Glossitis of the tongue in iron deficiency anemia has been described as diffuse or patchy atrophy with tenderness or burning. One cause of iron deficiency anemia is sideropenic dysphagia (Plummer–Vinson or Paterson–Brown–Kelly syndrome) which is also characterized by esophageal webbing and dysphagia. Pernicious anemia is usually caused by autoimmune destruction of gastric parietal cells. Parietal cells secrete intrinsic factor which is required for the absorption of vitamin B12. Vitamin B12 deficiency results in megaloblastic anemia and may present as glossitis. The appearance of the tongue in vitamin B12 deficiency is described as "beefy" or "fiery red and sore".

Body part as an object than IO pantomimes (despite the prevailing conception that they are simpler), and that BPO involves the right hemisphere as well as the left hemisphere. These results could be extended as an explanation of why apraxic brain damage - usually found in left-hemisphere - leads to BPO production. This may be an indication that apraxic’s utilize their right-hemisphere in lieu of their left-hemisphere damage, and therefore produce more BPO pantomimes. Concepts leading to the exploration and discovery of body part as object pantomimes first began in the late 19th century. Problems in the ability to comprehend or communicate with symbols, asymbolia,
