The Plummer-Vinson syndrome, also called Paterson-Brown-Kelly syndrome or sideropenic dysphagia is a disorder linked to severe, long-term iron deficiency anemia, which causes swallowing difficulty (dysphagia) due to web-like membranes of tissue growing in the throat (esophageal webs). P-VS sufferers often complain of a burning sensation with the tongue and oral mucosa, and atrophy of lingual papillae produces a smooth, shiny red tongue dorsum. The cause of Plummer-Vinson syndrome is unknown; however, genetic factors and nutritional deficiencies may play a role. Women are at higher risk than men, particularly in middle age. In these patients, esophageal squamous cell carcinoma risk is increased; therefore, it is considered a premalignant process.
Additional recommended knowledge
The disease is named after two Americans, the physician Henry Stanley Plummer, and the surgeon Porter Paisley Vinson. 
Signs and tests
Serial contrasted gastrointestinal radiography or upper gastrointestinal endoscopy may reveal the web in the esophagus. Blood tests show a hypochromic microcytic anemia that is consistent with an iron-deficiency anemia. Biopsy of involved mucosa typically reveals epithelial atrophy (shrinking) and varying amounts of submucosal chronic inflammation. Epithelial atypia or dysplasia may be present.
Treatment is primarily aimed at correcting the iron-deficiency anemia. Patients with Plummer-Vinson syndrome should receive iron supplementation in their diet. This may improve dysphagia and pain. If not, the web can be dilated during upper endoscopy to allow normal swallowing and passage of food.
Patients generally respond well to treatment. Iron supplementation usually resolves the anemia, and corrects the glossodynia (tongue pain).
There is risk of perforation of the esophagus with the use of dilators for treatment. Furthermore it is one of the risk factors for developing squamous cell carcinoma of the oesophagus.
Good nutrition with adequate intake of iron may prevent this disorder.
