Though an uncommon exposure, it can occur from chronic mercury exposure. One mode of exposure that I have seen is with elemental mercury thermometers that were broken to collect the beads of mercury - for entertainment. This occurred in a child's room and were forgotten. One child presented with personality changes and pink hands and feet. The patient suffered from severe mercury poisoning and acrodynia due to prolonged exposure to the mercury vapor.
Acrodynia or Pink Disease includes:
Irritability, shyness, photophobia, pink discoloration of the hands and feet and polyneuritis.
