A 61-year-old woman presented with a 6-month history of a persistent burning sensation on her tongue (Figure 1A). The patient was not taking any medications and had not been exposed to any new foods or oral hygiene products at the time her symptoms began. Our clinical diagnosis was glossitis. A cytologic evaluation did not show evidence of Candida species. Laboratory investigations to rule out underlying hematologic diseases showed macrocytic anemia and low levels of vitamin B12 (83 [normal 200–700] pg/mL), consistent with vitamin B12 deficiency anemia. The patient was referred to her primary care physician for further management of the condition. She received a single injection (1000 μg) of vitamin B12, which resulted in complete resolution of her symptoms and the normal clinical appearance of her tongue after 3 days (Figure 1B). The cause of the patient’s condition and her need for long-term supplementation remain under investigation.

(A) Generalized dryness of the tongue of a 61-year-old woman with vitamin B12 deficiency, with atrophy (blue arrowheads) and erythematous plaques (white arrowheads). (B) Normal appearance of the tongue 3 days after the patient received a single injection of vitamin B12.

Vitamin B12 deficiency anemia most commonly results from malabsorption syndrome (primarily because of a lack of intrinsic factor) or inadequate consumption of the vitamin.1 Older people and people with a vegetarian diet are at the highest risk for this form of anemia; up to 20% of older adults have been reported to have the condition.1,2 The initial clinical presentation of vitamin B12 deficiency anemia often includes nonspecific symptoms such as fatigue, weakness, paresthesias and vertigo.2

Glossitis is present in up to 25% of cases,3 initially presenting as inflammatory changes characterized by bright red plaques; it may then evolve into the atrophic form, noted as atrophy of the lingual papillae, affecting more than 50% of the tongue’s surface.3 Reported oral symptoms include a burning sensation, pruritus, lingual paresthesia, glossodynia and dysgeusia.3 Treatment is usually lifelong intramuscular or oral administration of vitamin B12.3
