In addition to women looking for bargains, the clients for black-market treatments include transsexuals seeking to augment breasts and buttocks with large volumes of silicone, Sergeant Llevat said, procedures the medical establishment considers too dangerous. Also, doctors say some women who can afford legitimate doctors get a thrill from having illicit treatments. "Wealthy women are going to injection parties," said Dr. Daniel Kane, a plastic surgeon in Miami who treats complications from these procedures.
