cryanesthesia (s) (noun), cryanesthesias (pl)
1. The inability to perceive cold: Yvonne always carried an extra pair of mittens during the winter months because she always suffered from cryanesthesia and was never sure if she were actually cold.
2. Loss of the perception of cold, as during hypothermia or from the application of certain freezing compounds: By the time Sally, the lost hiker, was found, she was suffering from cryanesthesia and required medical attention.

A condition of cryanesthesia may also involve the intentional application of cold, such as with liquid nitrogen, to produce anesthesia for a short term operation, as with the lancing of a boil, removal of a nevus (a mole or birthmark), cosmetic "sandpapering" of the skin, etc.
