Lichenoid tissue reactions can occur in malignant melanoma and may cause partial regression of the lesion. We studied a series of melanomas to determine how frequently lichenoid tissue reaction obscures the diagnosis of malignant melanoma. We retrospectively reviewed 342 cases of invasive malignant melanoma and melanoma in situ from the head, neck, chest, and back. Of the 342 cases, 23 (6.7%) h...

Lichenoid reaction is a mucosal lesion characterized by linear whitish striae appearing on the mucosa and is triggered by external factors like restorative materials, betel nut, tobacco, graft versus host reaction and drugs. A detailed history will help in delineating the two lesions. The review provides an insight into the clinical, histological features and the malignant potential of Lichenoi...

This is a case report of an oral lichenoid drug reaction of the buccal sulci in a female diabetic patient who was on an anti-hypertensive drug, alpha-methyldopa (Aldomet) and an oral hypoglycaemic drug, chlorpropamide (Diabinese). The clinical features, histological findings and management are presented.

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...

Lichenoid reaction represents a family of oral lesions identical, both clinically and histologically to oral lichen planus. The triggering factor for this lesion varies from medicines to dental materials, usually demonstrating a cause-effect relationship unlike lichen planus. We present a typical case of lichenoid reaction on the buccal mucosa that appeared in response to betel quid which progr...

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...
