Synopsis

Ecthyma is a bacterial skin infection caused by beta-hemolytic streptococci and often secondarily contaminated with staphylococci. It is seen from infancy to the teenage years. This infection is predisposed by poor hygiene, malnutrition, and trauma to the tissues. The lower extremities are sites of predilection.
