Dermatology - Vitiligo 
Vitiligo affects 1% of people globally and can have negative social and economic repercussions for people with darker skin. Men and women experience the same chronic illness, however women seek therapy more frequently. Although it can occur at any age, the most common range for onset is 10 to 30 years. uncommonly linked to alopecia areata, pernicious anemia, and thyroid disorders.
Many patients blame illnesses, physical trauma, or psychological stress for the onset. White or prematurely gray hair are possible. In macules of vitiligo, photoaging and solar keratosis may occur.
Sharply marginated, chalk-colored or pale white macules range in diameter from 5 mm to more than 5 cm, and they progressively get bigger as new ones form. Convex margins exist. The three colors of vitiligo—white, light brown, and dark brown—represent various disease phases. In a white macule, pigmentation surrounding a hair follicle indicates restored or persistent pigmentation.
Hypomelanotic macules the size of candy can also be seen. The edge of inflammatory vitiligo is more erythematous and can be itchy. A single site may have one or more macules indicative of focal vitiligo. The more prevalent type of vitiligo, known as generalized vitiligo, is typified by a broad distribution of depigmented macules that are frequently strikingly symmetrical around the mouth, eyes, fingers, elbows, and knees in addition to the low back and genital regions.
The perioral region, distal fingers and toes, lips, nipples, and genitalia are all included in the lip-tip pattern.
Large white patches are the result of confluent vitiligo, while widespread generalized vitiligo—also known as vitriligo universalis—may only leave a few regularly pigmented skin areas. Segmental vitiligo appears in a unilateral pattern, usually does not spread beyond it, and is extremely stable once it does.

Clinical diagnosis is made. Pityriasis alba, versicolor, leprosy, postinflammatory leukoderma, mycosis fungoides, chemical leukoderma, white nevi, hypomelanosis, tuberous sclerosis, Vogt-Koyanagi-Harada syndrome, Waardenburg syndrome, and piebaldism are among the conditions that fall under the differential category.

Vitiligo is unaffected by the treatment of underlying diseases. To protect the depigmented skin, use sunscreen; for people with lighter skin, this is frequently sufficient. Darker skinned people might cover up their skin tone with makeup, dyes, or self-tanning products.
Repigment local macules by applying topical psoralens, glucocorticoids, and UVA therapy.
One may try minigrafting or systemic photochemotherapy for generalized repigmentation. Alternatively, some patients choose to undergo depigmentation with bleaching chemicals, such as 20% hydroquinone monobenzylether.
