ABSTRACT
Hyperpigmentation is a recognized sign of vitamin B12 deficiency that resolves after vitamin repletion. We present the case of a 58-year-old female with neuropsychiatric symptoms who developed progressive darkening of her hands and feet. A diagnosis of vitamin B12 deficiency secondary to pernicious anemia was made and her symptoms and hyperpigmentation resolved following vitamin repletion. Clinicians should consider vitamin B12 deficiency in the differential diagnosis of palmoplantar hyperpigmentation, as early treatment can avert permanent disability in these patients.
