ABSTRACT
Impetigo is a contagious superficial bacterial skin infection, predominantly affecting children. There are two types of impetigo: nonbullous and bullous. Bullous impetigo is caused by toxin-producing S. aureus. We present a case of bullous impetigo in a 6-year-old girl with skin lesions on the upper limbs.
Key words: Impetigo, Bullous, Nonbullous children
INTRODUCTION
Impetigo is a contagious superficial bacterial skin infection, predominantly affecting children [1].
There are two types of impetigo: nonbullous (i.e., impetigo contagiosa) and bullous. Nonbullous impetigo represents a host response to the infection, whereas a Staphylococcal toxin causes bullous impetigo and no host response is required to manifest clinical illness [2,3,4]. Bullous impetigo most commonly affects neonates but also can occur in older children and adults. Gupta observed bullosa impetigo in 12% among bacterial infections [5].
CASE REPORT
A 6-year-old girl with 5 days history of skin lesions on the upper limbs. Lesions in the type of blisters and erosions were located mainly in the area of the hand (Figs. 1a – 1c). It was associated with minimal itching and there were no constitutional symptoms.

The interview shows that the girl suffers from atopic dermatitis; xerosis on the skin has been found.
Other mucosal and nail examinations were within normal limits. This therapy was discontinued, fusic acid and emollient therapy were introduced. A final diagnosis of bullous impetigo was made. The lesions subsided completely after 7 days of treatment.
DISCUSSION
Bullous impetigo is caused by toxin-producing S. aureus and is a localized form of staphylococcal scalded skin syndrome. Superficial vesicles progress to rapidly enlarging, flaccid bullae with sharp margins and no surrounding erythema. Systemic symptoms are not common but may include weakness, fever, and diarrhea [2,5]. In differential diagnosis of bullous impetigo stands out: bullous erythema multiforme, bullous lupus erythematosus or bullous pemphigoid.Ana Maria Abreu Velez et al., insist that chronic bullous dermatosis of childhood (CBDC) is frequently misdiagnosed as bullous impetigo [6]. Therefore, it is important to make an appropriate diagnosis and monitor patients.
Consent
The examination of the patient was conducted according to the principles of the Declaration of Helsinki.
The authors certify that they have obtained all appropriate patient consent forms, in which the patients gave their consent for images and other clinical information to be included in the journal.
