<unk>  is a condition of pain and dusky pink discoloration in the hands and feet most often seen in children chronically exposed to heavy metals, especially mercury. The word<unk>  is derived from the Greek word ακρος, which means end or extremity, and οδυνη, which means pain. As such, it might be (erroneously) used to indicate that a patient has pain in the hands or feet. However,<unk>  is a disease rather than a symptom. The condition is known by various other names including pink disease, hydrargyria, mercurialism, erythredema, erythredema polyneuropathy, Bilderbeck's, Selter's, Swift's and Swift-Feer disease.
