Man and tapeworms

Is it coincidence that the BBC should have two stories about tapeworms and men? The first story tells about a man who died from tumors made of cancerous parasitic worm tissue growing in his organs, i.e. the tissue was not human. The patient had HIV and his weakened immune system allowed the worm-cancer to flourish. The dwarf tapeworm spends most of his time hatching eggs into the gut every day.

The second story tells of a larva of a tapeworm inside a man's brain. The doctor pulled it out and it was still wiggling. This condition is called neurocysticercosis; it affects about 1,000 people a year.
