Thirty clinical vignettes on dermatological infestations. Each case carries a presentation, the clues that narrow it — travel, geography, season, occupation, age — and the defining feature it turns on. The lead-in varies deliberately: some ask for the diagnosis, others for the next step, the treatment, the test, or what you would tell the patient. Geography does a lot of work in this lecture — the brown recluse in the Midwest and Southeast against the hobo spider in the Pacific Northwest, Lyme disease in the Northeast against Rocky Mountain spotted fever in the Southeast, tungiasis after tropical travel against cutaneous larva migrans from the same beach. Every question cites its slide.
Answers reveal only after you choose. Your score and a breakdown by objective appear at the end, with a review of everything you missed.
