Paterson-Kelly syndrome; Sideropenic dysphagia
Plummer-Vinson syndrome is a condition that occurs with long-term (chronic) iron deficiency anemia. People with this condition have difficulty swallowing due to esophageal webs -- small, thin growths of tissue that partially block the food pipe (esophagus).
The cause of Plummer-Vinson syndrome is unknown. Genetic factors and a lack of certain nutrients (nutritional deficiencies) may play a role. It is a rare disorder that is often connected with cancers of the esophagus and throat.
