The soft palate (also known as the velum, palatal velum, or muscular palate) is, in mammals, the soft tissue constituting the back of the roof of the mouth. The soft palate is part of the palate of the mouth; the other part is the hard palate .
Bohn’s nodules, described by Heinrich Bohn in 1886 as "mucous gland cysts", are distributed over the junction of the hard and soft palate. They are derived from minor salivary glands. They are found at the junction of the hard and soft palate, and along lingual and buccal parts of the dental ridges, away from the midline. These nodules are 1 ...
Inflammatory papillary hyperplasia (IPH) is a benign lesion of the oral mucosa which is characterized by the growth of one or more nodular lesions, measuring about 2mm or less. [4] [5] The lesion almost exclusively involves the hard palate, and in rare instances, it also has been seen on the mandible. The lesion is mostly asymptomatic and color ...
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.
The lesion is suspicious because of the presence of nodules Nodular leukoplakia in right commissure. Biopsy showed severe dysplasia Biopsy showed severe dysplasia The annual malignant transformation rate of leukoplakia rarely exceeds 1%, [ 9 ] i.e. the vast majority of oral leukoplakia lesions will remain benign.

The palatine tonsils are located in the isthmus of the fauces, between the palatoglossal arch and the palatopharyngeal arch of the soft palate.. The palatine tonsil is one of the mucosa-associated lymphoid tissues (MALT), located at the entrance to the upper respiratory and gastrointestinal tracts to protect the body from the entry of exogenous material through mucosal sites.
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.
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.
