British supermodel Naomi Campbell had been hospitalised in Sao Paulo and was being treated by one of Brazil's top specialists in infectious disease, the hospital's press office said on Tuesday.
Her publicist confirmed she was treated at a hospital and said she had a cyst removed.
Campbell, a frequent visitor to Brazil who earlier this month celebrated Carnival in the northeastern city of Salvador, was hospitalised on Sunday in Sao Paulo's Sirio Libanes Hospital.
"The patient and her advisers have determined that the hospital's medical staff will not issue any formal or informal information on her medical condition," a statement released by the hospital said.
Besides David Uip, the specialist in infectious diseases, Campbell is also under the care of gynecologist Jose Aristodemo Pinotti, the statement said.
"Naomi Campbell was admitted to the hospital ... To have a small cyst removed," Jeff Raymond, the model's publicist, said in a statement. "Following the successful procedure, she is now resting and is looking forward to getting back to work.
