An Oregon woman made headlines earlier this year when she yanked a worm from her inflamed eye, National Geographic reported.
The good news is that he worm is easy to remove and does not case lasting health problems.
Over five days, a 32-year-old woman in Russian Federation took selfies to document a odd lump on her face that moved from under her left eye to above it and then later to her lip. As this worm remains typically infertile inside the human beings, the solution to these types of cases is generally removing the worm by a surgery.
The woman documented the different lumps she had been witnessing by taking selfies in order to keep a track of the roving blemishes. According to the New England Journal of Medicine, which published the report, the woman recalled being bitten by mosquitoes while on the trip.
A physical exam found a lump that had moved from his arm to the back of his hand, which turned out to be - you guessed it - a massive worm crawling around under his skin.
Her first picture shows it just below her left eye, but five days later the worm had crawled to above her eye.
According to guidelines from the European Society of Dirofilariosis and Angiostrongylosis (ESDA), Dirofilaria repens infections typically appear in humans near the eyes - "eyelids and under the conjunctiva (in such a case the worm can be easily observed, sometimes actively moving), subcutaneous tissues (nodules) in the chest wall, upper and lower limb, neck and in other body regions" such as the genitals.
Dirofilaria are usually found in dogs or other carnivores, according to the CDC, but have been known to infect humans, too, especially in Europe and with certain species - D. repens, D. tenuis and D. immitis (better known as heartworm in dogs). The worms are transmitted by mosquito bites, and can accidentally use a human as a host.
His research showed that between June 1997 and June 2013, almost 1,300 cases of dirofilariasis were found in Russian Federation and Belarus, usually among women who visited rural areas-which is how the unnamed woman in this case study is thought to have contracted the infection. It was "fixed with forceps" and removed surgically.
It is not the first case like this reported in Europe.
It is unclear where the woman picked up the worm, but she did report having been in a town outside of Moscow, where she was frequently bitten by mosquitoes. Mosquitoes serve as vectors for this parasite.
