Scorpion sting

Scorpion stings are a cutaneous condition caused by the stinging of scorpions, usually resulting in pain, paresthesia, and variable swelling. The anatomical part of the scorpion that delivers the sting is called a "telson".
Most scorpion stings vary from small swelling to medically significant lesions in severity, with only a few able to cause severe allergic, neurotic or necrotic reactions. However, scorpion stings account for approximately 3000 deaths a year worldwide.
Two species of scorpions can inflict stings which result in death of normal healthy humans: the Palestinian deathstalker ("Leiurus quinquestriatus") and the Brazilian yellow scorpion ("Tityus serrulatus"). Antivenom exists for both species' stings.
