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.
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.
Congenital lesions can resolve spontaneously (involute) but those that develop later usually continue to slowly grow. They are usually dark red-purple or blue, soft, sometimes fluctuant and painless. They commonly blanch on pressure. Usually solitary, they can occur as part of syndromes such as Sturge–Weber syndrome affecting the trigeminal ...
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.

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 ...
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 ...
A squamous cell papilloma is a generally benign papilloma that arises from the stratified squamous epithelium of the skin, lip, oral cavity, tongue, pharynx, larynx, esophagus, cervix, vagina or anal canal.
