Mucosal lesions in lichen planus (LP) involve mostly mouth and genitals. Extension to oesophagus resulting in stenosis is exceptional (only eight cases have been reported so far). We describe two such cases and recall the clinical findings required to correlate an oesophageal stenosis to LP: age and sex status, associated mucosal LP lesions, location on the upper third of the oesophagus, histological features, flare-up of buccal lesions following dilatation.Systemic steroids are regarded as the best treatment in the case ofoesophageai stenosis due to LP, the efficacy of etretinate is limited, and dilatations should be avoided. Dapsone proved to be efficient in severe erosive buccal LP, and could be considered as a valuable therapeutic alternative.

Although retrospective, our study demonstrates that the occurrence of genital SCC in men treated with PUVA therapy is a very rare event in common dermatological practice.
