[Locoregional polymorphous Pseudomonas aeruginosa skin infection.]
Résumé
A 72-year-old diabetic woman was referred with a painful chronic leg ulcer associated with venous and arterial insufficiency. She then developed a polymorphous skin infection due to Pseudomonas aeruginosa, with ecthyma gangrenosum, subcutaneous abscess and panniculitis of the homolateral inferior limb, without general sepsis. Although P. aeruginosa infection may induce polymorphous skin lesions, they are most often observed in immunocompromised patients following septicaemia.
