The most dramatic symptom of<unk>  is that the skin turns blue or blue-grey. It may take the form of generalized<unk>  or local<unk> . Generalized<unk>  affects large areas over much of the visible surface of the body. Local<unk>  shows in limited regions of the body, such as patches of skin, parts of the mucous membrane or the conjunctiva. The terms<unk>  and argyrosis have long been used interchangeably, with<unk>  being used more frequently.
