A “kissing burn” occurs:

A “kissing burn” occurs:



a. At extensor surfaces in electrical exposure when the current causes flexion at a joint, protecting that area but leaving the exposed extensor surfaces at greater risk for damage.

b. At flexor surfaces in electrical exposure when the current causes flexion at a joint, and the moisture in the flexor crease leads to an arc burn and extensive deep tissue damage.

c. When a child “sucks” an electrical outlet.

d. When a child bites an electric cord.

e. When lightning “kisses” the skin, leaving a typical fernlike pattern.

The answer is b. A peculiar type of burn associated with electrical injury is the kissing burn, which occurs at the flexor creases. As the current causes flexion of the extremity, the skin of the flexor surfaces at the joints touches. Combined with the moist environment that often occurs at the flexor areas, the electric current may arc across the flexor crease, causing arc burns on both flexor surfaces and extensive underlying tissue damage.
