The Head and Neck
Published in E. George Elias, CRC Handbook of Surgical Oncology, 2020
The hard palate carcinomas are rare with an incidence of 0.5% of oral cavity cancers. The lymphatic drainage is behind the dental arch to the retropharyngeal, internal jugular, and submandibular lymph nodes. Primary tumors of the hard palate can be salivary gland in origin such as cylindromas, epidermoid carcinomas, or bone tumors. These can easily invade the maxillary sinus and/or the upper gingiva. Such tumors should be differentiated from other conditions such as torus palatinus, papillomata, dentigerous cysts, and very rarely now the syphilic gumma.

This is a completely benign bone lump in the midline of the hard palate. Another favoured site is along the lingual plate of the mandible. Its grows slowly and is usually spherical or oval shaped (Fig. 11.34). The overlying mucosa has a normal appearance, but if the lump is large the mucosa is stretched over the bone surface and tears easily. The exposed dense bone can be very painful and slow to heal. A torus palatinus may interfere with the fitting of a denture.
Images in medicine: torus palatinus
Published in Journal of Community Hospital Internal Medicine Perspectives, 2019
Oral tori (Figure 1) are common exostoses with a prevalence of about 20–30% in the general USA population. [1] Torus palatinus is more common in women and in people of Asian and Inuit ancestry. [2,3] The pathogenesis is not well-understood, and appears to be a complex interplay of occlusive (biting) forces, genetics, and environmental factors. [3–5] Medical conditions associated with bone disruption, e.g., hyperparathyroidism (of any type), have also been found to be associated with torus development[6]. This slowly growing benign lesion can take decades to grow into a noticeable size and patients generally do not report them as they are asymptomatic. [4] In the cases in which a torus interferes with dental work, such as fitting dentures or prosthetic devices, or in the process of mastication, surgical removal might be warranted. [3–5]
