We describe an interesting case of a man with recurrent cutaneous and hematologic manifestations of vitamin B12 deficiency. In this deficiency, the skin, central nervous system, blood, and blood-forming tissues are commonly involved. We describe an overview of vitamin B12 deficiency and the successful treatment of a patient's ongoing cutaneous hyperpigmentation.
