What is a notable complication of untreated severe impetigo?

In the context of untreated severe impetigo, a significant complication that can arise is scarring. Impetigo is a common and highly contagious skin infection often caused by Staphylococcus aureus or Streptococcus pyogenes, resulting in the formation of pustules and honey-colored crusts on the skin. If the infection is not adequately treated, it can lead to deeper tissue involvement and persistent inflammation, which ultimately can compromise the integrity of the skin.

When the skin is damaged due to extensive infection, the healing process may not restore the skin to its original state, resulting in scarring. Scarring can occur after the lesions heal, especially in severe cases where the infection leads to deeper tissue irritation or destruction. It is essential to manage and treat impetigo promptly to prevent such long-term complications. While other complications like cutaneous abscesses or septicemia can occur, scarring is a more direct and common consequence of untreated impetigo.
