Clostridium septicum gas gangrene in the orbit: a case report.

Our report presents a case of Clostridium septicum gas gangrene in an unusual, orbital localization. The predisposing factors are typical: colon tumour and lymphatic malignancy. Most probably bacteria from the intestinal flora entered the bloodstream through the compromised intestinal wall and settled in the orbit resulting in the development of an abscess containing gas. At the site of the gas gangrene, an indolent B cell lymphoma was present. After surgery and antibiotic treatment, the patient healed from the C. septicum infection; but subsequently died as a consequence of the tumour.
