Impetigo is a very contagious, superficial, bacterial skin infection that easily spreads among people in close contact.

Ecthyma is a deeply ulcerated form of impetigo that extends to the dermis.
It has "punched-out" ulcers with yellow crust and elevated violaceous margins.
Most cases occur in children and elderly.
It may be a de novo infection or superinfection.
