If you see any changes in the color of your wound , contact your doctor immediately. Scabs are found on superficial or partial-thickness wounds and they develop when a crust has formed by coagulation of blood or exudate. A scab is the brown, dry crust that forms over any injured surface on skin, typically within 24 hours of injury. In less than 10 seconds after a break in the skin, the body does two things. It uses sticky blood cells called platelets to prevent an extended amount of blood loss from the wound.

The body also deploys white blood cells to attack any outside substances that may have snuck in before the clot was fully formed. To hold the clot in place, a thread-like protein called fibrin begins to from a structure throughout the clot. Angiogenesis is the process by which new blood vessels form, bringing in tiny capilarry buds that appear as granular tissue. Granulation tissue sets the stage for epithelial tissue to be laid down on top of the wound bed. Pale, unhealthy granulation tissue, as noted above, can result from lack of good blood supply and angiogenesis.

Pale granulation tissue needs to be freshened up with debridement to stimulate new ingrowth of blood vessels. Pictured on the left is a necrotic sacral ulcer. The necrosis can be best visualized to the left of the wound in the photograph. Necrosis is usually dark tissue, which is completely devitalized.

Necrotic tissue forms as a result of tissue death from damage. For pressure ulcers, the underlying pressure causes occlusion of blood vessels blocking vital oxygen delivery to tissues. This occlusion results in tissue death and subsequent bacterial overgrowth. In order for wounds to heal, all necrotic tissue should be debrided from the wound, a process that may take multiple attempts over months to achieve the desired outcome of good healthy granulation tissue.
