cutaneous diphtheria

Cutaneous diphtheria is an infection of the skin caused by Corynebacterium diphtheriae and is typically a mild form of diphtheria. It presents as a chronic, shallow ulcer that is sometimes bordered or followed by a bulla. This condition is primarily seen in individuals exposed to the bacterium and is not associated with any known genetic factors. Although precise prevalence data is not available, the condition remains an uncommon clinical entity that is managed through prompt medical care.

Individuals with cutaneous diphtheria typically develop a shallow skin ulcer that may have an inflamed or raised border, and in some cases, a fluid-filled bulla can form. The lesion is often chronic and may fail to heal normally, which can alert clinicians to the possibility of an underlying diphtheria infection. Not all individuals experience the same severity of skin findings, and the appearance of the lesion may vary from person to person.

Cutaneous diphtheria is caused by an infection with the bacterium Corynebacterium diphtheriae. Unlike genetically inherited conditions, this disease arises due to exposure to bacterial toxins that affect the skin. There is no inherited component associated with this condition, and family history does not play a role in its occurrence.

Currently, management of cutaneous diphtheria focuses on supportive care and symptom management. Although there are no treatments specifically approved for this condition, many individuals benefit from antibiotic therapy to eliminate the underlying bacterial infection, along with proper wound care to promote healing. Treatment is individualized and typically involves consultation with healthcare professionals experienced in managing infectious diseases. Patients should discuss treatment options with their healthcare team to determine the most appropriate approach.

With timely and appropriate treatment, cutaneous diphtheria generally has a favorable outlook. However, the clinical course can vary, and not all patients experience the same degree of symptoms or complications. Outcomes described in medical literature continue to evolve as standards of care improve, and individual experiences differ based on various factors. Families often find it helpful to connect with infectious disease specialists and other healthcare providers for ongoing guidance and support.
