Esophageal lichen planus: a rare case.

Lichen planus is a rare, idiopathic disease that usually involves the skin and mucosae. Oral lesions occur in two thirds of cases and may occur without skin involvement. Esophageal lichen planus occur more frequently in middle-age women, it is frequently asymptomatic but may cause odynophagia and dysphagia. Esophageal lichen planus has been associated with squamous cell carcinoma. The most effective treatment is systemic corticotherapy, but relapse is expected in 85% with steroid withdrawal. We present the case of esophageal lichen planus in a 50-year-old man.
