Noma (from Greek numein: to devour) also known as cancrum oris or gangrenous stomatitis, is a gangrenous disease leading to tissue destruction of the face, especially the mouth and cheek. The mucous membranes of the mouth develop ulcers, and rapid, painless tissue degeneration ensues, which can degrade tissues of the bones in the face http://health.allrefer.com/health/noma-info.html. The disease degrades the faces of children within days.
