Pyoderma is obtained from two words “pyo” means pus and “derma” means skin, so pyoderma is any skin condition where you see pus due to some bacterial infections. Mostly the culprit bacteria is Staphylococcus Epidermidis or Staphylococcus Aureus.
Below is the photograph of a 12 year old boy where you see multiple pyoderma on face, covering forehead, and danger area of face too. Many of you may say them to be furuncle but they are not furuncles or boils as boils are around hair follicles. Boils are also bumpy red, pus filled highly tender, and warm on touch. When these boils occur recurrently condition is called as chronic furunculosis. And when these boils occur in hospital setting condition is known as hospital furunculosis.
Treatment:small sized regress themselves by giving broad spectrum antibiotics, little big sized need drainage, or you can ask patient to apply cloth soaked in warm water which promotes its drainage or you can give incision and drainage so as to drain.
