impetigo

 [im″pĕ-ti´go]
a contagious skin disorder, caused by streptococci, staphylococci, or a combination of organisms and marked by vesicles or bullae that become pustular, rupture, and form yellow crusts; called also impetigo contagiosa or impetigo vulgaris. Impetigo usually occurs in children, especially very young infants because of their low resistance, and is spread by direct contact with the moist discharges of the lesions. If not properly treated, it can be serious or even fatal to newborn infants. Isolation of the patient is recommended if patient hygiene is poor or the patient is a newborn in a hospital. Gowns and gloves are worn if soiling is likely. Impetigo is a particular problem for hospital patients, who may become infected by infected hospital staff. Treatment may consist of local applications of an antibiotic ointment, keeping the lesions and surrounding skin clean, and exposing the lesions to air to encourage drying. Systemic antibiotics are often recommended. (See Atlas 2, Part G).
bullous impetigo a highly contagious type of impetigo, caused by Staphylococcus aureus and characterized by large pustules surrounded by reddened areas; transmission is by direct contact, by fomites, or by autoinoculation causing secondary infections in areas of the body not originally affected.

bullous impetigo

Bullous impetigo may occur after minor skin injury, such as an insect bite, abrasion, or dermatitis.
Lymphadenopathy is rare in bullous impetigo but common in nonbullous impetigo.
The differential diagnosis for bullous impetigo is broad, and may include allergic contact dermatitis, herpes simplex, herpes zoster, pemphigus foliaceus, bullous pemphigoid, pemphigus vulgaris, and (in this case specifically) erythema migrans.
Bullous impetigo is a variant of impetigo that produces exfoliative or epidermolytic toxins (ETA and ETB) in response to a staphylococcal infection.
A patient with bullous impetigo typically presents with a history of vesicular lesions that progress to flaccid bullae with little/no surrounding erythema.
The differential diagnosis of bullous impetigo includes contact dermatitis, bullous insect bites, thermal burns, pemphigus vulgaris, bullous pemphigoid, erythema multiforme, and dermatitis herpetiformis.
Bullous impetigo appears with scattered lesions of erythema and macules, progressing to thin roofed bullae and subsequently to "honey-crusted" lesions.
Infections in newborns that may present as bullae, erosions, or ulcers include bullous impetigo and staphylococcal scalded skin syndrome.
