Blue nails, or more formally azure lunula, are characterized by a blue discoloration of the lunulae, seen in argyria and cases of hepatolenticular degeneration (Wilson's disease), also having been reported in hemoglobin M disease and hereditary acrolabial telangiectases.[1]
In Wilson's disease the blue color involves the lunula (most intense pigmentation) and fades proximally. In argyria, the nail is permanently pigmented a slate-blue color and is most evident in the lunula. Minocycline and Zidovudine can also turn the nail plate blue-gray.[2]
Trivia
In season 6 of House MD in the episode 12 titled Remorse, House diagnoses his patient with Wilson's Disease in absence of Kayser-Fleischer rings by removing the nail polish to note the blue nails.
