Surgery for Stable Vitiligo: When Can White Patches Be Treated Surgically?

What is vitiligo?

Vitiligo causes white patches where the skin’s pigment cells (melanocytes) have stopped working or been lost. It is not infectious, not caused by food, and not a sign of poor health, though it can run in families and sometimes occurs with thyroid or other autoimmune conditions. In India, where the contrast with brown skin is marked, vitiligo can deeply affect confidence, and many people seek treatment.

Most people start with medical treatment: creams, light therapy (phototherapy) and sometimes tablets. Surgery is considered when patches are stable but have not responded enough.

Why does stability matter so much?

Surgery moves healthy pigment cells into a white patch. If vitiligo is still active, the moved cells may be lost again, and the cut on the donor skin can trigger a new white patch there. Indian guidelines therefore recommend surgery only for stable vitiligo, usually meaning:

• no enlargement of existing patches for a defined period, often about a year;
• no new patches during that time;
• no new patches appearing at sites of minor injury or friction;
• sometimes a small test graft that takes well before larger treatment.

Which types respond well?

Type	Response to surgery
Segmental vitiligo (one side or one area)	Often good, as it tends to stabilise early
Small stable patches on face, neck, trunk	Good
Stable patches on arms and legs	Moderate to good
Fingertips, knuckles, lips, nipples, genitals	Harder; less predictable
Widespread, active vitiligo	Not suitable until stable

What are the surgical options?

Technique	How it works	Suits
Punch (mini) grafting	Tiny plugs of normal skin set into the white patch	Small patches, lips
Suction blister grafting	Blister roof of normal skin placed on the prepared patch	Small to medium patches, good colour match
Thin split-skin grafting	Very thin sheet of skin laid on the patch	Larger, flat areas
Non-cultured melanocyte transplant	Pigment cells separated from a small skin sample and spread on the patch	Larger areas from a small donor site

The white patch is first prepared by gently removing its surface layer, then the graft or cell suspension is applied and dressed. Most procedures are done under local anaesthesia as a day case. Dr. Sushrut routinely performs melanocyte transplants for suitable patients.

Recovery and what to expect

Time	What happens
First week	Dressing kept on; the treated area must not be rubbed or moved much
1 to 2 weeks	Dressing removed; donor site healing
4 to 8 weeks	Pigment dots start to appear in the patch
3 to 6 months	Colour spreads; light therapy may be advised
6 to 12 months	Final colour judged

Colour may be slightly darker or lighter than the surrounding skin at first and often evens out over months.

Risks to discuss

Uneven or patchy colour, a cobblestone texture with punch grafts, colour mismatch, infection, donor site marks, failure of the graft to take, and new patches at the donor site if vitiligo is not truly stable.

Myths about vitiligo

• “Vitiligo is contagious.” It is not.
• “Eating certain foods causes it.” There is no good evidence for this.
• “Surgery cures vitiligo forever.” It treats stable patches; the condition itself can still appear elsewhere.
• “Any patch can be operated on.” Stability and site decide suitability.

When should you see a doctor?

See a dermatologist early for new white patches, to confirm the diagnosis and start medical treatment. Consider a surgical opinion when patches have stayed stable but have not repigmented enough with medical treatment.

What to ask

• Is my vitiligo stable, and how do you judge that?
• Which technique suits my patch and its site?
• Should a test graft be done first?
• What treatment will I need afterwards?
