white spot
Light-colored fleck
White spot refers to any pale or unpigmented area on a surface, often indicating disease, damage, or abnormality.
In fishkeeping, white spot (or ich) is a parasitic infection causing small white dots on fish: The goldfish has white spot—we need to treat the tank.
On fingernails, white spots usually result from minor trauma.
The term appears across fields from dermatology to plant pathology, always describing localized loss of normal coloration.
