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 55 year old male patient came for routine dental examination. History revealed that he was a heavy tobacco chewer for the past 20 years. During examination, several radiating white lines were found on top of a slightly grey background, in relation to the right buccal mucosa. The location of the lesion clearly coincided with the site of placement of quid. A differential diagnosis of lichen pla...

Oral lichenoid reactions are disease conditions with definite identifiable aetiology. It can occur either due to intake of drug i.e. lichenoid drug eruptions or due to contact with some potential irritants which majority of times are dental materials. Some other allergens including certain food items are also reported. Some systemic conditions such as chronic liver disease, hepatitis C virus in...

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.

MCI: methylchloroisothiazolinone MI: methylisothiazolinone INTRODUCTION Methylisothiazolinone and methylchloroisothiazolinone (MI/MCI) are broad-spectrum preservatives widely used in cosmetics and household and industrial products. It is well known that MI/MCI can cause allergic contact dermatitis with a spongiotic reaction pattern. Because of this reaction, restrictions have been placed on the...

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...

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...
