Pathology and Microbiology
Koilonychia is a nail abnormality characterized by thin, brittle, and spoon-shaped nails. It is frequently observed in chronic iron deficiency secondary to malnutrition, chronic blood loss, or malabsorption. It may also be idiopathic or related to occupation and rare systemic disorders. Presence of koilonychia should prompt investigations for iron deficiency.
