The medical term for a scab is an eschar. An eschar is a scab or dead tissue that falls off and exposes the healing tissue underneath. It is a natural part of the healing process, especially after a wound or burn. The formation of an eschar is a complex process involving various cellular and molecular mechanisms, including inflammation, coagulation, and tissue repair.
Understanding Eschar Formation

Eschar formation occurs when the body’s natural defense mechanisms are triggered in response to injury or damage. The process involves the activation of platelets, which release chemical signals that attract other cells, such as neutrophils and macrophages, to the site of injury. These cells work together to clean up debris, fight off infections, and promote tissue repair. As the healing process progresses, the eschar begins to dry out and contract, eventually falling off to reveal new tissue underneath.
Types of Eschar
There are different types of eschar, including:
- Dry eschar: A dry, scaly eschar that forms on the surface of a wound or burn.
- Wet eschar: A moist, soggy eschar that forms on the surface of a wound or burn, often indicating infection or delayed healing.
- Slough eschar: A type of eschar that forms on the surface of a wound or burn, characterized by a soft, wet, and often foul-smelling tissue.
| Eschar Type | Description |
|---|---|
| Dry Eschar | A dry, scaly eschar that forms on the surface of a wound or burn. |
| Wet Eschar | A moist, soggy eschar that forms on the surface of a wound or burn, often indicating infection or delayed healing. |
| Slough Eschar | A type of eschar that forms on the surface of a wound or burn, characterized by a soft, wet, and often foul-smelling tissue. |

Key Points
- Eschar is the medical term for a scab or dead tissue that forms on the surface of a wound or burn.
- Eschar formation is a natural part of the healing process, involving various cellular and molecular mechanisms.
- There are different types of eschar, including dry, wet, and slough eschar.
- Monitoring the eschar for signs of infection or delayed healing is crucial for promoting proper wound healing.
- Eschar formation can be influenced by various factors, including the severity of the injury, the presence of infection, and the overall health of the individual.
Treatment and Management of Eschar

Treatment and management of eschar depend on the type and severity of the eschar, as well as the underlying cause of the wound or burn. In general, treatment involves promoting a clean and moist environment, managing pain and discomfort, and monitoring for signs of infection or delayed healing. In some cases, surgical debridement may be necessary to remove dead tissue and promote healing.
Complications and Risks Associated with Eschar
Eschar formation can be associated with various complications and risks, including:
- Infection: Bacterial, viral, or fungal infections can occur if the eschar becomes contaminated or if the underlying tissue is not properly cleaned and managed.
- Delayed healing: Eschar formation can delay the healing process if the eschar is not properly managed or if the underlying tissue is not receiving adequate oxygen and nutrients.
- Scarring: Eschar formation can result in scarring, especially if the eschar is deep or extensive.
What is the difference between a scab and an eschar?
+A scab and an eschar are often used interchangeably, but an eschar refers specifically to a scab or dead tissue that forms on the surface of a wound or burn, while a scab can refer to any type of crust or covering that forms on a wound.
How long does it take for an eschar to fall off?
+The time it takes for an eschar to fall off can vary depending on the severity of the wound or burn, as well as the overall health of the individual. In general, an eschar can take anywhere from a few days to several weeks to fall off.
Can I remove an eschar myself?
+No, it’s not recommended to remove an eschar yourself, as this can lead to infection, delayed healing, and scarring. It’s best to seek medical attention from a qualified healthcare professional who can assess and manage the eschar properly.
