Irritation fibromas are common benign tumors that are asymptomatic and resemble scarring. They are caused by prolonged irritation in the mouth, such as cheek or lip biting, rubbing from teeth, and dental prostheses. The fibromas are firm, smooth, and fibrous with a color usually identical to the oral mucosa but can be paler. If wounded, it may ...
The cemento-ossifying fibroma is hard and fibrous, most frequently seen in the jaw or mouth, sometimes in connection with a fracture or another type of injury. Other fibromas: chondromyxoid fibroma , desmoplasmic fibroma , nonossifying fibroma , ossifying fibroma , nuchal fibroma , collagenous fibroma , fibroma of tendon sheath , perifollicular ...
Warthin's tumor, also known as papillary cystadenoma lymphomatosum, is a benign cystic tumor of the salivary glands containing abundant lymphocytes and germinal centers (lymph node-like stroma). It is named for pathologist Aldred Scott Warthin , who described two cases in 1929.
Pleomorphic adenoma (or benign mixed tumor) is a common benign salivary gland neoplasm characterised by neoplastic proliferation of epithelial (ductal) cells along with myoepithelial components, having a malignant potentiality. It is the most common type of salivary gland tumor and the most common tumor of the parotid gland.
Little is known about the total incidence of salivary gland tumours as most benign tumours go unrecorded in national cancer registries. [2] The majority of salivary tumours are benign (65-70%). [3] Within the parotid gland 75 - 80% of tumours are benign. Around 50% of the tumours found in the submandibular glands are benign.
However, a benign tumor is not benign in the usual sense; the name merely specifies that it is not "malignant", i.e. cancerous. While benign tumors usually do not pose a serious health risk, they can be harmful or fatal. [2] Many types of benign tumors have the potential to become cancerous through a process known as tumor progression. For this ...
Squamous cell papilloma of the mouth or throat is generally diagnosed in people between the ages of 30 and 50, [1] and is normally found on the inside of the cheek, on the tongue, or inside of lips. Oral papillomas are usually painless, and not treated unless they interfere with eating or are causing pain. [ 1 ]
Most tumors are small, up to 2 cm (given the confines of the tongue, a larger mass would cause significant clinical problems).
