Other lesions resulting from a nutritional deficiency

Other vitamin deficiencies may provoke mouth lesions: angular stomatitis of the lips and glossitis from vitamin B2 (riboflavin), niacin (see Pellagra, Chapter 4) or vitamin B6 (pyridoxine) deficiencies.

Iron deficiency may also provoke angular stomatitis (see Anaemia, Chapter 1).

Give the corresponding vitamins at curative doses. Multivitamins are insufficient to treat true vitamin deficiencies.
