Over five days, a 32-year-old woman in Russia took selfies to document a strange lump on her face that moved from under her left eye to above it and then later to her lip. She finally visited a physician who reported a “superficial moving oblong nodule at the left upper eyelid.” Turns out, she had a particular kind of parasitic worm, Dirofilaria repens, living under her skin. From Live Science:
Humans are “accidental” hosts — in other words, not where the worms want to end up — and once a worm gets into a human, it typically can’t reproduce.
The worms are spread by mosquito bites, and human cases have been reported in parts of Europe, Asia and Africa, the 2011 report said. The Russian woman said she had recently traveled to a rural area outside Moscow and was frequently bitten by mosquitoes, according to the new report (in the New England Journal of Medicine)…
The Russian woman had the worm removed and made a full recovery, the report said.
