noma

 [no´mah]
gangrenous processes of the mouth or genitalia. In the mouth (cancrum oris, gangrenous stomatitis), it begins as a small gingival ulcer and results in gangrenous necrosis of surrounding facial tissues. The condition on the genitalia is called erosive balanitis in males and erosive vulvitis in females.

no·ma

(nō'mă),
A gangrenous stomatitis, usually beginning in the mucous membrane of the corner of the mouth or cheek, and then progressing fairly rapidly to involve the entire thickness of the lips or cheek (or both), with conspicuous necrosis and complete sloughing of tissue; usually observed in poorly nourished children and debilitated adults, especially in poorer socioeconomic groups, and frequently preceded by another disease, for example, kala azar, dysentery, or scarlet fever. A similar process (n. pudendi, noma vulvae) also may involve the labia majora. Several organisms are usually found in the necrotic material, but fusiform bacilli, Borrelia organisms, staphylococci, and anaerobic streptococci are most frequently observed.
