Vitamin B deficiency alone will not cause the syndrome in the presence of sufficient folate, as the mechanism is loss of B dependent folate recycling, followed by folate deficiency loss of nucleic acid synthesis (specifically thymine), leading to defects in DNA synthesis.

Because the problem there is just as severe, but it is more sinister, because vitamin D deficiency, from a lack of ultraviolet B radiation, is a major problem.

Well known human vitamin deficiencies involve thiamine (beriberi), niacin (pellagra), vitamin C (scurvy), and vitamin D (rickets).

If investigations reveal deficiency states, correction of the deficiency may result in resolution of the ulceration.
