Frostbite is the occurrence of localized tissue freezing and injury. It results following cold exposure of sufficient magnitude or duration to cause acute tissue damage. Although there are several conditions that predispose to frostbite, all are at risk if subject to sufficient cold exposure. We discuss a case of frostbite presenting with bullae localized to the neck resulting from extreme cold encountered while snowmobiling at night in Minnesota, an entity known by some local practitioners as "polaris vulgaris."
