I read with interest the recent article by Fu et al1 concerning the finding of “dirty dots” in scalp dermoscopy in children. When using the dermoscope to examine for head lice and nits (which are currently rampant in our schools) in my 2 sons, aged 8 and 6 years, I have found similar dirty dots. Indeed, when I have looked at the rest of their skin (assuming I can catch them for long enough), I have seen similar findings. It appears to be more severe after a day in the backyard, garden, or paddock. In Australia, we simply call this dirt. Most of the dirty dots disappear after a bath or shower but by no means all. As our children grow up and learn how to wash properly, we anticipate a complete cure.
