Ecthyma gangrenosum due to Pseudomonas aeruginosa without septicemia in a neutropenic patient.

Introduction. - Ecthyma gangrenosum is a rare skin infection caused by gram negative bacteria. It involves immunocompromised patients, especially neut ropenic patients, and can be easily diagnosed. Exegesis. - We report a case of ecthyma gangrenosum without septicemia due to Pseudomonas aeruginosa in a myelodysplastic patient with severe neutrope nia. Granulocyte growth factors adjunction was necessary in combination to antibiotics to obtain complete healing. Conclusion. - In neutropenic patient, ecthyma gangrenosum due to Pseudomona s aeruginosa should be rapidly diagnosed to avoid septicemic complications. In the case of antibiotic treatment failure, granulocyte growth factors ma y be added. Frequent Pseudomonas aeruginosa infections justify bacteriologi c survey to look for hospital contamination.
