Mosquito-borne parasite, Dirofilaria repens, found migrating in woman’s face

The worm was surgically removed using special forceps and the woman made a full recovery.

The lump transformed into a weird medical case when it started to move around the woman's face.

Dr. Vladimir Kartashev at the Rostov State Medical University in Russian Federation explained that the women had initially witnessed a nodule under the left eye, which moved up to the top of the left eye within just five days. After 10 days, it moved to her top lip, causing some seriously intense swelling.

She chose to visit an ophthalmologist who confirmed the shocking diagnosis - there was a mobile parasitic worm moving around under her skin.

In a series of selfies, the woman tracked the mysterious lump as it moved across her face.

The woman first noticed the lump under her left eye. According to the New England Journal of Medicine, which published the report, the woman recalled being bitten by mosquitoes while on the trip.

During a surgery to remove the lump, doctors discovered the lump was actually a long, white worm that had been crawling around underneath her skin.

A 32-year-old woman in Russian Federation took a selfie when she noticed a lump under her left eye. She finally visited a physician who reported a "superficial moving oblong nodule at the left upper eyelid". In humnans, D. repens usually manifests as either a wandering worm in the subcutaneous tissue or a granulomatous nodule, although there are reports of pulmonary dirofilariasis with this species. The agency further said that humans can at times get infected with the worm accidently. The CDC notes that treatment for humans typically involves removal of the nodule - such as with the Russian woman - with no other medical treatment usually necessary.

While the definitive hosts for this parasite are dogs and other carnivores, the report stated that humans can be "aberrant hosts".

This specific parasite is not found in the U.S., but can be found in Europe.

Medical experts agree this parasite is just another reason to do what you can to protect yourself from mosquito bites. In a 2009 case report, one strain of the parasite even caused meningoencephalitis, or inflammation of the brain and its surrounding membranes. The larvae then make their way into the mosquito's mouth parts and, Nolan said, when the mosquito bites an animal - or a human - they crawl quickly into the bite site.
