Peculiar circular and C-shaped injuries on a body from the sea.

A case where a body with unusual circular injuries was found in the sea is presented. The victim was a 60-year-old woman who had been depressed and had attempted suicide before. She was missing for 6 days before the corpse was found. The body had several almost perfectly circular injuries and C-shaped incision injuries with almost circular flaps of skin. We concluded that the cause of the peculiar circular injuries might be bite marks of Isistius spp. (I. brasiliensis and/or I. plutodus), commonly known as cookie-cutter shark because of its very unusual feeding style.
