Dermoscopic characteristics of cutaneous larva migrans in dark skin: a study from Banjul, The Gambia.

Cutaneous larva migrans (CLM) results from hookworm larvae infestation, mainly Ancylostoma braziliense or Ancylostoma caninum. It is common in Sub-Saharan Africa, often acquired through soil contact, especially in sandy beaches, manifesting as serpiginous, erythematous and intensely pruritic tracts within the epidermis, and presenting with diverse clinical appearances. Diagnosis is mostly clinical; however, dermoscopy can enhance diagnostic accuracy and distinction from mimics. The current body of literature is deficient in its representation of dermoscopic data for CLM in Black patients. This study explores dermoscopy in nine dark-skinned patients with 16 CLM lesions. Distinctive serpiginous structureless areas displaying a range of colours, peripheral scales surrounding brown areas and brown dots were predominant features, whereas vascular characteristics were less evident. This article highlights the presence of distinct reaction patterns, including brown dots, scales, and accentuated, often disrupted brown reticular lines in addition to the characteristic winding tracts in darker skin.

African black soap: Physiochemical, phytochemical properties, and uses.

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.
