Mucous retention cyst in maxillary sinus indicated by the asymmetrical blue lump to the right of the nose. The most common location to find a mucocele is the inner surface of the lower lip. It can also be found on the inner side of the cheek (known as the buccal mucosa), on the anterior ventral tongue, and the floor of the mouth.
Giant-cell fibromas are commonly located on the gingiva.The tongue is the second most common location, followed by the palate or buccal mucosa.Giant-cell fibromas are usually asymptomatic and appear as 0.5-1cm pedunculated or sessile lesions with a pebbly or bosselated surface.
Irritation fibroma is a type of fibroma that occurs on the mucosa of the oral cavity. [2] 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 lesions are located on the mucosa, usually bilaterally in the central part of the anterior buccal mucosa and along the occlusal plane level (the level at which the upper and lower teeth meet). Sometimes, the tongue or the labial mucosa (the inside lining of the lips) is affected by a similarly produced lesion, termed morsicatio linguarum ...
Alveolar mucosa, the lining between the buccal and labial mucosae. It is a brighter red, smooth, and shiny with many blood vessels, and is not connected to underlying tissue by rete pegs. [6] Buccal mucosa, the inside lining of the cheeks; part of the lining mucosa. Labial mucosa, the inside lining of the lips; part of the lining mucosa. [7]
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.
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.
Ulcerative colitis involves the colonic mucosa. Crohn's disease may produce inflammation in all layers in any part of the gastrointestinal tract and so can result in transmural fistulae. Invasion of tumours through the layers of the gastrointestinal wall is used in staging of tumour spread. This affects treatment and prognosis.
