Koilonychias, also referred to as spoon nails, is a hereditary nail disorder and a possible sign of hypochromia anemia, particularly iron-deficiency anemia. The term indicates abnormal thin nails that have lost their convexity and have become either flat or concave in shape. They start getting thinner with an outline of lifted ends, just like a spoon shape. This is mainly caused due to the absence of anemia and iron in the body, and hence the disorder is associated with Plummer-Vinson syndrome. Other linked causes to Koilonychia are muscle skinning condition, damaged peripheral flow, universal Lupus hemochromatosis, bad thyroid functioning, Patella Syndrome, erythematosus nail, Hypo plastic pattels, Reynaud’s illness, and also sometimes because of use of soaps and oils excessively.
