Spoon-shaped concave nail - signs of symptoms and causes

2021-03-16 12:00 AM

Spoon-shaped concave nails are associated with soft bed and nail substrate, but this development is not clearly explained. There is little evidence that a spoon-shaped concave nail is a marker in iron-deficiency anaemia.

Causes

Common

Soft nails due to occupational influences.
