Een man met acute, pijnloze zwelling van de hand

A 48-year-old man visited the hand surgery outpatient clinic with acute, painless swelling of the dorsal side of the right hand and fingers. We found erythema and crepitations of the skin. Laboratory tests showed no signs of infection. After X-ray and echography of the hand we made the diagnosis subcutaneous emphysema. It was caused by a microtrauma with high pressure air.
