Ecthyma Gangrenosum: Escherichia coli or Pseudomonas aeruginosa?

Background: Ecthyma gangrenosum (EG) are necrotic lesions that develop in the context of Pseudomonas aeruginosa bacteremia. Isolated reports describe EG in the setting of non-Pseudomonal infections. In a patient with EG, initial blood cultures showed Escherichia coli, and almost occulted P. aeruginosa bacteremia. Based on the clinical picture we suspected preponderant P. aeruginosa bacteremia, ...

Ecthyma gangrenosum in Saudi Arabia.

We report a diagnosis of ecthyma gangrenosum EG in 4 females of mean age 54.8 range 43-64 years, within 10 months. Severe drug reaction treated with high dose systemic corticosteroids in patient one, acute myelocytic leukemia treated with high dose dexamethasone, and multiple broad-spectrum antibiotics in patient 2 preceded the onset of EG. Patients 3 and 4 had vasculitic purpura and hemodialys...

Ecthyma Gangrenosum: A Rare Cutaneous Manifestation Caused by Stenotrophomonas maltophilia in a Leukemic Patient.

Ecthyma gangrenosum (EG) is a well-recognized cutaneous infection that most commonly affects immunocompromised patients. It typically occurs on the extremities, or in gluteal and perineal regions. Although Pseudomonas aeruginosa is the most well-known pathogen causing EG, other organisms have been reported to cause EG. Herein we report a rare case of ecthyma gangrenosum presenting as aggressive...
