CNN said the beauty queen, who was crowned Miss Argentina in 1994, died Sunday in a hospital after she underwent elective surgery on her buttocks at a clinic last Wednesday.
Authorities said they are investigating the circumstances of her death.
Cosmetic surgery is big business in Argentina where international tourists flock to undergo cheaper procedures by experienced physicians. An estimated 1 in 30 Argentines have had plastic surgery, CNN noted.
