    Large café-au-lait macules with irregular 'coast of Maine' borders are characteristic of McCune-Albright syndrome.

  3. An infant presents with a rapidly enlarging strawberry-red plaque on the face. Which complication warrants urgent systemic beta-blocker therapy?

    Answer: Periocular location threatening the visual axis

    Eczema herpeticum is a disseminated HSV infection over eczematous skin requiring systemic acyclovir.
