Keloid Scar

Overview

A keloid scar is a type of skin lesion that is characterized by the formation of a thick, raised scar. It can occur anywhere on the body, but it is most commonly seen on the earlobes, shoulders, cheeks, and chest. Keloid scars are not harmful to physical health, but they can cause significant emotional distress.

Types of Keloid Scar

Keloid scars are classified into two main types:

1. Hypertrophic scars and
2. Keloid scars. Hypertrophic scars are thickened scars that form at the site of a wound, while keloid scars are more complex and can form on any part of the body.

Causes of Keloid Scar

The exact cause of keloid scars is not fully understood, but it is believed to be related to the overproduction of collagen in the skin. This can occur due to a variety of factors, including:

• Genetic predisposition: Some individuals may be more prone to developing keloid scars due to their genetic makeup.
• Hormonal changes: Hormonal fluctuations during puberty, pregnancy, or menopause can contribute to the development of keloid scars.
• Injury or trauma: Physical trauma, such as cuts or burns, can cause keloid scars to form.
• Skin conditions such as acne or eczema: These conditions can cause inflammation and scarring in the skin.
• Poor wound care: Failure to properly clean and dress wounds can lead to infection and scarring.

Risk Factors of Keloid Scar

Certain individuals may be at higher risk of developing keloid scars. These include:

• Those with a family history of keloid scars: Individuals with a family history of keloid scars may be more likely to develop them themselves.
• Individuals who have had previous injuries or trauma: Those who have had previous injuries or trauma may be more likely to develop keloid scars.
• People with certain skin conditions such as acne or eczema: Those with skin conditions that cause inflammation and scarring may be more likely to develop keloid scars.
• Those who are prone to forming scar tissue: Some individuals may be more prone to forming scar tissue due to their genetic makeup or other factors.

• Physical examination: A physical examination is typically performed to assess the appearance and size of the scar.
• Medical history: A medical history is taken to determine if there are any underlying medical conditions that may be contributing to the development of the scar.
