Thirty clinical vignettes on Dermatology II. Each case carries a presentation, the clues that narrow it — age, drug exposure, timing, light history — 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 initial or confirmatory test, or what you would tell the patient. Read the lead-in carefully; recognizing the disease and answering the question are two separate acts. Several cases hinge on discriminations this lecture makes explicitly — Stevens-Johnson syndrome against toxic epidermal necrolysis by body surface area, phototoxicity against photoallergy by mechanism and timing, solar lentigo against lentigo maligna on dermoscopy. Every question cites its slide.
