Recently, a 32-year-old woman in Russia noticed a lump on her skin that seemed to migrate on a daily basis. At first, it started out as a small bump beneath her left eye. It caused some itching and swelling.
Five days later, the lump moved to the top of her eye, just above the eyelid. It stayed there for the next ten days before migrating again to her top lip, causing it to swell several times beyond its normal size.
