Early data also support reduced non-melanoma and melanoma skin cancer risk in patients with vitiligo. Post-pubescent vitiligo has been associated with greater acrofacial disease and thyroid disease. Childhood vitiligo has been associated with an atopic diathesis, halo nevi, and family history of vitiligo and autoimmunity.

Most studies demonstrate slightly greater prevalence and earlier onset in females. The prevalence of vitiligo ranges from 0.4 to 2.0% with regions of greater or lesser prevalence.

The cornerstone of management is halting progression and preventing further spread.

Repigmentation is often slow and incomplete.

It can occur at any age, affects both sexes equally, and can be psychologically devastating.

Vitiligo is not an infectious condition.

Vitiligo is a disorder of pigmentation manifesting as white macules and patches.

Spontaneous repigmentation can occur, but response to treatment is slow. Psychosocial support is a cornerstone of management, as vitiligo can have devastating psychological effects for the patient and family. The precise etiology remains controversial, but proposed hypotheses include a host attack on normal melanocytes and intrinsic melanocyte defects in genetically-predisposed individuals. The distribution can be either localized or widespread and often favors sites of frequent friction or trauma. Vitiligo is an acquired skin condition characterized by sharply-demarcated depigmented macules and patches which is typically chronic in nature.
