A 12-year old boy is brought to the clinic by his father to get treatment for this condition on his face. What is the most appropriate morphologic term for these lesions?

Pustules are raised lesions containing purulent exudate; vesicular processes such as varicella or herpes simplex may evolve to pustules A circumscribed lesion that contains purulent material. It may occur within a pilosebaceous follicle or a sweat duct or, less often, on glabrous skin. Most commonly due to infections, but some eruptions typically cause sterile pustules.
