British supermodel Naomi Campbell spent a second day recuperating in a Brazilian hospital Wednesday after doctors removed a cyst.

"We have been instructed to not release any information regarding Naomi," a Sirio Libanes Hospital spokeswoman said on condition of anonymity in line with hospital policy. "All I can tell you is that she is still at the hospital and that she is recovering very nicely."

Neither the spokeswoman nor Campbell's publicist, Jeff Raymond, knew how long she would remain there.

Campbell, a frequent visitor to Brazil who earlier this month celebrated Carnival in the northeastern city of Salvador, was admitted in recent days to the Sao Paulo facility.

Gynecologist Jose Aristodemo Pinotti described the procedure as a laparoscopy, in which doctors use a thin, lighted scope to view internal organs.

On Tuesday, the day after the surgery, Pinotti said Campbell was "completely cured and walking in her room."

The supermodel also was being cared for by David Uip, one of Brazil's leading experts in the treatment of infectious diseases, the hospital said.
