Impetigo, Pediatric

Streptococcal impetigo. The lower extremities exhibit numerous erythematous papules, with central ulceration and the formation of crusts.

FIG. 11.30. Bullous impetigo. This 6-year-old girl developed widespread impetigo after a visit to Central America. Lesions appear crusted, scabbed, bullous, or covered with calamine lotion. Staphylococcus aureus causes almost all cases of bullous impetigo.

FIG. 11.31. Impetigo. This child has primarily crusted and scabbed as opposed to bullous lesions. Both group A streptococci and staphylococci may produce lesions with this morphology.

FIG. 11.32. Facial impetigo in an infant. This infant has a single patch of impetigo on her cheek. Because of the circular appearance of the lesion, it was thought to be a cigarette burn from child abuse on initial evaluation. Gram stain yielded abundant segmented neutrophils and Gram-positive cocci, followed by the isolation of Staphylococcus aureus in culture.
