Oesophageal lichen planus.

We present a case of lichen planus affecting the oesophagus of an 80-year-old woman. Symptomatically, the lesions manifested themselves as dysphagia requiring repeated oesophageal dilatations. The patient was unable to tolerate several conventional treatments and so pulsed methylprednisolone was given with some beneficial short-term effects. Due to potential for malignant change in lichen planus of the mucous membranes it is important to remember this complication and investigate patients with oesophageal symptoms.
