Close-up of a red, swollen tongue in anaemia. The condition of the tongue is affected in a number of blood disorders. Mild anaemias or deficiencies of iron, folate or vitamin B12 may result in a sore & inflamed tongue or mouth. The smooth appearance of this tongue is due to a loss of papillae (the projections associated with the taste buds). In addition, the cracked, inflamed appearance of the corners of the mouth are typical of a blood disorder.
