[1] In people who wear dentures 24 hours a day, its incidence is around 20%. Inflammatory papillary hyperplasia almost exclusively involves the hard palate, specifically the vault of the palate.
Hay–Wells syndrome (AEC syndrome, ankyloblepharon filiforme adnatum–ectodermal dysplasia–cleft palate syndrome, ankyloblepharon–ectodermal defects–cleft lip and palate syndrome, ankyloblepharon–ectodermal dysplasia–clefting syndrome) Hereditary sclerosing poikiloderma Keratosis pilaris; Heterochromia iridum
Initially a vascular lesion is usually noted on the skin which can be firm and hard (indurated). Areas of tiny red dots (petechiae) can appear around the lesion or on other parts of the body. If the vascular lesion is internal, these petechiae and bruising can be seen on the skin. Bruising and spontaneous bleeding can also occur.
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.

This is followed by a thorough clinical investigation including extra-oral and intra-oral hard and soft tissues.
