Aeromonas hydrophila upper extremity infection.

A severe soft tissue infection of the upper extremity caused by Aeromonas hydrophila followed a water skiing injury in which a tow rope caused degloving of a portion of the skin and severe contusion to underlying muscle. Infection was established within 36 hours of the injury, accompanied by fever, leukocytosis, and a foul odor. Rapid clinical improvement occurred following radical debridement of all nonviable tissue and antibiotic therapy. In cases involving water contamination, Aeromonas hydrophila infection should be suspected with the onset of a rapidly developing infection with a febrile response. Rapid surgical intervention and treatment with an aminoglycoside or a third-generation cephalosporin antibiotic is the treatment of choice.
