Successfully Treated Upper-Extremity Necrotizing Fasciitis Caused by Photobacterium damselae.

Necrotizing fasciitis is a soft-tissue infection associated with significant morbidity and mortality. The bacteria most associated with necrotizing fasciitis include Streptococcus pyogenes (group A), Clostridium species, Streptococcus species, and Staphylococcus species. Photobacterium damselae (P. damselae), formerly known as Vibrio damselae, is a halophilic, gram-negative bacillus known to infect marine organisms in warm coastal waters. Necrotizing fasciitis associated with P. damselae has been reported to have higher rates of serious complications and mortality because of an atypical presentation and a rapidly progressive course. This report presents a case of successfully treated P. damselae necrotizing fasciitis of the upper extremity and the nuances of management that led to a favorable outcome in which the patient was discharged for home without complications.
