Ulcerating, "punched out" looking ulcers. In and of itself, the term "ecthyma" is a morphological term. A distinction is made between ecthymata contagiosum (Orf), which is triggered by poxviruses, ecthymata gangraenosum (intertriginous ulcerations triggered by Pseudomonas aeruginosa) and ulcerations triggered by group A streptococci and staphylococci, which are referred to as ecthymata simplex.
Group A streptococci, less frequently Staphylococcus aureus, invade the skin via injuries. The most common location is the lower leg, but skin lesions can occur at any location.
Initially, vesicles and pustules may appear. As the pathogens progress, they work their way into the subcutaneous tissue, which is why coin-sized, smeary, sometimes honey-yellow crusted, purulent, necrotic, punched-out-looking ulcers with halo-like margins develop. Lymphangitis or locoregional lymphadenopathy may be associated
