Slough is yellowish and soft and is composed of pus and fibrin containing leukocytes and bacteria. This tissue often adheres to the wound bed and cannot be easily removed.

How quickly does necrosis occur?

Soft tissue necrosis usually begins with breakdown of damaged mucosa, resulting in a small ulcer. Most soft tissue necroses will occur within 2 years after radiation therapy. Occurrence after 2 years is generally preceded by mucosal trauma.

Does a wound turn white when healing?

As it heals, the new skin sometimes appears yellowish and may be confused with pus.

There is a consequence when cells don’t die an apoptotic death. Cells release a bunch of hazardous molecules when they die by necrosis. A new theory describes that necrotic death and chronic inflammation may foster the onset and growth of tumors.
