Plummer–Vinson syndrome (PVS), also called Paterson–Brown–Kelly syndrome or sideropenic dysphagia, is a rare disease characterized by difficulty in swallowing, iron deficiency anemia, glossitis, cheilosis and esophageal webs. Treatment with iron supplementation and mechanical widening of the esophagus generally provides an excellent outcome. Nowadays, this syndrome has become extremely rare.〔 It generally occurs in postmenopausal women. Its identification and follow-up is considered relevant due to increased risk of squamous cell carcinomas of the esophagus and pharynx.〔 == Presentation == PVS sufferers often complain of a burning sensation with the tongue and oral mucosa, and atrophy of lingual papillae produces a smooth, shiny, red, dorsum of the tongue. Symptoms include: * Dysphagia (difficulty in swallowing) * Pain * Weakness * Odynophagia (painful swallowing) * Atrophic glossitis * Angular stomatitis 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Plummer–Vinson syndrome」の詳細全文を読む スポンサード リンク
