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. Patch testing and recognition of the proximity of an offending substance to the eruption can aid with diagnosis 23 yrs old Male asked about Lichenoid reaction, 2 doctors answered this and 17 people found it useful.

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
. 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

(A comprehensive review of the role of chemokines in the pathophysiology of lichenoid tissue reactions.) Thongprasom, K, Dhanuthai, K. Steroids in the treatment of lichen planus: a review The most common signs and symptoms of drug allergy are hives, rash or fever. A drug allergy may cause serious reactions, including a life-threatening condition that affects multiple body systems (anaphylaxis). A drug allergy is not the same as a drug side effect, a known possible reaction listed on a drug label
Adverse reactions to tattooing can occur with different morphologies and histopathologic reaction patterns . Delayed cutaneous reactions can also occur, usually due to red pig-ment, and include granulomatous, allergic, lichenoid, and pseudolymphomatous reactions  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 ()
If an allergic reaction could be triggering an outbreak, you may be referred to a dermatologist or allergist. Self-Management. Good oral care is essential to managing oral lichen planus. Patients should brush gently twice a day with a soft-bristled toothbrush like Colgate 360° Enamel Health, which has 48 percent softer bristles. Sufferers. Lichenoid Mucositis. Lichenoid mucositis (LM) is a condition that can be described as being under the umbrella of OLLs and is also considered a hypersensitivity or allergic reaction to either dental materials (composite, ceramic, or materials other than amalgam) or as a response to a drug the patient is taking Allergic reaction to orthodontic wire: Reporte a case.

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 .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., 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. In reality, every person has a different pain threshold and not every area is deemed to be a painful site for tattooing. How many of us have stopped and thought about the medical aspects surrounding [

Lichenoid reactions due to gold sensitization have been reported, albeit less frequently. [ 58-64 ] The use of amalgam fillings has been largely abandoned in recent years Non-lichenoid cutaneous reactions due to IM have been well-documented in the literature and are the commonest non-hematologic adverse reactions associated with its use.  A case of a generalized lichenoid drug eruption (LDE) associated with imatinib mesylate therapy has been described here for its rarity and unusual clinical presentation Spongiotic, Psoriasiform, and Lichenoid Dermatoses Laura E. 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.
Oral lichenoid reactions (OLR) which are considered variants of OLP, may be regarded as a disease by itself or as an exacerbation of an existing OLP, by the presence of medication (lichenoid drug reactions) or dental materials (contact hypersensitivity). OLP usually presents as white striations (Wickham's striae), white papules, white plaque. Lichenoid Reactions Lichen planus is an inflammatory idiopathic condition of the skin characterized by pruritic reddish-purple, flat-topped bumps. 38 Certain medications can produce a lichenoid-type eruption Oral lichen planus and lichenoid reactions: etiopathogenesis, diagnosis, management and malignant transformation. Ismail SB, Kumar SK, Zain RB.

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. Similarly to the skin, the oral mucosa is affected by a variety of oral lichenoid lesions. Oral LTRs (OLTRs) include: oral lichen planus; oral lichenoid contact lesion; oral.

Whenever possible, chemically unrelated compounds should be substituted for suspect drugs. If no substitute drug is available and if the reaction is a mild one, it might be necessary to continue the treatment under careful watch despite the reaction Allergic reaction; Lichenoid eruptions; Tattooing. Case report. Currently, the practice of tattooing is popular worldwide. This has led to an increase in reactions to tattoo pigments. These reactions are difficult to treat and can sometimes take on curious aspects
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. 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.

Lichenoid allergic reaction. This is rare, but is typically related to red tattoo ink, and characterized by small bumps that appear around the red ink areas. Pseudolymphomatous allergic reaction Lichenoid reactions are those with a known trigger, so this trigger could be discussed in the causes section. A lot of the data about all the different sites in the classification section refer to how the rash presents in each section - this can be discussed more in the symptoms section with a simpler presentation as having a mucosal/cutaneous.
Lichenoid reactions. รอยโรคไลเคนอยด์ในช่องปาก (oral lichenoid lesions) เป็นรอยโรคที่มีลักษณะทางคลินิกคล้ายกับรอยโรคไลเคนพลานัสในช่องปาก (oral lichen planus) ซึ่ง. Results 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 Lichenoid reactions associated with drugs (lichenoid drug reactions) Clinical and histopathologic appearance resembles a delayed hypersensitivity reaction. It has been hypothesized that drugs or their metabolites with the capacity to act as heptans trigger a lichenoid reaction. Drugs which elicit lichenoid drug reactions (LDR) are listed in The aim of the present study was to evaluate mast cell counts and their distribution among OLP and lichenoid lesions. The density and localization of mast cells was examined in 22 patients with a diagnosis of OLP (11 patients) or oral lichenoid reactions (11 patients) by c-kit/CD117 immunohistochemical and toluidine blue histochemical staining
