case_images: Images of patient's tongue taken 1.5 years following oral exposure to toxic cleaning agent.. The oral mucosa appears normal, though there is some evidence of possible geographic tongue. Panels
  1A and
  1D show a slight fissure (arrow). Panel
  1B demonstrates an atrophic patch (arrow) consistent with possible geographic tongue. The circumvallate papillae are intact as demonstrated in
  1C (arrows). The lateral lingual mucosa appears normal (
  1E,
  1F).
