Necrosis can also result from chemical trauma, with alkaline and acidic compounds causing liquefactive and coagulative necrosis, respectively, in affected tissues. The severity of such cases varies significantly based on multiple factors, including the compound concentration, type of tissue affected, and the extent of chemical exposure.
Initial skin findings include red-purple, dusky, flat spots known as macules that start on the trunk and spread out from there. These skin lesions then transform into large blisters . The affected skin can then become necrotic or sag from the body and peel off in great swaths.
