Answer: B - Liquefaction necrosis is an indication that the chemical is still burning the patient. Exposure to acids or heat causes thick, leathery eschars to form. Thermal injury can lead to cherry red, firm tissue. Partial-thickness thermal injury leads to intact blisters.
Liquefactive necrosis or colliquative necrosis results in a transformation of the tissue into a liquid viscous mass. Often liquefactive necrosis is associated with focal bacterial or fungal infections, and can also manifest as one of the symptoms of an internal chemical burn such as the one in this example.
