A 45-year-old Indian woman presented with intensely itchy linear red rash on the abdomen of five days duration. Dermatological examination revealed a well-defined elevated erythematous serpentine to bizarre tract of 2-3 mm width and 12 cm in length on an erythematous background. There were crusted erosions and scaling proximally and multiple pustules in a linear fashion on the distal end located on the right lumbar region [Figure 1]. Dermoscopy (Illuco IDS 1100, ×10 polarised) of centre of the lesion showed well-defined segmented yellowish-white linear structure which may correspond to larval body with a pinkish erythematous background and brown dots with peripheral white scales that correspond to empty larval tract [Figure 2a]. Dermoscopy of distal half of the lesion showed multiple segmented yellowish linear areas which correspond to pustules along the larval tract probably due to intense inflammatory reaction to the larva [Figure 2b]. This might be a peculiar finding which has not been described previously in the literature. Although the diagnosis of cutaneous larva migrans is clinical in most of the cases, dermoscopy can prove to be a useful adjunct in confirming the active or residual stage of the infestation.
