Scurvy: more than historical relevance.

The clinical description of scurvy is well recorded in the history of medicine. Yet, because scurvy is relatively uncommon in industrially developed countries, it is often underdiagnosed, and unnecessary tests are performed. The result of a prolonged deficiency of ascorbic acid, scurvy is classically manifested by perifollicular hemorrhages, corkscrew hairs, large ecchymoses and hemorrhagic gingivitis. Although the disease is considered uncommon in the United States, two populations at greatest risk--the institutionalized elderly and alcoholics--are increasing.
