Lichenoid lesions


Lichenoid lesions include a broad group of oral mucosa lesions which share clinical characteristics and histological criteria with Oral Lichen Planus (OLP); although the infiltrate is mixed (plasma cells, eosinophils, and neutrophils)The etiology of OLL is usually identifiable and are indicative of disease or different, localised conditions.  The best known lichenoid lesions (LL) are:-...

Amalgam tatoo


An amalgam tattoo is a pigmentation of the mucosa, situated near to amalgam restoration (also if the latter is not more present). On degrading, the amalgam products are deposited between the keratinocyte tissue, thereby producing an abnormal, greyish colouration of the tissue. This is totally asymptomatic, only requiring treatment for aesthetic reasons.

Leiomyoma


A leiomyoma is a benign tumour which originates in smooth muscle cells. It occurs mainly in the uterus, the stomach and the oesophagus. In the oral cavity, a leiomyoma lesion is rare, presenting clinically as a sub-mucosal mass, which is asymptomatic and generally slow-growing. A leiomyoma can occur at any age, and most...

Kaposi’s sarcoma


Kaposi’s sarcoma is a neoplasm which occurs only in patients whose immune system has been compromised, particularly HIV patients where it is often the first symptom of AIDS. However, it can appear in transplant patients and there is also an endemic form in sub-Saharan Africa which is correlated to an HHV-8 infection. Kaposi’s...

Necrotizing sialometaplasia


Necrotizing sialometaplasia is a benign pathology which generally occurs on the palate. It is probable that this pathology is caused by ischaemia of a salivary gland, following local trauma. Clinically, necrotizing sialometaplasia is characterised by swelling which is covered by erythematous mucous which subsequently ulcerates, presenting a yellow-grey base; it is moderately painful. A...

Oral Lichen Planus


Oral Lichen Planus is a chronic, inflammatory pathology of unknown aetiology and autoimmune pathogenesis; it is more common in women between the ages of 50 and 60 years of age. Clinically, various types are recognised, being reduced to two categories, distinguishable by their white and/or red colour.When the lesions are white, they can...

Lymphangioma


A lymphangioma is a proliferative, benign neoformation of a network of vessels, originating in a proliferation of the epithelium of the lymphatic system (lymphangioma). It can present at birth or during the first months of life (as a congenital variant and/or manifestation of an oral, systemic pathology, eg. Sturge–Weber syndrome, Maffucci syndrome,...
