Oral lichenoid tissue reactions: diagnosis and classificatio

Lichen planus is a skin rash triggered by the immune system. A variety of products and environmental agents can trigger this condition, but the exact cause isn't always known. Sometimes this skin.. Reports associated with lichenoid reactions include various findings such as subepithelial infiltrate that is diffuse and extends deeply. Additionally, reports of increased eosinophils that are also found in allergy-type reactions, parakeratosis and increased plasma cells Abstract: Lichenoid reaction (LR) is clinically and histopathologically similar to lichen planus (LP), which involves the skin and mucous membrane. LR has identifiable etiology and can be triggered by systemic drug exposure or any other agents Lichenoid tissue reaction or interface dermatitis is some of the commonly encountered clinical and histological presentations in dermatology and pathology. The term interface dermatitis refers to the finding in a skin biopsy of an inflammatory infiltrate that abuts or obscures the dermo-epidermal junction

Lichenoid interface dermatitis is the name also used for disorders such as lichenoid dermatitis and indicates that inflammation infiltration with basal-cell-damage seems uncertain in the dermoepidermal junction. This is the area joining epidermal and dermal layers of skin. Lichenoid dermatitis cause Lichenoid reactions A lichenoid reaction happens when small, discolored bumps appear around where the ink was injected. It's most common with red inks. These bumps aren't usually irritating or.. Oral lichenoid contact reactions have been described and are associated with a variety of topical agents including dental materials and flavoring agents . 1, 3, 4, 37 Lichenoid lesions can occur. Oral lichenoid contact reaction (allergic contact mucositis) Oral lichenoid contact reactions may be caused by a variety of substances. The clinical and histologic features of oral lichenoid contact reactions are similar to oral LP.

At this stage of our knowledge of oral lichen planus it is obvious that medications may sometimes cause a so-called lichenoid drug reaction that looks and acts just like conventional oral lichen planus. In fact, on this website we have a long list of medications reported to have caused such reactions The most common type of localized skin reaction is lichenoid, but other reaction patterns have been reported, including eczematous, granulomatous, or pseudolymphomatous. [4-6] Generalized lichenoid reactions to tattoos are much less common, with only four reported cases in the literature to date. [7-10] Tattoos with red ink have consistently been recognized as the most likely to incite a reaction, despite the evolution in tattoo ink formulations over time Lichenoid Reaction. Oral lichenoid reactions may be localized (in response to topical triggers such as restorations) or more widespread, in which case they are usually caused by medication

Components of amalgam may, in rare instances, cause local side effects or allergic reactions referred to as oral lichenoid lesions (OLLs). OLLs to amalgams are recognised as hypersensitivity reactions to low-level mercury exposure Lichenoid contact dermatitis is a rare form of noneczematous contact dermatitis with clinical features resembling lichen planus involving potentially skin and/or mucosal membranes. Lichenoid contact dermatitis has been reported with color developers, such as paraphenylenediamine and its derivatives, nickel, epoxy resins, aminoglycoside. The pathogenic relationship between the oral lichenoid reaction and dental restorative materials has been confirmed many times. Lichen planus-like lesions (2) (oral lichenoid lesion,oral lichenoid reaction) can be caused by hypersensitivity to materials fo Oid-oid disease (Sulzberger-Garbe disease) is an itchy eruption with eczematous and lichenoid features that typically occurs in elderly men. -Erythema dyschromicum perstans (ashy dermatosis) typically presents with gray to violaceous macules, as opposed to the papules and plaques of LP and LDE

Levothyroxine-associated lichenoid drug eruption: A case report and review of levothyroxine-induced adverse reactions Levothyroxine (LT 4) is frequently used as thyroid hormone replacement to treat hypothyroidism. Adverse skin reactions are not common. Lichenoid drug eruption is a one such medication-related reaction. th Lichenoid Allergic Reaction. These are small ink bumps that appear on red ink marks. They are less common eczematous reactions. It is an expression of delayed hypersensitivity to a lymphocytic T-cell infiltrate. It is most common. There are more than 50 known pigments that are currently used in tattooing

Such allergic reactions can be due to contact dermatitis and photoallergic dermatitis. The ink or pigment allergy causes an acute inflammatory reaction and sometimes can produce granulomatous, lichenoid, and pseudolymphomatous types of responses. Specifically, red tattoo dye may contain the following: 1. Ferric hydrate (sienna) 2 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

Adverse reactions to tattooing can occur with different morphologies and histopathologic reaction patterns [11]. Delayed cutaneous reactions can also occur, usually due to red pig-ment, and include granulomatous, allergic, lichenoid, and pseudolymphomatous reactions [2] INTRODUCTION. Lichenoid drug eruptions (LDE) are skin reactions which may be clinically and histopathologically indistinguishable from lichen planus (LP) and are associated with a number of drugs, chemicals, and hepatitis B vaccinations ().In various studies, the mean age of patients with LDE was reported to be 43 to 57 years ().Lichenoid eruptions are rarely seen in the infantile period ()

Oral lichenoid reaction (OLR) or oral lichenoid lesions (OLL) is a term that represent a common end point in response to extrinsic agents (materials, allergens), altered self-antigens, or super antigens. OLL is thus used to describe eruptions of the oral cavity having an identifiable etiology, which are clinically and histologically similar to. Oral lichenoid reaction (OLR) is a type IV cell-mediated immune response in the oral cavity. There is an established relationship between various dental materials and OLR, but few cases reports reported the occurrence of a lichenoid reaction in association with the use of a Hawley retainer. A female patient (twenty years of age) has been complaining of a reddish painful area on the tongue.

Lichenoid drug eruptions resemble lichen planus clinically, but the lesions are often larger, and there is no mucosal involvement. Lichenoid drug reactions frequently occur months to years after the initiation of drug therapy. They may be associated with exposure to various drugs and chemicals such as gold, thiazide diuretics, antimalarials. Drug-Induced Lichen Planus is an uncommon condition that occurs due to certain medications (side effect). It is also known as Lichenoid Drug Eruption (LDE) It mainly manifests as skin lesions on the arms, legs, and trunk. Though, in many individuals the condition is asymptomatic, in some there may be itching from lesions on the skin and pain. Lichen planus (LP) is a chronic disease that involves the skin, scalp, mucous membranes, and nails. The etiology of LP is still unknown; however, some external and internal factors (eg. drugs, stress, hepatitis C virus) have been suggested to trigger the disease. Many studies have investigated an immunologic pathogenesis that is probably related to T-cell autoimmunity with the keratinocyte as. Lichenoid interface dermatitis is seen in numerous conditions, including lichen planus, lichenoid hypersensitivity reactions of drug- or contact-based etiology, lichenoid reactions in the setting of hepatobiliary disease,67 secondary syphilis, and autoimmune CTD. Lichenoid pigmentary purpura of Gougerot and Blum is a form of pigmented purpuric. DISCUSSION. Lichenoid drug eruption is most frequently related to β-blockers, captopril, penicillamine, hydrochlorothiazide, antimalarials, furosemide, quinidine, non-steroidal anti-inflammatory drugs, tetracycline, quinacrine, gold, sulfonylureas, hydroxyurea and methyldopa [3].Although its pathogenetic mechanism is incompletely understood, cell-mediated autoimmune reactions against basal.

The concept of lichenoid tissue reaction/interface dermatitis was introduced in dermatology to define a number of diverse inflammatory skin diseases linked together by the presence of common histopathological features. Similarly to the skin, the oral mucosa is affected by a variety of oral lichenoid. With an increased use of immunotherapy medications such as pembrolizumab for various cancers, it is important that dermatologists are aware of the wide range of adverse cutaneous reactions that can occur, including lichenoid reactions. Hypertrophic lichen planus should be considered in the differential diagnosis of patients with cutaneous lesions in addition to nail findings developing after. Lichenoid hypersensitivity tattoo reactions are less common than eczematous reactions. Evidence exists that the lichenoid reaction is an expression of delayed hypersensitivity to a lymphocytic T-cell infiltrate, which may simulate the graft-versus-host response. Mercury (red pigment) is responsible for most lichenoid tattoo reactions The research of 414 skin reactions logged in the COVID-19 Dermatology Registry from healthcare workers, including board-certified dermatologists, identified a broad range of skin reactions. These include 218 cases of large, delayed reactions near the injection site — dubbed COVID vaccine arm — as well as other types of rashes that include.

Exaggerated sunburn reactions, lichenoid reactions, bullous eruptions; photodistributed slate-grey to violaceous hyperpigmentation Hyperpigmentation seen in long-term, high-dose therapy. Routinely. The lichenoid reaction is to be regarded as a reaction pattern within the oral mucosa directed towards a specific agens in patients predisposed to develop such a reaction. Dental amalgam plays an etiological role in the development of lichenoid reactions and should be removed when in clinical contact with the lichenoid lesion Recently, attention has been directed to the potential and often paradoxical cutaneous adverse effects seen in association with TNF alpha inhibitors including lichen planus-like eruptions, psoriasis, alopecia areata, and lupus-like syndromes.[1],[2] In addition, a variety of lichenoid reactions have been added to the emerging cutaneous adverse. The distinction of oral lichenoid reactions from oral lichen planus may be difficult in a clinical setting. Our aims were to ascertain the utility of patch testing to confirm the association of oral lichenoid reactions with dental restorations and to identify the benefits of replacement of restorations, primarily made of amalgam Histopathologic and immunophenotypic analysis of these lichenoid lesions demonstrated significantly greater histiocytic infiltrates than observed in control lichenoid reactions (p = 0.0134). We also observed increased spongiosis and epidermal necrosis

Signs of an Allergic Reaction to Meth. The signs that there may be an allergic response to using meth are not to be taken lightly, even when taking medically prescribed meth such as Desoxyn. As with many allergic reactions, it can have grave consequences if emergency medical help isn't found right away Among the more common are eczematous, morbilliform, and lichenoid dermatoses, as well as vitiligo and pruritus. Less common adverse events include psoriasiform dermatoses, bullous disorders, and severe cutaneous adverse reactions, including Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic. When one stops and thinks about tattoos, many seem only to relate with the pain factor involved when getting tattooed.

K. Gifford Emily J. Osier Charlene W. Oldfield Judith V. Williams Alejandro A. Gru ATOPIC DERMATITIS Definition and Epidemiology Atopic dermatitis is a chronic, relapsing inflammatory skin condition defined by pruritus.1 The most widely used diagnostic criteria specify that a patient must have pruritus with an eczematous dermatiti The lichenoid pattern on histologic analysis is a remarkably consistent finding and appears to be a distinct feature compared with cutaneous reactions seen with other immunotherapies. Notably, the eruptions are usually relatively mild and can be typically adequately managed with topical corticosteroids Answer: Lichenoid drug eruptions can have a mean latent period of one year from the start of a new medication and the onset of the skin rash. This long interval can make identification of the trigger difficult. In addition to the medications that you mentioned, vaccines and statins have been reported to cause this condition

Oral Lichenoid Contact Reactions Oral lichenoid lesions can be a diagnostic challenge for the pathologist due to the tremendous overlap in the clinical and pathologic presentation of many inflammatory, reactive, and immune -mediated disorders than commonly involve the oral mucosa Released mercury is reported as being taken up by oral soft tissues 10,11 and in some patients this appears to result in local toxic or allergic effects that present as oral lichenoid lesions (oral lichenoid reactions) OLLs. 6,7,10,11,12,13 Clearing of the lesions after removal of amalgam restorations in such patients has been reported. Purpose Drug-induced oral lichenoid reactions (DIOLRs) have been extensively reported in the literature, but the validity of the causality relationship between any drug and the oral lichenoid lesions (OLLs) still remains questionable. We sought to determine whether this causality relationship really exists, whether a resolution of the oral lesions upon withdrawal occurs, and what the most.

Reactions Similar to OLP. Patients may experience reactions that are similar clinically and /or microscopically to lichen planus. These are called lichenoid reactions. The most common cause of lichenoid reactions is drugs. A variety of systemic medications are known to induce these reactions and patients whose lichen planus developed. Oral lichenoid reactions related to mercury sensitivity. Br J Oral Maxillofac Surg. 1987; 25(6):474-80 (ISSN: 0266-4356) James J; Ferguson MM; Forsyth A; Tulloch N; Lamey PJ. Lichen planus is a common disorder of unknown aetiology Lichenoid reactions have subsequently been reported in association with many agents (amalgam, composite resins, and dental restorative materials). A number of drugs have been implicated in lichen planus-like eruptions. The most common agents are nonsteroidal anti-inflammatory drugs and angiotensin converting enzyme inhibitors Erosive OLP and lichenoid drug reactions can be indistinguishable both histologically and clinically. Some of the drugs commonly associated with lichenoid reactions are nonsteroidal anti-inflammatory drugs, diuretics, angiotensin-converting enzyme inhibitors, beta-blockers and antimicrobials (Table 1).1 The concept of lichenoid tissue reaction/interface dermatitis was introduced in dermatology to define a number of diverse inflammatory skin diseases linked together by the presence of common histopathological features.

Lichenoid reaction as an allergic reaction to dental materials has been widely reported. Many studies have documented contact hypersensitivity to dental materials such as amalgam (11-13), composite (14) and dental acrylics (15) presenting as lichenoid reactions. Some studies also showed resolutio Foreign body reactions should be considered in the differential diagnosis of localized inflammatory nodules and plaques, especially when there is a persistent draining wound or sinus. Occasionally, these reactions present as pyogenic granulomas or localized lichenoid papules The systemic adverse effects of tumor necrosis factor alpha (TNF) inhibitors are well known.
