Lichen planus esophagitis: report of three patients treated with oral tacrolimus or intraesophageal corticosteroid injections or both.

Clinically significant involvement of the esophagus is uncommon in patients who have lichen planus, a common disorder of squamous epithelium. In three patients who had oral, cutaneous, and esophageal lichen planus, endoscopic intralesional esophageal injection of corticosteroids (in all three patients) and oral tacrolimus (FH506) (in two patients) resulted in improvement in dysphagia, a less frequent need for dilation, and improvement in esophageal inflammation.
