Ecthyma gangrenosum-like lesions in a healthy child after infection treated with antibiotics.

Ecthyma gangrenosum is a cutaneous infection associated most commonly with pseudomonal sepsis in the immunocompromised patient. We describe a previously healthy 4-year-old boy who developed ecthyma gangrenosum-like lesions secondary to antibiotic treatment for possible streptococcal infection. The skin, ears, and extremities were involved. This presentation emphasizes the importance of awareness of the rare complication of ecthyma gangrenosum-like lesions associated with non-Pseudomonas bacterial infection treated with antibiotics, even in a previously healthy child.
