This 9-year-old boy presented with history of painful skin lesions on right ear and umbilicus of 3 days duration. He gave history of having been to Jim Corbett National Park 5 days back with family. There was associated pain below umbilicus and right side of face. Dermatological examination revealed two dark coloured nodules on umbilicus [Figure 1]a and upper part of right ear [Figure 1]b. With suspicion of tick infestation dermoscopy was done using Dermlite DL4 polarized light magnification 10x [Figure 1]c and [Figure 1]d. The ticks were identified [Figure 1]e and [Figure 1]f and removed with the help of forceps. The ticks were of the Argasidae genera (soft ticks) with no hard shell, legs located on the underside of the body and lateral rounded body edges.[1],[2] Dermoscopy can help in confirming the diagnosis of tick infestation as sometimes naked eye and the magnifying lens may not give a very clear picture.

(e) Ticks from both the lesions with the left one from the ear being much larger due to larger volumes of blood intake. (Magnification 20x). Zoom of Galaxy J8 mobile camera used to magnify image.
