Tongue carcinoma in Plummer-Vinson syndrome: a modern rarity.

Plummer-Vinson syndrome (PVS), formerly known as Paterson-Brown-Kelly syndrome or sideropenic dysphagia, is a sporadic condition defined by the typical triad of symptoms, which are iron deficiency anaemia, oesophageal strictures and dysphagia. PVS predominantly affects women between the ages of 40 and 70. PVS, if left untreated or undiagnosed, may be associated with an increased risk of developing squamous cell carcinoma of the upper gastrointestinal tract or oral cavity, even in the absence of other risk factors. This case study describes a woman who is in her 50s who developed carcinoma of the tongue as a result of chronic dysphagia and untreated iron deficiency anaemia. This article emphasises the need for dental surgeons to be aware of the oral aspects of anaemia and be able to detect PVS to aid in early diagnosis and treatment.
