Hello, There may be some confusion between Leukoderma and Leukemia because the names sound similar. Leukoderma, also called vitiligo, causes white patches on the skin due to loss of pigment and is usually limited to the skin. Leukemia is a blood and bone marrow cancer and does not typically cause patchy white skin changes. If you notice skin whitening or other symptoms, it is best to consult a dermatologist or general physician for proper examination, diagnosis, and guidance.
