Correct Answer:

Wet gangrene

Description:

Although gangrenous necrosis is not a distinctive pattern of cell death, the term is still commonly used in clinical practice. It usually refers to the condition of a limb (generally the lower leg) that has lost its blood supply and has undergone coagulative necrosis involving multiple tissue layers. When bacterial infection is superimposed, the morphologic appearance changes to liquefactive necrosis because of the destructive contents of the bacteria and the attracted leukocytes (resulting in so-called “wet gangrene”).
