Leukonychia (or leuconychia), is a medical term for white
discolouration appearing on nails.[2]:658–9 It is derived from
the Greek words leuko (“white”) and onyx (“nail”). The most
common cause is injury to the base of the nail (the matrix)
where the nail is formed.
Other possible reasons for this problem with nail colour can be linked to:
Arsenic poisoning
Lead poisoning
Pneumonia
Heart disease
Kidney failure
