Epidermal necrosis found on histology is a sensitive but nonspecific finding for TEN. [7]
Causes include: acute pancreatitis, where methemalbumin formed from digested blood tracks around the abdomen from the inflamed pancreas; bleeding from blunt abdominal trauma; bleeding from aortic rupture; bleeding from ruptured ectopic pregnancy; Importance of the sign is on a decline since better diagnostic modalities are now available.
