Signs of leucoderma

  • There are clear cut visual signs of leucoderma.
  • Loss of skin pigmentation occurs in leucoderma giving rise to white patches on skin.
  • These patches of loss of pigmentation are flat and even in level with rest of the dermis.
  • There is normally no scale formation in the lesion areas.
  • These white patches prominently occur on the extremities like hands and feet.
  • Initially in leucoderma, the loss of pigmentation occurs as small spots and it progresses to cover larger areas with different shapes.
  • The loss of pigmentation initially appears to be connected to the parts of the body exposed more to sun.
  • These areas of loss of skin pigmentation are prominent on the face, feet, wrists and hands.
  • Another tel-tale sign of this disease of white patches is depigmentation around the orifices of the body like mouth, nostrils, eyes, ears, genitalia, anus and umbilicus.
  • vitiligo

  • In some cases these white patches with loss of pigmentation show hyperpigmentation on the margin of the lesions.
  • The hair growing on the lesion area also loses pigment and turns grey.
  • In the vitiligo affected there is premature graying or whitening of hair on the head, eye brows, eyelashes or beard.
  • In dark skinned people the inside of the mouth may also loses colour.
  • Leucoderma is more noticeable in dark skinned people.
  • Exposure to sun makes the lesions more noticeable and can cause sun burn.
