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.
