Thirty clinical vignettes on pigmented skin lesions. Each case carries a presentation, the clues that narrow it — age, skin type, site, how the lesion behaves with the seasons — 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. Several cases hinge on the pairs this deck most invites confusion between: ephelides against lentigines by whether they fade when the sun goes, lentigo simplex against solar lentigo by border and size, dermatosis papulosa nigrans against small seborrheic keratoses, and blue against pigmented spindle cell and Spitz naevi by color, site and age. Every question cites its slide.
