'''Bullous impetigo''' is a [[bacterial skin infection]] that primarily affects infants and young children, although it can occur in individuals of any age. It is characterized by the formation of large, fluid-filled blisters, or bullae, on the skin.

A bacterial skin infection characterized by large blisters
Bullous impetigo is a bacterial skin infection that primarily affects infants and young children, although it can occur in individuals of any age. It is characterized by the formation of large, fluid-filled blisters, or bullae, on the skin. This condition is a form of impetigo, which is a common and highly contagious skin infection.
Etiology[edit]
Bullous impetigo is caused by the bacterium Staphylococcus aureus. This bacterium produces a toxin that causes the skin to separate, leading to the formation of blisters. The infection is typically spread through direct contact with the lesions or through contact with contaminated objects.
Clinical Presentation[edit]
The hallmark of bullous impetigo is the appearance of large, fluid-filled blisters on the skin. These blisters are usually painless but can be itchy. The blisters may rupture, leaving a yellow crust. The lesions are most commonly found on the face, arms, legs, and trunk.
Diagnosis[edit]
Diagnosis of bullous impetigo is primarily clinical, based on the characteristic appearance of the lesions. A bacterial culture of the fluid from the blisters can be performed to confirm the presence of Staphylococcus aureus.
Treatment[edit]
Treatment of bullous impetigo involves the use of antibiotics. Topical antibiotics, such as mupirocin, are often effective for localized infections. In more extensive cases, oral antibiotics such as cephalexin or dicloxacillin may be prescribed. It is important to maintain good hygiene and avoid scratching the lesions to prevent the spread of infection.
Complications[edit]
Complications of bullous impetigo are rare but can include cellulitis, lymphangitis, and sepsis. Prompt treatment with antibiotics usually prevents these complications.
Prevention[edit]
Preventive measures include maintaining good personal hygiene, avoiding close contact with infected individuals, and keeping wounds clean and covered. In settings such as schools and daycare centers, it is important to disinfect surfaces and objects that may be contaminated.
