Polarized and Ultraviolet-induced Fluorescence Dermoscopy in Genital Nodular Scabies in Skin of Color: An Objective Tool for Diagnosis and Monitoring Treatment Response

Abstract Background: Nodular scabies is conventionally regarded as a post-scabietic hypersensitivity reaction rather than active infestation. Consequently, management often relies on treatment history. Polarised and ultraviolet-induced fluorescence (UVF) dermoscopy may provide objective evidence of persistent mites and guide therapy.
