1B73.1/B08.0 Staphylococcal ecthyma



Staphylococcal ecthyma is an infection of the skin caused by the bacteria Staphylococcus aureus. The bacteria can enter the skin through small cuts or abrasions.


The diagnosis of staphylococcal ecthyma is usually made based on the patient’s history, physical examination, and laboratory tests. The patient may have a history of skin lesions, or they may present with a rash or lesions on their skin. Laboratory tests may include a culture of the skin lesions or a swab of the lesion.

Differential diagnosis

Differential diagnoses include other skin infections, such as impetigo, cellulitis, and herpes simplex virus infection.


Treatment of staphylococcal ecthyma usually involves antibiotics, such as penicillin or cephalosporins. Antibiotic creams or ointments may also be used to treat the infection.


The prognosis of staphylococcal ecthyma is generally good with appropriate treatment. However, the infection may recur if the underlying cause is not addressed.
