A Young Male with a Rash of Scales

The asymptomatic rash came on quickly and is prominent on the boy's trunk and arms. Close-ups of the lesions in these slides may help you make the Dx.

Mike is 11-years-old and is accompanied by his mother who is very worried about a rash that appeared quite suddenly and has spread over his trunk and his arms. Other than dandruff, he has no history of skin problems. Mike has no other symtpoms, but he is very concerned about the way the rash looks; he says it's "scaly." The slides above offer you a close look at Mike's "scales" and some history. Put the pieces together and, what's your diagnosis?
