An 11-year-old boy breaks out quite suddenly with a rash of papulosquamous lesions with a silvery scale. Can you Dx?
An 11-year-old boy presents with a rash of tear-drop shaped scales spread symmetrically on his trunk and proximal extremities. The scale is adherent and attempts to scrape the lesions result in punctate bleeding. Other than a case of strep throat last week for which he was treated with antibiotics, he is otherwise in good health.
What is your diagnosis?
