Origin: [NL., fr. Gr. pimple, fr. to break out.]
Ecthyma is an ulcerative pyoderma of the skin caused by bacteria such as Pseudomonas, Streptococcus pyogenes, and Staphylococcus aureus. Because ecthyma extends into the dermis, it is often referred to as a deeper form of impetigo. Causes include insect bites and an ignored minor trauma. Wound cultures usually reveal that the lesions are teeming with bacteria. Ecthyma describes ulcers forming under a crusted surface infection. The site may have been that of an insect bite or of neglected minor trauma. It is treated by antibiotics like cloxacillin, erythromycin, and cefalexin. Psuedomonas infections are often treated with two antibiotics due to frequent resistance. Ecthyma has a predilection for children and elderly individuals. Outbreaks have also been reported in young military trainees Ecthyma usually arises on the lower extremities of children, persons with diabetes, and neglected elderly patients. During wartime in tropical climates, ecthymatous ulcers are commonly found on the ankles and dorsa of the feet.
