case_images: Buccal changes were accompanied by dryness and pain in the oral cavity (Fig. 1). Biopsy was performed, and pathohistological analysis found a hyperkeratotic epithelium with elongated epidermal extensions and apoptotic keratinocytes, a finding which was consistent with LP (Fig. 1).

case_images: On esophagogastroscopy, circular stenosis in the upper third of the esophagus was found, esophageal lumen being reduced to 1 cm, and its surface covered with pseudomembranaceous layers (Fig. 2). Control endoscopic examination revealed an improvement of mucosal changes, but stenosis is still not passable for endoscope (Fig. 2).
