Cutaneous involvement manifests with flat violaceous papules, and mucosal manifestations typically manifest with white lacelike lesions, papules, erythematous lesions, and erosions (Fig 2) (2). Esophageal lichen planus has been reported in more than 50% of patients with mucocutaneous lichen planus and is underrecognized and underreported (2).Figure 1. Esophageal lichen planus. There are limited studies of the pathogenesis of esophageal lichen planus, but it appears to be mediated by cytotoxic CD8-positive T cells. Biopsy of affected esophageal tissue shows keratinization with inflammatory cell infiltration of the epithelium with activated T lymphocytes (6).Figure 1.Download as PowerPointOpen in Image Viewer Figure 2. Mucosal manifestations of lichen planus in a 73-year-old woman who presented with solid food dysphagia. (A) Photograph shows white plaquelike lesions on the tongue. (B) Endoscopic image demonstrates erythema and white papules (arrows).Figure 2.Download as PowerPointOpen in Image Viewer Barium esophagography is the most relevant imaging study to evaluate esophageal lichen planus. Imaging features include a smooth small-caliber esophagus with cervical esophageal webs, strictures, and pseudodiverticula (Fig 3) (3,4). Strictures most commonly occur in the proximal esophagus, and their presence correlates with a longer duration of disease (5). Squamous cell carcinoma of the esophagus has been rarely reported in patients with esophageal lichen planus; for this reason, early diagnosis is key.Figure 3. Esophageal lichen planus in a 73-year-old woman (same patient as in Fig 2). Barium esophograms show smooth long stricturing of the entire course of the esophagus with tapered margins (white arrow in A) and esophageal webs (black arrows in A). There are focal weblike strictures in an overall small-caliber lumen of the cervical esophagus (black arrow in B). Overall thin smooth luminal narrowing of the entire course of the esophagus is seen in C.Figure 3.Download as PowerPointOpen in Image Viewer Patients with esophageal lichen planus often present with dysphagia related to the strictures, with reflux-type symptoms, and weight loss. Strictures can be treated with balloon dilation, although this often requires regular repeat treatments (5). Endoscopic findings include superficial white papules, pseudomembranes, webs, and strictures.Disclosures of conflicts of interest.—All authors have disclosed no relevant relationships.AcknowledgmentWe thank Ciléin Kearns, MD, MBChB, for feedback and advice on the medical illustration in Figure 1.All authors have disclosed no relevant relationships.
