Spooning of the nails and webbing of the esophagus: koilonychia and Plummer–Vinson Syndrome

Chronic iron deficiency can be associated with nail deformities like Koilonychia and Platynychia. It can also be associated with esophageal webs (Plummer‐Vinson syndrome or Patterson‐Brown‐Kelly syndrome) causing dysphagia in the patient. Though the pathogenesis of this association remains anecdotal and presence of these physical findings should prompt the clinician towards considering chronic iron deficiency as the cause of anemia.
