Naomi Campbell was hospitalized in Sao Paulo for the removal of a small cyst, her publicist said.

The 37-year-old British supermodel, a frequent visitor to Brazil who earlier this month celebrated Carnival in the northeastern city of Salvador, was treated at Sirio Libanes Hospital.

"Following the successful procedure, she is now resting and is looking forward to getting back to work. She would like to thank the doctors who have kindly looked after her," her publicist, Jeff Raymond, said in a statement yesterday.

Dr. Jose Aristodemo Pinotti, a gynecologist, told The Associated Press by telephone that Campbell underwent abdominal surgery.

"I cannot reveal what Naomi had, nor how serious her condition was, but I can say I operated on her yesterday, that everything went smoothly and that she is completely cured and walking in her room," Pinotti said.

He described the procedure as a laparoscopy, in which doctors use a thin, lighted scope to view internal organs.

"She came to Brazil to be treated for a condition I am not authorized to reveal," he said. He declined further comment.

The hospital also declined to comment on Campbell's condition, but said she was admitted Sunday night.

Dr. David Uip, one of Brazil's leading experts in the treatment of infectious diseases, was also caring for Campbell, the hospital said.
