A mum has died after injecting Vaseline into her breasts to make them bigger.
Amateur athlete Sonia Perez Llanzon, 39, suffered a fatal blood clot in her lung a month after being admitted to hospital with breathing problems following the dangerous procedure.
Julio Pla, Head of Surgery at Lucio Molas Hospital in Santa Rosa, 350 miles south west of Buenos Aires, said: "The dead woman arrived at hospital with injuries to her breasts.
"She denied everything at first but then confessed she had injected Vaseline into them.
"I've never seen a case like this. The human body has antibodies to remove bacteria and viruses but it hasn't got any mechanisms against this type of product.
"Other people using Vaseline like this are putting themselves in danger."
Sonia's police cadet son Kevin Berazategui, 20, wrote on his Facebook page: "I will love you for ever. The 20 years I spent by your side were beautiful."
Local media reported Sonia was 'obsessed with her appearance' and that she had suffered third degree burns last year while sunbathing.
Doctors have warned in the past about increasing numbers of men injecting themselves with Vaseline, which contains petroleum, to increase the size of their penises. Injuries consists of severe deformations caused by tissue damage and erectile dysfunction.
