Keloid acne scar

Adebola Ogunbiyi
Acne keloidalis nuchae (AKN) also known as folliculitis keloidalis nuchae (FKN) is a chronic form of scarring folliculitis seen mostly in men of African descent. The term AKN is commonly used even though the condition is not a keloid, and the affected individuals do not have a tendency to develop keloids in other areas of the body. It is seen in post pubertal men and is rare after the age of 55 years. A few cases have been reported in females. which has been classified as a primary cicatricial alopecia since the exact cause of acne keloidalis (AK) remains unknown...

Keloids and hypertrophic scars are fibroproliferative disorders (FPDs) of the skin that result from abnormal healing of injured or irritated skin. They can be called pathological or inflammatory scars. Common causes are trauma, burn, surgery, vaccination, skin piercing, folliculitis, acne, and herpes zoster infection. The pathogenesis of these scars clearly involves local conditions such as delayed wound healing, wound depth, and the tension of the skin around the scars. Scar severity is also shaped by interactions between these local factors and genetic and systemic factors such as hypertension and sex hormones...

BACKGROUND: Keloid is a benign fibrous growth, which presents in scar tissue of predisposed individuals. It is a result of irregular wound healing, but the exact mechanism is unknown. However, several factors may play a role in keloid formation. To date, there are no studies of keloids in Syria, and limited studies on Caucasians, so we have investigated the risk factors of keloids in Syrians (Caucasians), and this is the main objective of this study. METHODS: Diagnosis of keloids was clinically made after an interview and physical examination...

Keloids are common in the Asian population. Multiple or huge keloids can appear on the chest wall because of its tendency to develop acne, sebaceous cyst, etc. It is difficult to find an ideal treatment for keloids in this area due to the limit of local soft tissues and higher recurrence rate. This study aims at establishing an individualized protocol that could be easily applied according to the size and number of chest wall keloids.A total of 445 patients received various methods (4 protocols) of treatment in our department from September 2006 to September 2012 according to the size and number of their chest wall keloids...

BACKGROUND: Acne vulgaris is a chronic inflammatory disease characterized by non-inflammatory and inflammatory lesions that can cause scarring. Oral isotretinoin is the current recommended treatment for moderate and severe cases; however, there are reports of possible influences on the healing process of the skin, leading to an increase in the risk for hypertrophic scars and keloids. This hypothesis, although unproven, represents a contraindication to the treatment of acne scars during the 6-12 months after the cessation of isotretinoin...

BACKGROUND: Scars appear as a result of skin damage during the process of the skin healing. There are two types of acne scars, depending on whether there is a loss or accumulation of collagen: atrophic and hypertrophic. In 80-90% it comes to scars with loss of collagen compared to smaller number of hypertrophic scars and keloids. AIM: The aim of the study was to determine efficiency and safety of fractional carbon dioxide laser in the treatment of acne scars. MATERIAL AND METHODS: The study was carried out in Acibadem Sistina Clinical Hospital, Skopje at the Department of Dermatovenerology, with a total of 40 patients treated with fractional carbon dioxide laser (Lutronic eCO2)...

BACKGROUND: Acne scarring can be classified into atrophic icepick, boxcar, and rolling scars in addition to keloidal and hypertrophic scars. Additionally, these scars can be erythematous, hyperpigmented, and/or hypopigmented. Each scar type has a different structural cause warranting a customized approach. Many cosmetic options exist to address these changes individually, but little literature exists about the safety and efficacy of combining such procedures and devices. METHODS: A Medline search was performed on combination treatments because it relates to facial acne scarring, and results are summarized...

BACKGROUND: Acne scarring is a frequent complication of acne and resulting scars may negatively impact on an affected person's psychosocial and physical well-being. Although a wide range of interventions have been proposed, there is a lack of high-quality evidence on treatments for acne scars to better inform patients and their healthcare providers about the most effective and safe methods of managing this condition. This review aimed to examine treatments for atrophic and hypertrophic acne scars, but we have concentrated on facial atrophic scarring...

BACKGROUND: Folliculitis keloidalis nuchae (FKN) also known as acne keloidalis is the commonest form of scarring alopecia occurring in African males. It occurs mostly in individuals of African descent. Its prevalence ranges from 1·6% to 16·1%. FKN is multifactorial in origin: androgens, inflammation, trauma, ingrowing hairs and secondary infection have all been implicated in its aetiology. The reason for its occurrence in the occipital region is unclear although elevated androgens in the scalp have been suggested...

Hidradenitis Suppurativa (HS) is an uncommon disease, which is particularly rare in young and prepubescent children. HS pathology centers on the follicular unit and involves aberrant cutaneous cellular immunity. HS tends to first manifest in puberty, but a handful of prepubescent cases of HS have been reported and are linked to hormonal disorders, in particular elevated testosterone. The most common manifestations of HS are abscesses, scarring, acne inversa, and keloids, especially in the intertriginous areas of the groin and the axilla...

The skin is a dynamic and complex organ that relies on the interrelation among different cell types, macromolecules, and signaling pathways. Further, the skin has interactions with its own appendages and other organs such as the sebaceous glands and hair follicles, the kidney, and adrenal glands; systems such as the central nervous system; and axes such as the hypothalamic-pituitary-adrenal axis. These continuous connections give the skin its versatility, and when an injury is caused, some triggers start a cascade of events designed to restore its integrity...

Acne is the most common skin disease, affecting up to 95% of adolescents. Severe episodes of acne can cause considerable physical and psychological scarring, and overexpression of transforming growth factor-β can lead to formation of hypertrophic scars and keloids. The severity of acne in adolescence is associated with a positive history of severe acne in first-degree relatives, especially the mother. In most cases acne is a chronic disease, and it is often a component of systemic diseases or syndromes. All forms of severe acne require systemic treatment...

BACKGROUND: Because acne scarring is associated with substantially reduced quality of life, early initiation of effective treatment is desirable. In previous reports, isotretinoin treatment was associated with increased scarring after cosmetic procedures, such as laser treatment, dermabrasion, and chemical peeling. OBJECTIVE: To evaluate wound healing after ablative carbon dioxide (CO2) fractional resurfacing for acne scarring conducted during and/or within 1 to 3 months of oral isotretinoin treatment...

BACKGROUND: Skin disorders are common in adolescents, and the impact on quality of life can be enormous, particularly when viewed against the backdrop of the visibility of skin diseases and the psychologically vulnerable period of adolescence. However, few studies have documented the magnitude of skin disorders in this subset of individuals. We therefore estimated the point prevalence and pattern of dermatologic conditions in adolescents attending various secondary schools in Calabar, Southern Nigeria...

BACKGROUND: Consensus concerning nomenclature and classification of acne scars is lacking. Classification based solely on clinical examination represents an unmet need that could be improved with the use of objective, reproducible assessments. OBJECTIVE: To assess clinical and ultrasound morphologic features in 41 patients with scars resulting from moderate to severe acne and to determine whether correlation exists. MATERIALS AND METHODS: Eighty-one lesions clinically identified as boxcar, ice pick, rolling, hypertrophic, or keloidal were evaluated using high-frequency ultrasound (22 MHz)...
