A man in his 60s presented with a six month history of fingernail discoloration. The patient had a 10 year history of hypertension and diabetes. He had been diagnosed with chronic renal failure five years previously and had been receiving regular haemodialysis for end stage renal disease for the past three years. His fingernails showed white proximal nail beds with no lunula and a distal pink transverse arcuate band (fig 1). The toenails were unaffected. Fungal examination of the nail fragments was negative.
