Ecthyma gangrenosum

Ecthyma gangrenosum is a type of skin infection that is often associated with Pseudomonas aeruginosa, a type of bacteria. It is characterized by small, red, painful skin lesions that quickly evolve into necrotic ulcers with a black center.

Causes[edit | edit source]

Ecthyma gangrenosum is most commonly caused by Pseudomonas aeruginosa, but it can also be caused by other types of bacteria, including Staphylococcus aureus, Escherichia coli, and Klebsiella pneumoniae. It is often seen in patients with immunodeficiency, particularly those with neutropenia or sepsis.

Symptoms[edit | edit source]

The initial symptoms of ecthyma gangrenosum include small, red, painful skin lesions. These lesions quickly evolve into necrotic ulcers with a black center. Other symptoms may include fever, malaise, and bacteremia.

Diagnosis[edit | edit source]

The diagnosis of ecthyma gangrenosum is typically made based on the characteristic appearance of the skin lesions. Biopsy of the lesion and culture of the bacteria can confirm the diagnosis.

Treatment[edit | edit source]

Treatment of ecthyma gangrenosum involves antibiotic therapy to treat the underlying bacterial infection. In severe cases, surgical debridement of the necrotic tissue may be necessary.

Prognosis[edit | edit source]

The prognosis of ecthyma gangrenosum depends on the underlying cause and the patient's overall health. With prompt and appropriate treatment, the prognosis can be good. However, in patients with severe immunodeficiency or sepsis, the prognosis can be poor.
