Cutaneous diphtheria is a bacterial infection caused by Corynebacterium diphtheriae. It primarily affects the skin and is characterized by the presence of skin ulcers. This article provides a comprehensive overview of cutaneous diphtheria, including its causes, symptoms, diagnosis, treatment, and prevention.

Causes

Cutaneous diphtheria is caused by the bacterium Corynebacterium diphtheriae. The bacteria produce a toxin that can harm human tissues. The infection is usually contracted through direct contact with wounds or sores on an infected person.

Symptoms

The primary symptom of cutaneous diphtheria is the presence of skin ulcers, usually on the legs, feet, or hands. These ulcers are often covered by a grayish membrane. Other symptoms may include mild fever, redness, and swelling around the infected area.

Diagnosis

Diagnosis of cutaneous diphtheria is typically made through a combination of clinical examination and laboratory testing. The bacteria can be identified under a microscope or through a culture test.

Treatment

Treatment for cutaneous diphtheria usually involves antibiotics to kill the bacteria and antitoxin to neutralize the toxin produced by the bacteria. In severe cases, surgical debridement of the wound may be necessary.

Prevention

Prevention of cutaneous diphtheria primarily involves good hygiene practices and vaccination. The diphtheria vaccine is highly effective in preventing the disease.
