Objective: This study aimed to estimate the prevalence of lichenoid reactions to Anti Hyperglycemic Agents. Materials and Methods: In this cross-sectional descriptive and analytic study, we examined the oral mucosa of 411 patients at the age of 29 to 85 in 3 groups who consumed various antihyperglycemic agents. Results: In overall, 31 patients had lichenoid reactions (12 patients taking glibe...

lichenoid reactions represent a family of lesions with different etiologic factors and a common clinical and histologic appearance. lichen planus is included with lichenoid reactions and is a relatively common chronic mucocutaneous disorder. the most important complication of lichenoid reactions is the possibility of malignant transformation. that is why it has been considered a precancerous co...

Oral lichenoid reactions represent a common end point in response to extrinsic agents (drugs, allergens), altered self-antigens, or superantigens. Oral lichen planus, a common and under-recognized inflammatory disorder, shares many clinical and histopathological features with oral lichenoid drug reaction and oral lichenoid contact reaction. Clinical presentation can vary from asymptomatic white...

The terms oral lichenoid reactions or oral lichenoid lesions refer to lesions histologically and clinically similar to oral lichen planus, though with the particularity that in these cases the underlying cause is identifiable. In addition, these lesions are described according to the causal factor involved, including alterations resulting from direct contact with dental restoration materials, d...

Oral lichenoid reactions are disease conditions with definite identifiable aetiology. It can occur either due to intake of drug i.e. lichenoid drug eruptions or due to contact with some potential irritants which majority of times are dental materials. Some other allergens including certain food items are also reported. Some systemic conditions such as chronic liver disease, hepatitis C virus in...

Sir, Cutaneous drug reactions have a wide variety of clinical features. Lichenoid drug eruptions (LDE) are rare and it may be difficult to differentiate them from idiopathic lichen planus (1, 2). Gold, quinine, quinidine and penicillamine are well-known inducers of such eruptions (1, 2), but there are only a few reports of lichenoid eruption induced by 3-hydroxy-3-methyl-glutaryl coenzyme A (HM...

Lichenoid drug reactions are more common in skin, but they may also occur in the oral mucosa. It is difficult to diagnose these lesions due to their clinical similarity to the idiopathic oral lichen planus lesions. The present article reports a case of lichenoid reaction in oral mucosa associated to the use of carbamazepine, emphasizing the diagnostic process.
