Inflammatory papillary hyperplasia almost exclusively involves the hard palate, specifically the vault of the palate. Extension of the lesion to the mucosa of the residual ridges have also been observed. 11% to 13.9% of patients who wear maxillary complete dentures with complete palatal coverage has been reported to have IPH.

Oral cancer affects the areas of the mouth, including the inner lip, tongue, floor of the mouth, gums, and hard palate. Cancers of the mouth are strongly associated with tobacco use, especially the use of chewing tobacco or dipping tobacco , as well as heavy alcohol use.
Granular cell tumors can affect all parts of the body; however, the head and neck areas are affected 45% to 65% of the time. Of the head and neck cases 70% of lesions are located intraorally (tongue, oral mucosa, hard palate). The next most common location that lesions are found in the head and neck area is the larynx (10%). [5]
Site – gingiva, buccal mucosa, alveolar mucosa, hard palate, floor of the mouth, larynx, oesophagus, penis, vagina, scrotum. Clinical presentation: It is a slow growing, diffuse, exophytic lesion usually covered by leukoplakic patches. Invasive lesions quickly invade bones.
Leukoplakia located on the floor of the mouth, the posterior and lateral tongue, and the retromolar areas (the region behind the wisdom teeth) have higher risk, whereas white patches in areas such as the top surface of the tongue and the hard palate do not have significant risk. [3]
Acinic cell carcinoma is a malignant tumor representing 2% of all salivary tumors. 90% of the time found in the parotid gland, 10% intraorally on buccal mucosa or palate. The disease presents as a slow growing mass, associated with pain or tenderness in 50% of the cases. Often appears pseudoencapsulated.
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.
It is most commonly found in the palate. [2] The name of the tumor derives from the fact that: It has a varied microscopic architectural appearance, i.e. it is polymorphous. It is non-aggressive when compared to other oral cavity tumors, i.e. it is a low-grade tumor. [1] It forms glands, i.e. it is an adenocarcinoma.
