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

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,...

Drug-related overgrowth


A drug-related gingival overgrowth is a hyperplasia of the gingival tissue, associated with specific classes of drugs. These include immuno-suppressants (e.g. cyclosporin), calcium-antagonists (e.g. nifedipine), and anti-epileptic drugs (e.g. phenytoin); they trigger an anomalous stimulation of fibroblasts, thereby causing uncontrolled replication. The hyperplasia presents as a gradual swelling, which is generally widespread throughout...

Behҫet’s syndrome

Clinically it is characterised by a asymptomatic, bilateral or unilateral swelling of the major salivary glands. The causes of sialadenitis are: diabetes, anorexia/bulimia and alcohol abuse. Moreover, the clinical picture can be described within the realm...
