A middle-aged woman presented with itchy, red, raised lesions on her waist for 10 days. Examination revealed a well-defined serpiginous erythematous tract on the left flank [Figure 1]. Polarised dermoscopy (Dermlite DL5, 10x magnification) showed fine white scaling arranged in a serpiginous fashion with brownish-black dots and clods along the length [Figure 2a]. These brownish-black dots indicate spongiotic dermatitis, accompanied by an inflammatory infiltrate, vasodilation, red blood cell extravasation, and hemosiderin deposition. The parallelly arranged brown clods correspond to the helminth’s body. Ultraviolet fluorescence dermoscopy revealed bluish fluorescence along the tracts, and enhanced visibility of hidden larval tracts [Figure 2b]. This technique aids in identifying the advancing larvae, guiding targeted biopsies, and facilitating appropriate treatment.

- Dermoscopy of the lesion (Dermlite DL5, ultraviolet mode, 10x magnification) shows the presence of bluish fluorescence overlying the serpiginous tracts (arrow) along with visualisation of the hidden larval tract (rectangle) originating from the previously thought area of termination (circle).
