Necrotizing cellulitis caused by Legionella micdadei.

Legionella micdadei is primarily considered a pathogen of the pulmonary tract of immunocompromised patients, the majority of whom have been renal transplant recipients. We report the case of a necrotizing soft tissue infection in a cadaveric renal transplant recipient resulting in amputation of the left arm. Only one other extrathoracic bacteriologically documented L. micdadei infection has been reported in the literature.
