Ecthyma gangrenosum secondary to Staphylococcus aureus in an infant with transient neutropenia.

Ecthyma gangrenosum is classically a cutaneous manifestation of a pseudomonal septicemia that presents in a patient with an immunodeficiency or hematologic malignancy. We describe a previously healthy 8-month-old girl who developed transient neutropenia and characteristic ecthyma gangrenosum lesions secondary to methicillin-resistant Staphylococcus aureus. This unique presentation of methicillin-resistant Staphylococcus aureus ecthyma gangrenosum emphasizes the importance of broad empiric coverage and early culturing for microorganism and susceptibilities in any patient presenting with ecthyma gangrenosum.
