Pyogenic granuloma of the cornea induced by "snake oil".

A pyogenic granuloma of the cornea developed on the vascularized cornea of a 79-year-old woman after "snake oil" accidentally dripped in her eye. The snake oil was being used to relieve forehead pain, which may have been referred. The five previously reported examples of corneal pyogenic granuloma are similar to this case in that trauma preceded development of the lesion. However, the chemical trauma induced by the snake oil appears to be a unique mechanism of injury.
