cutaneous diphtheria

Cutaneous diphtheria is a form of the infectious disease diphtheria that affects the skin rather than the respiratory tract. It typically occurs following a wound or sore. The disease itself is caused by the bacterium Corynebacterium diphtheriae.1

Diphtheria is characterized by the formation of a thick, leathery, grayish pseudomembrane composed of bacteria, dead cells, and fibrin. This membrane can adhere to the site of infection. While the primary lesion is usually in the upper respiratory tract, the toxin produced by the bacteria can spread throughout the body, potentially damaging the heart and nervous system.1

Treatment involves administering diphtheria antitoxin, which neutralizes the toxin, and antibiotics to eliminate the bacteria. Prevention is achieved through immunization with diphtheria toxoid, often administered as part of routine childhood vaccinations.12
