Insect bite reaction - close-up

Overview

This is a 2 to 3 centimeter wide blood-filled (hemorrhagic) blister (bullae) that has resulted from an insect bite. It is located on the wrist. Bullae formation and tissue necrosis (death) are more common with spider bites, but may also be caused by insect bites.
