A man has died with tumours inside him which were composed of cancerous tapeworms.
Doctors believe that the man, 41, was able to develop the rare condition because he had HIV which caused him to have a weakened immune system.
The bizarre form of the illness was eventually diagnosed by the US Centers for Disease Control and the UK's Natural History Museum, which have laid out their findings in the New England Journal of Medicine.
The patient, a Colombian, was first seen by doctors in 2013, who found that he had what initially seemed to be normal tumours across his liver, lungs and elsewhere.
