Copper Deficiency Myeloneuropathy in Autoimmune Disease.

Copper deficiency is a rare and potentially treatable cause of myeloneuropathy. The most common causes of acquired copper deficiency include malabsorption following gastric surgery and excessive zinc supplementation. Clinical manifestations can be localized to the dorsal spinal cord and present similarly to those that characterize classic vitamin B12 deficiency. In this report, we present the case of a 76-year-old female with copper deficiency myeloneuropathy as a presumed consequence of advanced systemic sclerosis (SSc).
