White Patches on Hand
Having white patches on the hand can be a sign of a condition called Vitiligo. It is a condition where the skin loses melanin and is characterized by slow, enlarging white spots on the skin. It can occur to both male and females in all races but is most noticeable in patients who have naturally darker skin.
As of yet, there is no cure to Vitiligo. The goal of the condition is to instead slow down the growth of the patches. Some patients are also offered treatments that can help return color to the skin.
Vitiligo may start in the hands but it affects the top part of the hand where the skin is found. Patches on the underside of the hands or on the palms may be caused by a different factor.
Cause and Treatment for White Patches
Vitiligo causes de-pigmentation because the cells that produce melanin no longer work or fail to produce it. The exact reason why this occurs, however, is not known. Some theories as to the cause of Vitiligo include:
- Autoimmune condition
- Skin Damage.
The condition can also occur in relation to cancer and skin malignancies.
There is no treatment that can stop Vitiligo altogether. In some cases, treatment isn’t even necessary as the skin color will return on its own. Fair skinned people can make the condition less noticeable by avoiding sun tanning.
Some commonly used treatments for the condition include:
- Corticosteroid Creams or Ointments. In some cases these help to bring the color back to the skin.
- Immunomodulators. These are applied topically and are also shown to help bring back color to skin.
- Photo-Chemotherapy. This is often done for patients with less than 20% skin involvement.
White Patches on the Palm of Hands
The skin on the palm is normally patchy in color where there are areas that are pinkish and white. The following may cause large white patches that do not respond to pressure.
- Flat Warts
- Allergic reaction
- Skin irritation. This can be due to the use or soaps, body products, or certain detergents.
- Ringworm. These are raised ring shaped bumps on the skin that can be very itchy.
The patches on the underside of the palm may also be a result of extended pressure, like when a person sleeps on their hand. If this is the case, it will go away on its own, usually within a few minutes. This is called blanching.
