Necrotizing Ulcerative Gingivitis (C0017575)

Definition (NCI) A bacterial infectious process affecting the gums. It is characterized by the development of necrotic, ulcerated, and painful lesions with creation of pseudomembranes extending along the gingival margins.
Definition (MSH) An acute or chronic GINGIVITIS characterized by redness and swelling, NECROSIS extending from the interdental papillae along the gingival margins, PAIN; HEMORRHAGE, necrotic odor, and often a pseudomembrane. The condition may extend to the ORAL MUCOSA; TONGUE; PALATE; or PHARYNX. The etiology is somewhat unclear, but may involve a complex of FUSOBACTERIUM NUCLEATUM along with spirochetes BORRELIA or TREPONEMA.

Noma (C0028271)

Definition (NCI) Gangrene of the mucous membranes of the mouth leading to ulcers and destruction of the soft tissues of the face and bones. It usually occurs in malnourished children in areas of poor sanitation and immunocompromised patients.
Definition (MSH) A severe gangrenous process occurring predominantly in debilitated and malnourished children, especially in underdeveloped countries. It typically begins as a small vesicle or ulcer on the gingiva that rapidly becomes necrotic and spreads to produce extensive destruction of the buccal and labial mucosa and tissues of the face, which may result in severe disfigurement and even death. Various bacteria have been implicated in the etiology. (Dorland, 27th ed)
