There are many conditions which can present in this manner. Hand eczema which is dry skin can present with white spots. You can treat it with topical cortisone like Clobex Lotion. Allergic reactions or contact dermatitis can also present as white spots on the hands. If you have been exposed to arsenic that can also present like this. It would be best to see your doctor and get the diagnosis confirmed. Thanks.
how could i have been exposed to arsenic? I do not have dry skin or dermititis
Arsenic can be there in water especially in well water. An examination is important for a diagnosis of dermatitis and so you should see a doctor in person. Thanks.
Follow-up questions, if any, are welcome.
