What type of stomatitis is characterized by necrotic ulceration of the oral mucous membranes?

Vincent's stomatitis is characterized by necrotic ulceration of the oral mucous membranes, which is primarily due to a mixed bacterial infection, often involving organisms such as Fusobacterium and Borrelia. This condition typically manifests as painful ulcers covered by a greyish pseudomembrane and can be associated with systemic symptoms like fever and lymphadenopathy. The presence of necrosis distinguishes it from other types of stomatitis.

Aphthous stomatitis, on the other hand, presents as painful, shallow ulcers in the oral mucosa but does not typically involve necrotic tissue. Allergic stomatitis is a response to allergens that leads to inflammation and irritation, while herpetic stomatitis is caused by the herpes simplex virus, resulting in vesicular lesions rather than necrotic ulcers. Thus, the unique characteristic of necrotic ulceration in Vincent's stomatitis makes it the appropriate choice in this context.
