Invertebrate

These lesions are very common in children, but if a multitude spring up in an adult, you have to assess for HIV (or other form of immunosuppression). Common areas of involvement include the trunk, axillae, antecubital and popliteal fossa, and crural folds.

Challenge: What is the etiology of this lesion?

This is molluscum contagiosum, caused by a poxvirus, characterized by flesh-colored, firm, dome-shaped 2-5mm papules with an umbilicated center.
