Final answer:
Acne keloidalis nuchae is a condition featuring inflamed bumps and keloid-like scars on the back of the neck, arising from an overproduction of scar tissue following an initial skin injury or irritation.
Step-by-step explanation:
Acne keloidalis nuchae is a chronic skin condition characterized by inflamed bumps and keloidalis formation on the back of the neck (nuchae). This condition occurs when excessive scar tissue forms as the result of the body's healing process to an initial skin trauma or irritation, often associated with short, curly hairs penetrating the skin. Unlike typical acne, which results from infected sebaceous glands and can appear anywhere on the body rich in these glands, acne keloidalis nuchae specifically affects the neck area and leads to the development of keloid-like scars.
In general, acne is a skin disturbance caused by clogged, sebum-filled pores that provide a perfect environment for the growth of bacteria like Propionibacterium and Staphylococcus. The bacterial infection triggers the immune system to respond with inflammation. When the inflammation heals but the process of collagen formation does not cease, a raised scar tissue known as a keloid can develop. As a result, the keloids associated with acne keloidalis nuchae are typically raised, lumpy, and can become larger and more pronounced over time.
Due to its aesthetic and sometimes painful nature, acne keloidalis nuchae can lead to psychological stress and discomfort, emphasizing the need for appropriate treatment and management strategies.
