We present a case of lichen planus affecting the oesophagus of an 80-year-o
ld woman. Symptomatically, the lesions manifested themselves as dysphagia r
equiring repeated oesophageal dilatations. The patient was unable to tolera
te several conventional treatments and so pulsed methylprednisolone was giv
en 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.
