Ecthyma can occur from untreated impetigo that develops into a deeper infection.
Impetigo can establish as a primary infection when the microorganisms infects typical skin, or it can create as a second infection when germs gets into already irritated or open skin, such as from a wound, pest bite, toxin ivy, dermatitis, herpes, or scabies.
