Ecthyma

This is a deeper form of impetigo. It occurs in the epidermis as well as in the dermis, producing a superficial ulcer that becomes secondarily crusted. It usually occurs secondary to trauma and is most commonly seen with poor hygiene. The lesions will often last for many weeks becoming essentially ulcerated and may even scar the skin. Secondary cellulitis and osteomyelitis are very uncommon developments.

Treatment:

Oral antibiotics such as Cloxacillin or Keflex are often required
