BACKGROUND "Lichenoid esophagitis" is a descriptive term for a lichenoid pattern of inflammation in the esophagus for which a precise histologic diagnosis cannot be established. The differential diagnosis includes lichen planus, a drug-related reaction, and viral infection. Lichenoid esophagitis causing death has not been reported previously. We describe a case, diagnosed by autopsy, of licheno...

A lichenoid drug eruption is a rare side effect which can occur following the administration of several different medications. Here we describe a unique case of fenofibrate as the causative agent of a lichenoid drug eruption. This case highlights a rare and clinically significant dermatologic side effect of fenofibrate. In addition, we report a potential familial association which underscores t...

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...

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 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 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...

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 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...
