ABSTRACT

Congenital onychodysplasia of the index fingers (COIF) is a rare disorder characterized by various forms of nail dysplasia which are mainly limited to the index fingers. The aetiology of the disease is still a matter of debate. COIF is characterized by five criteria congenital occurrence, unilateral or bilateral index finger involvement, variability of nail appearance, possible hereditary involvement, and frequently associated bone abnormalities. We report a case of COIF, which is associated with Dandy-Walker variant.
