In their recent publication, Garcia-Pola et al. (1) (2016) suggested the development of proliferative verrucous leukoplakia (PVL) in oral lichen planus (OLP). It was described as a preliminary study, where this association supposedly occurred. They presented a retrospective analysis with a long-term follow-up, showing an interesting relationship between these lesions. It is important to emphasi...

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...

background: oral lichen planus (olp) is a chronic mucocutaneous lesion with unknown etiology. oral lichenoid lesions (oll) comprise a family of lesions with different etiologies. both lesions have similar clinical and histopathologic characteristics although their management is different. differential diagnosis between olp and oll has always been a major challenge. materials and methods: in thi...

This paper reports an interesting development in a 64 year old female originally referred for evaluation of oral lichenoid lesions. The patient had a previous diagnosis of discoid lupus erythematosus of the skin. The presenting oral clinical appearance varied between lichenoid areas and ectopic erythema migrans. At initial presentation the patient had an exophytic lesion on the vermilion of the...

In the last few years there has been a special interest in the definition and classification of so called “premalignant oral diseases” (1). Frequent and controversial processes such as oral lichen planus and other similar oral lesions are included in this group (2, 3). Oral lichen planus is clinically characterized by white papular lineal lesions which show a reticular pattern, associated or no...

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...

There is presently no line of distinction between oral lichen planus and other oral lichenoid lesions. The aim of this study is to determine using histomorphometry, the differences between these lesions. Paraffin sections from 7 normal buccal epithelium, 19 oral lichen planus (LP), 14 oral lichenoid lesions (LL) and 7 discoid lupus erythematosus-like lesions (DLE-ll) were selected. The nuclear ...

Oral lichenoid lesions related to contact are defined as oral-cavity eruptions with an identifiable etiology, and are clinically and histologically similar to oral lichen planus. Within this group are found oral lichenoid lesions related to contact with dental materials (OLLC), the most common being those related to silver amalgam. Currently, it remains difficult to diagnose these lesions due t...

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...
