Cao Gío (Pseudo-Battering in Vietnamese Children)
Cao gío is the Vietnamese folk practice of dermabrasion and can be mistaken for trauma. It is performed (on children and adults) as treatment for various maladies, including fever and headache. The trunk is massaged with hot oil until the skin is warm. Firm downward strokes with the edge of a coin are used to produce linear petechiae or purpura that often overlie bony surfaces. Irregular purpuric lesions and diffuse petechiae are also present. Ca̧o gío is a common practice in the Vietnamese culture and should not be confused with abuse.
