Abstract	Pseudofolliculitis barbae (PFB) is a chronic inflammatory disorder of follicular and perifollicular skin characterized by papules, pustules, and post-inflammatory hyperpigmentation. It occurs more frequently in men of African and Asian descent. The etiology of PFB is multifactorial. Shaving or plucking the hair precipitates the onset of an inflammatory reaction that results from the penetration of the adjacent skin by the growing sharp tips. The curved shape of the hair follicle allows for the downward curvature and penetration of the growing hair tips into the skin. The onset of the foreign body reaction leads to itching and the development of papules, pustules, and post-inflammatory hyperpigmentation, especially in the beard area although other shaved areas of the body may be affected. Keloids have also been known to develop after the onset of PFB, giving rise to extensive unsightly scars. Diagnosis is clinical. Cessation of shaving or removal of the involved hair follicles usually terminates the development of PFB. Individuals with the single nucleotide substitution in the hair follicle companion layer specific keratin gene (K6hf) have a six fold increased chance of developing PFB.

Abstract	The African black soap is popular for its cleansing and medicinal properties particularly amongst those of African descent. The "traditional" African black soap" refers to soaps made from the ash-derived alkali from agricultural waste and oil extracted from vegetable matter without the addition of cosmetic enhancing products. Production of black soap has been traced to west Africa especially Nigeria and Ghana. The raw materials are readily available in the region making the soap available and affordable for most in sub-Saharan Africa. It has been described as gentle, super fatted and hypoallergenic. It is advertised as antimicrobial, anti-acne, exfoliating, skin toning, scar fading, and having medicinal properties. It is popular for its management of skin diseases, although some of the claims remain anecdotal. Generations of Africans abroad continue to use modified versions of the soap and claim they are satisfied with the results obtained. However, in the management of patients with skin disorders, especially eczema, in sub-Saharan Africa, prescribing an ideal skin cleanser can be challenging as many cannot afford the imported nonsoap cleansers with skin friendly pH. Studies have shown that the traditional black soap does have antimicrobial properties against Staphylococcal and some Streptococcal organisms, which are commonly seen in the tropical climate. The recent ban of some antiseptics in popular antibacterial soaps in this environment, emphasizes the need for production of safer antimicrobials. The antimicrobial, physiochemical, and phytochemical properties of the African black soap suggest it may have beneficial effects on the overall skin health.

Abstract	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. However, a few inciting agents have been suggested which include androgens, inflammation, infection, trauma, genetics, and ingrowing hairs. AK shares some similar features with other forms of cicatricial alopecia and may occur together. Papules, pustules, and sometimes tumorous masses in the nuchal or occipital regions of the scalp hence the name "bumps" evolved in the environment. Despite its common occurrence, only a few seek help in hospital when lesions start to unsightly affect the individual's quality of life. The presences of the keloidal lesions are more stressful compared to the resulting alopecia. Various attempts to reduce the bumps with corrosives, acids, and car engine oils lead to larger lesions or unsightly scars. Active lesions produce bleeding during haircuts. This is worrisome as a couple of individuals with active AK share shaving instruments at the barber shop and are at risk of acquiring or transmitting blood-borne infections. There is an urgent need to encourage safe shaving habits and treatment of lesions at onset so as to prevent unsightly lesions.

Abstract	Cutaneous metastases are an uncommon feature of solid organ malignancies. The cost of multiple investigations and prolonged processing time of biopsies may lead to diagnostic delays especially in resource limited practice settings. Dermoscopy can provide useful clues and has been found to be useful in the diagnosis of cutaneous metastases. Dermoscopic findings of skin lesions may limit unnecessary investigations and shorten time to diagnosis. There are limited data on dermoscopic features of embryonal rhabdomyosarcoma in the literature. We report dermoscopic features of cutaneous metastasis of embryonal rhabdomyosarcoma seen in a black African child.

Abstract	Background: Facial acne vulgaris is the most common disease of the skin in adolescents. In Nigeria, studies of the prevalence of adolescent facial acne vulgaris, lesion type and distribution, and influence of social class on prevalence are few. The aim of this study was to determine the prevalence of adolescent facial acne vulgaris, clinical characteristics, and the influence of social class on this prevalence. Methods: This was a community-based cross-sectional study. One thousand and seventy-nine students from four secondary schools (two private and two public) were assessed. Students were clinically examined for facial acne vulgaris, and acne severity was graded. A structured questionnaire for sociodemographic variables was administered to the students. Data were analyzed using SPSS 16. Results: One thousand and seventy-nine students were studied; 52% were male, and 47.9% were female. The students were aged 9–20 years with a mean age of 14 ± 2.1 years. The prevalence of facial acne vulgaris was found to be 53.2%. More females (56.7%) had acne than males (50%), the prevalence was found to increase from 28% in the 9–11 years age group to 71.1% in the 18–20 years age group and more prevalent in adolescents from the high social class (60.7%). The severity of acne was mild in 67.2%, moderate in 28.9%, and severe in 4.9%. Conclusion: Prevalence of adolescent facial acne vulgaris increases with age, more prevalent in adolescents from a high social class. Male gender, age, a family history of acne, and previous treatment of acne contribute to the severity of acne.

Abstract	Introduction: Hairdressing is associated with a wide range of disorders. This is particularly true in the African hairdresser, who is saddled with the responsibility of 'taming' the rather difficult-to-manage African hair, and is thus exposed to a wide range of chemical, biological and physical materials in the hair grooming process. We therefore sought to determine the prevalence and pattern of occupational skin disorders among hairdressers in Ibadan, one of the oldest and largest cities in Nigeria. Methods: This was a cross sectional study of hairdressers conducted in 2013 in Ibadan, Nigeria. Hairdressers and their apprentices were interviewed using a structured questionnaire, following which a thorough physical examination was performed to identify any skin disorder. Results: A total of 226 hairstylists were recruited. The prevalence of occupational skin disorders in the study was 68.13%. The prevalence of specific skin disorders was 32.74% for nail disorders; 28.75% for traumatic skin disorders; and 2.64% for hand dermatitis. Conclusion: There is a high prevalence of occupational skin disorders among hairdressers, and this may have personal and public health implications.

Abstract	Androgenetic alopecia is a highly heritable trait. However, much of our understanding about the genetics of male pattern baldness comes from individuals of European descent. Here, we examined a novel dataset comprising 2,136 men from Ghana, Nigeria, Senegal, and South Africa that were genotyped using a custom array. We first tested how genetic predictions of baldness generalize from Europe to Africa, finding that polygenic scores from European GWAS yielded AUC statistics that ranged from 0.513 to 0.546, indicating that genetic predictions of baldness in African populations performed notably worse than in European populations. Subsequently, we conducted the first African GWAS of androgenetic alopecia, focusing on self-reported baldness patterns at age 45. After correcting for present age, population structure, and study site, we identified 266 moderately significant associations, 51 of which were independent (p-value < 10
