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...

introduction: oral lichen planus (olp) is a common mucocutanous disorder with unknown etiology. while current data suggest that oral lichen planus is a cell-mediated autoimmune disease, it might be associated to s+100, cd+4 and cd+8 cells. because of differential diagnosis of olp and oral lichenoid lesion (oll) is usually difficult this study was designed to compare any probable immunohistochem...

Lichen planus is a dermatologic disease of unknown etiology characterized by keratotic plaques on the skin. Many patients also harbor white lesions of the oral mucosa. The literature contains numerous reports of lichen planus-like lesions evolving in conjunction with the administration of a variety of pharmacologic agents. It is difficult, if not impossible, to distinguish such lesions from one...

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 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.

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 cavity is commonly affected by number of lichenoid lesions, whose clinical and histopathologic features overlap due to the presence of inflammatory cells in connective tissue. Segregation of these lichenoid lesions is mandatory as each may embody a distinct disease entity in terms of cause, diagnosis and prognosis. The literature discussed in the article is an attempt to segregate individu...
