[Granular cell (Abrikosov) tumors treated with CO2 laser]

The authors are dealing with the CO2-laser as a new treatment possibility of granular cell tumors. Since years they have not seen recurrences. Because of the painless postoperative period, the quick recovery and good functional results CO2-laser surgery seems to be the treatment of choice in these cases.
