Description

The absence of pigment producing cells from the epidermis causes the acquired pigmentary skin condition known as vitiligo, which manifests as white macules and patches all over the body. Thyroid problems are the most frequent autoimmune illness connected with the syndrome. There are numerous theories to explain the pathogenesis of vitiligo, despite the fact that its etiology is unknown. Clinically, vitiligo manifests as symmetrically distributed white spots on the body part which are more noticeable in those with dark skin. Well defined pearly white or depigmented macules and patches that are oval, circular, or linear in shape with convex borders that can range in size from a few millimetres to centimetres and expand centrifugally are the hallmarks of the lesions.

Etiology

It is unclear which causes vitiligo specifically. It frequently occurs in conjunction with certain autoimmune disorders. Its pathophysiology is the subject of numerous theories, and its etiology is complex. Many susceptibility loci, genetic variability, and imperfect penetrance are its defining traits. Studies on families and twins have demonstrated that inheritance is complicated and involves both genetic and environmental influences. The age at which vitiligo first appears may also be influenced by genetic factors, according to another theory. Inheritance of vitiligo may also include genes involved in the control of autoantibodies, melanin production, and oxidative stress response.

Epidermology

The most frequent reason for depigmentation is vitiligo. Although it can manifest at any age, from childhood to maturity, the second and third decades are reported to have the highest occurrence. The age of onset often varies by gender. It affects all races equally and has a prevalence of 0.1% to 2% among all persons, including adults and children globally.

Pathophysiology

Multifactorial polygenic condition that is vitiligo has a complicated pathophysiology. It is frequently linked to both hereditary and non-genetic variables. Nonetheless, a number of hypotheses regarding its pathogenesis have been put forth, but the precise etiology is still unknown. The melanocytes in vitiligo skin are absent, and their loss is caused by their destruction, according to commonly accepted concepts. Progressive melanocyte reductions are the most common effect of the destruction. Cytotoxic mechanisms, autoimmune mechanisms, intrinsic melanocyte abnormalities, neurological mechanisms, and oxidant antioxidant mechanisms are some of the theories regarding melanocyte death.

Depigmentation therapies

When more than 50% of the body's surface is affected by vitiligo, or if aesthetically sensitive areas are the main factor, these remedies are typically advised. For the first month, Monobenzyl Ether of Hydroquinone (MBEH) 10% is used topically daily. The following month, MBEH 20% is applied topically twice daily. If the areas are not responsive and are tolerated, the concentration can be increased to 30-40%. Patients typically show depigmentation in locations far from the application after three to six months. Cryotherapy, laser therapy, 88% phenol solution, and 4-methoxyphenol are further treatment possibilities.

CONCLUSION

Every single treatment modality has a different therapeutic impact on different people. As a result, treatment needs to be customised. In general, patients who are younger, have recently developed the condition, have darker skin tones, and have head and neck lesions have the best therapeutic response. For patients with limited disease, topical corticosteroids and calcineurin inhibitors are the preferred treatments. For lesions on the face, neck, intertriginous regions, and genitalia, topical calcineurin inhibitors are typically chosen. Patients with widespread vitiligo or those with localised vitiligo that has a severe impact on quality of life and does not respond to treatment with topical corticosteroids and calcineurin inhibitors should undergo narrowband ultraviolet B phototherapy.
