Subcutaneous nodules with pseudomonas septicaemia in an immunocompetent patient.

Pseudomonas septicaemia presenting with subcutaneous nodules, though rare, is well described in immunocompromized populations. It is, however, very uncommon in immunocompetent patients. We describe a case of a 42-year-old woman who presented with community-acquired. Pseudomonas aeruginosa septicaemia and subcutaneous nodules. No precipitating cause or immune dysfunction was found. She was successfully treated with appropriate antibiotics, respiratory and cardiovascular support in the Intensive Care Unit. The difficulty in eradicating the organism from the skin lesion and the need for investigating the immune function of septicaemia patients are discussed.
