Oral lichenoid reactions may present as chronic symptomatic mucosal reactions. Lichen planus-like reactions include those associated with drug reactions, graft-versus-host disease after bone marrow transplantation, and idiopathic lichen planus. The mainstay of management is topical steroids; in resistant cases, topical and systemic corticosteroids may be used. We evaluated the use of cyclospori...

Oral lichenoid reactions are considered variants of oral lichen planus and may be regarded as a disease by itself or as an exacerbation of an existing oral lichen planus by the presence of medication or dental materials. They represent a type IV hypersensitivity reaction and most commonly affect the oral mucosa in direct contact with an amalgam restoration. Oral lichenoid reactions can cause si...

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...

Tattoos are common and used extensively as either body art or cosmetic make-up; more rarely, they can be traumatic in nature. We have systemically analysed the literature for the patterns of red pigment tattoo reactions and their treatment options. Our search identified 18 articles; there was 1 non-randomised controlled trial, and the rest were small case studies. In total 139 patients were inc...

BACKGROUND Dental materials, oral hygiene products and food additives may cause contact allergic reactions in the mouth with varied clinical presentation. Oral lichenoid lesions (lichen planus-like lesions) can be induced by hypersensitivity to dental restorative metals, acrylates, flavorings and other substances. AIM The aim of this study was to demonstrate contact allergy to dental material...

BACKGROUND Increased enthusiasm toward newer fashion trends among rural India along with the lack of government regulation has led to increased tattoo reactions. OBJECTIVE The objective of this study is to describe various clinical manifestations of hypersensitive reactions to tattoo ink reported at a tertiary care hospital in Mandya district. MATERIALS AND METHODS An observational study wa...

Lichenoid changes in the oral mucosa can be encountered in a wide range of lesions with varied etiologies including immune-mediated disorders, reactions to systemic medications and to dental materials. Dysplasia of the oral cavity can exhibit a lichenoid histology, which may mask the potentially cancerous component. Another unusual clinical disease, proliferative verrucous leukoplakia, can ofte...

Gabapentin usually has a good safety profile with adequate tolerance. The incidence of adverse reactions in skin, hair and mucosa due to gabapentin is low. Here, we present a case of lichenoid photosensitive eruption due to application of gabapentin in exposed areas. A lichenoid eruption with skin lesions that are widespread distributed requires a drug history as well as stopping the consumptio...

Background and Aim: Oral lichen planus (OLP) is a chronic, inflammatory, T-cell-mediated autoimmune oral mucosal disease. Oral lichenoid lesions develop as a type IV hypersensitivity reaction. Both of these entities are potential precancerous conditions; this adds to their clinical significance. The purpose of this literature review was to detect the similarities and the differences of these le...

We report a case of a 66-year-old male who developed an itchy eruption while taking an antihypertonic drug containing eprosartan and hydrochlorothiacide after sun exposure. The lesions resembled a lichenoid appearance that was confirmed by the histological study. There are few reports in the literature of lichenoid reactions to these compounds, so we review the characteristics of themselves as ...
