Vitiligo is a chronic depigmentary disorder characterized by loss of skin pigmentation due to melanocyte destruction or dysfunction.
Vitiligo represents a multisystem concern requiring integrated treatment approaches.
Epidemiology and Clinical Significance
Vitiligo demonstrates distinct epidemiological patterns across different demographic groups and geographic regions.
- Factor 1: Autoimmune destruction of melanocytes
- Factor 2: Genetic predisposition
- Factor 3: Environmental triggers (oxidative stress, infection)
- Factor 4: Neural factors and neurotransmitter abnormalities
- Factor 5: Often associated with thyroid disease and other autoimmune conditions
Causes and Risk Factors
Understanding the molecular and cellular mechanisms underlying Vitiligo guides precision therapeutics.
- Well-demarcated depigmented macules and patches
- Often symmetric distribution
- Common on face, neck, hands, genitals
- Koebner phenomenon possible
- Often spreads gradually; course unpredictable
Pathophysiology and Disease Mechanisms
The pathophysiology of Vitiligo involves multiple interconnected biological pathways.
- Segmental: rapid initial spread, early onset, often unilateral
- Generalized (non-segmental): slow progressive, later onset, often symmetric
- Focal: limited to single area
- Acrofacial: affects face and distal extremities
Symptoms and Clinical Presentation
Symptom progression in Vitiligo correlates with underlying pathophysiological changes.
- Topical corticosteroids
- Topical calcineurin inhibitors
- Phototherapy (narrowband UVB, PUVA, excimer laser)
- JAK inhibitors (ruxolitinib) - emerging therapy
- Depigmentation (monobenzone) for extensive disease
- Surgical options (skin grafting, melanocyte transplantation)
- Cosmetic camouflage
