RESUMEN
We observed a case of Aeromonas genus infection in soft tissue caused by an underwater trauma. The patient was a 67-year-old male. His chief complaint was the left cruralgia, and his medical history was unremarkable. The clinical history was that he fell into a rice field while riding a bicycle on July 22, 2005, and suffered a blow to the left eras. On the same day, he was emergently referred to our hospital. He was diagnosed with a left eras bruise; after his wound was washed and sewed up, antibiotics were administered. When he visited our hospital again on July 24, he was hospitalized because of aggravated infection. His wound was urgently washed, drained, and debrided.<br>Aeromonas genus was detected in a bacterial culture. The wound was opened and debrided on August 5 because skin necrosis appeared on the sewed portion of the wound due to continued infection. As the infection receded, granulation was promoted by bFGF and the patient was declared healed on September 22. The Aeromonas genus is a gram-negative, rod-shaped genus of bacteria that lives underwater, and a fatal course due to infection with it is possible even from a mild trauma. Although few cases of Aeromonas infection in soft tissue during spa treatment have been reported, springs could always be polluted by them because they are environmental bacteria. It is important to suspect bacterial infection in the case of an underwater trauma and administer appropriate treatment. In addition, it is necessary to consider the possibility of contamination of spa water with bacteria when we receive spa treatment. We want to enlighten spa operators and users about preventing infection in the future.
