihistamines, paracetamol, and cooling creams; avoid ibuprofen and aspirin in children under 16.
  • Shingles symptoms include tingling/pain followed by a unilateral rash; it involves itching blisters that crust over.
  • Shingles can be severe for immunocompromised individuals and requires antiviral treatment if initiated within 72 hours.

Skin Examination Principles

  • Clinical skin examination emphasizes observation, consent, and respecting patient dignity.
  • Assess skin's appearance, temperature, moisture, texture, and any variations in color.
  • Important to identify changes in turgor as a sign of dehydration or medical conditions.
  • History taking should include onset, location, associated symptoms, and any treatments attempted.

Taking a Skin History

  • Ask about changes in rash appearance, symptoms accompanying the rash, and previous medications.
  • SOCRATES framework helps guide history questions regarding onset, location, and exacerbating or relieving factors.

Important Skin Examination Considerations

  • Initial assessment begins upon entering the room; watch how the patient walks.
  • Keep adequate lighting and privacy during examination; use visual inspection, palpation, and sense of smell.
  • Document the skin's dimensions, symmetry, tenderness, and consistency.

Variations and Signs of Skin Conditions

  • Conditions that cause color changes can include pallor, cyanosis, erythema, jaundice, hyperpigmentation, and hypopigmentation.
  • Skin temperature can be an indicator of systemic issues; note localized warmth or coolness and their causes.
  • Skin texture should be closely assessed for any deviations from the patient’s normal.

Common Skin Conditions Observed in Practice

  • Be vigilant for new or changing rashes, allergic reactions, infections, and wounds.
  • Confirm any recent exposures or contacts that may relate to the current skin status.
  • Evaluate the rash's distribution, timing, and any associated symptoms, like itchiness or pain.
