Abstract:
Oral mucosa is often a lone warrior subjected to face many diverse noxious opponents in the form of either hot or cold, acidic or alkaline substances, spiced or not so spicy foods. They may be also in constant contact with tobacco, alcohol, or other substances taken through the mouth or placed in the mouth like amalgam restorations. This paper reports a case of oral lichenoid reaction to amalgam and focuses on the local toxic effects of amalgam as dental restorations with particular reference to oral lichenoid reactions (lesions).

Abstract:
Oral lichenoid reactions (OLR) can be caused by systemic drug exposure. To the best of our knowledge, this is the second report describing a case of OLR induced by rituximab administration in a patient with a diagnosis of non-Hodgkin B-cell lymphoma. After 5 doses of rituximab, a typical pattern of OLP was identified with bilateral and symmetrical lesions on the buccal mucosa and on the right lingual margin. This temporal relationship suggested a probable association between oral lesions and drug therapy. The clinical diagnosis of a rituximab-induced OLR was confirmed by an incisional biopsy r

Abstract:
Introduction. Oral lichen planus (OLP) is a chronic T cell mediated disease of oral mucosa, skin, and its appendages with a prevalence of 0.5 to 2.6% worldwide. Oral lichenoid reactions (OLR) are a group of lesions with diverse aetiologies but have clinical and histological features similar to OLP, thereby posing a great challenge in differentiating both lesions. Mast cells are multifunctional immune cells that play a major role in the pathogenesis of lichen planus by release of certain chemical mediators. Increased mast cell densities with significant percentage of degranulation have been obs

Abstract:
Oral Lichenoid Reaction (OLR) is a chronic inflammatory lesion of the oral mucosa that occurs as an allergic response to certain dental materials, medications and systemic diseases. The frequency of OLR in the general population has been documented to be very less. The clinical and histological features of OLR closely resemble those of Oral Lichen Planus (OLP), making it challenging to distinguish between the two clinically. OLRs might have a higher malignant potential than OLP. The diagnosis and treatment of OLR is very crucial as misdiagnosis may result in detrimental effects on the biophysi

Background: Lichen planus is a common chronic inflammatory disease of the skin and mucous membranes. Oral Lichenoid Reactions (OLRs) comprise a group of lesions with different causative factors such as systemic medication, dental restorative materials, foods, or flavoring agents. Pathologists often group these conditions under the umbrella term of ‘lichenoid processes’.

Material and Methods: The tissue slices used in this investigation were obtained from the archives of the Department of Oral Pathology and were formalin-fixed and embedded in paraffin. The sections were obtained from 40 cases of OLP that were identified by histological examination, as well as 40 cases of OLR. Twenty buccal mucosa samples were obtained from individuals who showed no mouth lesions and did not participate in any oral practices. The study samples were subjected to ha

Abstract:
Lichenoid drug reactions (LDRs) are a type of cutaneous adverse drug reaction that clinically resembles lichen planus and demonstrates lichenoid tissue reaction on histopathology. These have been implicated by various topical, oral, and injectable medications. Noonan’s syndrome (NS) is an autosomal dominant disorder with skeletal deformity, particularly short stature as a common feature for which growth hormone (GH) therapy is effective. Here, we present a 16-year-old male with NS who developed lichenoid dermatitis on initiation of injectable GH therapy and showed remission with oral apremilas
