Reversible Hyperpigmentation due to Vitamin B12 Deficiency - Mimicking Addison’s Pigmentation
Vitamin B12 deficiency, which is usually seen in vegetarians, is characterised by cutaneous, gastrointestinal, neurological and haematological manifestations. Cutaneous manifestations include hyperpigmentation, glossitis and hair changes. Hyperpigmentation seen in Vitamin B12 deficiency mimics Addison’s disease. Here, we present a case of a 65-year-old male with vitamin B12 associated hyperpigmentation, which improved with B12 supplementation.
