Necrotizing sialometaplasia (NS) is a benign, ulcerative lesion, usually located towards the back of the hard palate. It is thought to be caused by ischemic necrosis (death of tissue due to lack of blood supply) of minor salivary glands in response to trauma. Often painless, the condition is self-limiting and should heal in 6–10 weeks.
These lesions most often appear on the tonsillar pillars (adjacent to the tonsils), but also on the soft palate, tonsils, uvula, or tongue. [5] A small number of lesions (usually two to six) form in the back area of the mouth, particularly the soft palate or tonsillar pillars.

In herpangina, ulcers are usually isolated to the soft palate and anterior pillar of the mouth. [15] In herpetic gingivostomatitis, lesions can be found in these locations, but they are almost always accompanied by ulcerations on the gums, lips, tongue or buccal mucosa and/or by hyperemia, hypertrophy or hemorrhage of the gums.

flaccid paralysis, [1] such as soft palate weakness (examined by asking the patient to say aah). [1] muscle atrophy, [1] such as tongue atrophy with fasciculations. nasal speech lacking in modulation and difficulty with all consonants. drooling of saliva. [1] normal or absent jaw jerk. reduced or absent gag reflex. [1]
The cause is usually pressure from the flange of a denture which causes chronic irritation and a hyperplastic response in the soft tissues. [6] Women during pregnancy can also present with an epulis, which will resolve after birth. Fibroepithelial polyps, pedunculated lesions of the palate beneath an upper denture, are associated with this ...
Oropharyngeal cancer, [1] [2] [3] also known as oropharyngeal squamous cell carcinoma and tonsil cancer, [1] is a disease in which abnormal cells with the potential to both grow locally and spread to other parts of the body are found in the oral cavity, in the tissue of the part of the throat that includes the base of the tongue, the tonsils, the soft palate, and the walls of the pharynx.
WSN presents most commonly in the mouth, as thickened, bilateral, symmetrical white plaques with a spongy, corrugated or velvety texture. Lesions are typically present on the buccal mucosa, but may also affect the labial mucosa, alveolar ridge, floor of the mouth, ventral surface of the tongue, lip vermillion or soft palate.
