Scurvy in a patient with presumptive oral lichen planus.

Scurvy is a disease caused by vitamin C deficiency. In this study, a patient with scurvy is presented with soreness and ulcerations of the mouth that were previously diagnosed as oral lichen planus. This disease is relatively more common than scurvy in the United States. Physicians should be aware that even in developed countries, soreness of the mouth and ulceration can be seen in patients with scurvy and potentially be misdiagnosed as oral lichen planus.
