Treatment

Medical Care

Ecthyma gangrenosum (EG) requires prompt diagnosis and treatment with appropriately selected antibiotics for the underlying etiology. If the lesion fails to respond to antimicrobials, surgical debridement of the spreading, necrotic lesion may be required. [20, 21] The presence of EG should alert the physician to the likelihood of pseudomonal bacteremia, and the early implementation of antimicrobial agents is necessary to reduce the high mortality associated with pseudomonal sepsis.

Treatment of EG requires the use of antipseudomonal penicillins, aminoglycosides, fluoroquinolones, third-generation cephalosporins, or aztreonam. While awaiting results, an antipseudomonal penicillin (piperacillin) should be used in conjunction with an aminoglycoside (gentamicin). Further adjustment of antibiotics may be required after sensitivity results are known. Granulocyte-macrophage colony-stimulating factor may also be administered to patients with severe leukopenia and ecthyma gangrenosum to aid in recovery. [22]

Systemic antifungal coverage should be considered if fungemia is suspected, including coverage against Aspergillus, Candida, and Mucor species with azole agents (eg, voriconazole, fluconazole) and/or amphotericin B if appropriate.

If empiric antimicrobial and antifungal therapy is used, it must be comprehensive and should cover all likely pathogens in the context of the clinical setting. Antibiotic selection should be guided by blood culture sensitivity results whenever feasible.
