Aetiology
Cutaneous listeriosis is caused by the bacteria Listeria monocytogenes, which is found in soil, water, and food, including unpasteurized milk, soft cheeses, and deli meats.
Diagnosis
Cutaneous listeriosis is diagnosed based on a patient’s history and physical examination. If necessary, a skin biopsy may be taken to confirm the diagnosis.
Differential diagnosis
Differential diagnoses for cutaneous listeriosis include cellulitis, herpes zoster, erysipelas, and other bacterial infections of the skin.
Treatment
Cutaneous listeriosis is usually treated with antibiotics such as ampicillin or penicillin. In some cases, surgery may be necessary to remove infected tissue.
Prognosis
The prognosis for cutaneous listeriosis is generally good if the infection is treated promptly and appropriately. Without treatment, however, the infection can spread and become life-threatening.
