Case Reports

Abstract: Of the 2 species of Chromobacterium, Chromobacterium violaceum has been rarely implicated in human disease. It is a bacterium of low virulence causing occasional localized infection and sepsis. We report a case of C. violaceum infection of pancreatic pseudocyst. The patient was treated by cystojejunostomy with Roux-en-Y jejunal loop and antimicrobial therapy with ciprofloxacin and amikacin. As sepsis due to this organism is associated with high mortality, empiric therapy with fluoroquinolones and aminoglycosides is recommended, along with proper surgical management.

C. violaceum is an extremely rare cause of pancreatic pseudocyst infection. Given the fact that sepsis due to this organism is associated with high mortality, initial empiric therapy with drugs such as fluoroquinolones and aminoglycosides is recommended, along with proper surgical management to bring about complete resolution. The prognosis should be guarded even when the infection appears to be localized, because of its propensity to disseminate.
