Rescate con rituximab en paciente con liquen plano esofágico refractario

Esophageal lichen planus (ELP) is a rare condition with unknown prevalence that can sometimes be underestimated due to the subtle and nonspecific findings of diagnostic workup. Oral lesions rarely extend to the esophageal mucosa, but when they do, the most frequent symptoms are dysphagia and odynophagia. There is often a significant delay in diagnosis and inadequate treatment. We report the case of a 59-year-old woman diagnosed with ELP, successfully treated with rituximab, a chimeric monoclonal antibody that depletes CD20+B cells. To our knowledge, this is only the second report of this treatment in ELP.
