Cancrum oris in developed countries.

Cancrum oris (or noma) is a rapidly progressive disease characterized by destructive necrosis of oral tissues and underlying bone. It is part of a multistage condition and may represent the outcome of untreated necrotizing stomatitis. Necrotising stomatitis and cancrum oris predominantly affect children in developing countries, especially in Africa. Only few cases have been reported in developed countries, and were associated with debilitating diseases and disorders of the immune system. We report a case of noma in an elderly immunosuppressed Italian patient in whom necrosis caused an external buccal communication. This case stresses the importance of an early identification and prompt management of the necrotic condition, in order to avoid diffusion of the destructive process within the oro-facial tissues.
