[Cryotherapy of the cylindroma syndrome].

Two patients with dermal Cylindromas were successfully treated with a special cryoapplicator. This small cryosurgical unit consists of a copper core of 645 g with a 1,5 cm insulating styropore body. At the one end, the cylindrical core has a projection bearing the therapeutic surface, at the other a thread, which takes up a manipulator. This serves the purpose of transfering the core into liquid gas and, after throughout cooling, into the styropore body. After half an hour of therapeutic use, the warmed core requires new cooling in liquid nitrogen or liquid air.
