A rare and bizarre case of parasitic infection has left medical professionals stunned. In Romania, a woman presented to an ophthalmologist with a hard lump in her temple that had vanished just days earlier. The next day, doctors discovered a 4-inch-long living worm wriggling under her eyelid.
The patient's symptoms began when she noticed the lump in her temple a month prior, which disappeared within a day before the worm reappeared in her eye. After surgical removal of the worm, doctors identified it as Dirofilaria repens, a parasite typically found in dogs and other canines.
However, this is not the first time humans have been infected with this parasite. While dirofilariasis is rare in humans, it can occur when larvae are deposited under the skin by mosquitoes. The infected individual's immune system responds to the parasites, causing inflammation and swelling.
Researchers attribute the resurgence of dirofilariasis to climate change and globalization, which may be allowing the parasite to spread into new regions. In Europe, cases have been reported in Estonia, Lithuania, Latvia, and Finland, with some researchers speculating that humans may now serve as a host for this parasite.
Fortunately, treatment is available and effective, with surgery and anti-parasitic medication able to resolve the issue. For Americans, however, dirofilariasis remains a distant concern, as it has not been reported in the US.
In related news, researchers have identified other relatives of Dirofilaria repens that can infect humans in North America. While these parasites are distinct from Dirofilaria repens, they share similar symptoms and require prompt treatment to avoid serious complications.
