ABSTRACT
This study aimed to report the collective clinical characteristics of oral side effects associated with imatinib therapy according to age, sex, and clinical condition. A bibliographic review was performed using the PubMed, Web of Science, Scopus, Cochrane Library, and Embase databases. Forty-five cases of oral side effects due to imatinib therapy were identified in the literature. With the addition of five new cases seen at the authors' institution, a total of 50 cases were analysed. Of the five new cases, four with gastrointestinal stromal tumours developed oral lichenoid lesions (OLLs), and one with chronic myeloid leukaemia (CML) developed oral hyperpigmentation (OHP). Of the total 50 patients, 26 were male and 24 were female, and age ranged from 29 to 86 years. Most patients were ≥50 years old (80%); only three patients were jaw was the least common, with just five cases (10%). Among the patients with OHP, the predominant clinical condition was CML (22 cases, 91.7%). In conclusion, the possibility of oral side effects needs to be considered during the examination of patients receiving imatinib therapy.

Evaluating the association of ABO blood group with different delayed hypersensitivity reactions, such as oral lichenoid reaction (OLR), can provide a new perspective for clinical practice. Therefore, this study designed to investigate ABO blood group antigens in OLR patients. In this case-control study, the ABO blood group of 112 OLR patients and 117 individuals without oral lesions were included. Gender, age, characteristics of the lesions, medications and restorative materials recorded. Chi-square test used to compare the frequency of ABO blood groups in OLR patients with controls. The O blood group was significantly higher in OLR patients and all its subtypes. Also, there were significant relation between O blood group, and severity of lesions. The frequency of dysplasia was non-statistically significant higher in OLR patients with O blood group than other blood group. Based on the results of the present study, O blood group was significantly more in patients with lichenoid reaction than control group, and AB blood group was the lowest. Also, O blood group showed a positive association with the more severe form of OLR lesions and frequency of dysplasia.

Buccal lichenoid lesions (BLLs) are characterised by a unique, linear whitish striation in the buccal region and can be accompanied by ulcers, plaques, erythemas, atrophies and blisters. They are distinguished from oral lichen planus (OLP) by the association of the administration of a drug or contact with a metal. Herein, we present the case of a 42-year-old woman with underlying hypertension with amlodipine-induced BLLs. She complained of a 1-month history of right buccal whitish streaks and oral ulcers 2 months after taking amlodipine. She visited a private otorhinolaryngology clinic, and a biopsy for the right buccal ulcer was conducted. The biopsy result showed features suggestive of OLP. The patient was then diagnosed with OLP. Her symptoms were persistent despite treatment, so a dental referral was made. Amlodipine was suspected as the cause of her condition and was therefore stopped. Her condition gradually resolved after amlodipine withdrawal. Hence, primary care physicians should be aware of BLLs as one of the adverse drug reactions of amlodipine so that prompt management can be taken to avoid further debilitating impacts on patients.
ABSTRACT
@#Oral lichenoid drug reactions (OLDRs) are inflammatory reactions of the oral mucosa caused by the use of specific drugs in sensitive individuals and are classified as oral lichenoid lesions (OLLs). Its clinical and pathological manifestations do not have significant specificity compared to other types of OLL. Various types of drugs have been reported to induce OLDR, including antihypertensive drugs, nonsteroidal anti-inflammatory drugs, hypoglycemic drugs, antipsychotics, and immunosuppressants, among other drugs. Apart from local or systemic administrate glucocorticoids, the most effective treatment measure is to stop using suspicious drugs. Most patients can achieve significant relief from mucosal ulcers and erosion, but white lines may still remain. OLDR has been widely reported in the literature. However, due to a lack of systematic understanding, we do not have a recognized standard for the diagnosis and treatment of this disease. There are still doubts about the causal relationship between related drugs and oral lichen-like lesions. In response to the abovementioned problems, we searched the literature on drug-related oral lichen planus and lichen-like lesions at home and abroad over the past 20 years, most of which were case reports and only a few of which were case-control studies. This article describes the current research status of lichenoid lesions from four perspectives: concepts, suspicious drugs, clinical and pathological manifestations, and treatment prognosis. We hope to provide a theoretical reference for the prevention, diagnosis, and clinical treatment of related lichenoid lesions. A literature review demonstrated that there are still many unclear issues related to the etiology, pathogenesis, clinical diagnosis and treatment, treatment prognosis, and other aspects of this disease, and further clinical and basic research is needed for in-depth exploration.
ABSTRACT
Abstract The aim of this study was to analyze the expression of mast cell markers toluidine blue, c-kit, and tryptase and presence of mononuclear inflammatory cells in oral lichen planus (OLP) and oral lichenoid lesions related to dental amalgam. Nineteen specimens of OLP, OLLC, and healthy oral mucosa were selected. Mononuclear inflammatory cells were analyzed. Histochemical and immunohistochemical analyses were performed using toluidine blue, anti-c-kit and anti-tryptase reagents, and the results were quantified in areas A and B of connective tissue. Mast cells of all OLP and OLLC samples were positive for toluidine blue, c-kit, and tryptase. The density of toluidine blue+, c-kit+ and tryptase+ mast cells was higher in tissue with OLP and OLLC compared with healthy controls (p < 0.05). No difference was noted in mast cells density between OLP and OLLC (p > 0.05). The density of tryptase+ mast cells was higher in the subepithelial region (area A) than the region below it (Area B) in OLLC (p = 0.047). The mononuclear inflammatory cell density was higher in OLLC compared to OLP, but without statistical significance (p > 0.05). A positive statistical correlation was found between mononuclear immune cells and density of c-kit+ and tryptase+ mast cells in OLP (r = 0.943 and r = 0.886, respectively). Our data demonstrate that the etiopathogenesis process of OLP and OLLC modulates the expansion and degranulation of mast cells; mast cells density, however, was similar between OLP and OLLC. The distribution of mast cells appears to vary along the lamina propria.
ABSTRACT
BACKGROUND: The diagnosis of oral lichenoid lesions (OLL) remains a challenge for clinicians and pathologists. Although, in many cases, OLL cannot be clinically and histopathologically distinguishable from oral lichen planus (OLP), one important difference between these lesions is that OLL has an identifiable etiological factor, e.g. medication, restorative material, and food allergy. The list of drugs that can cause OLL is extensive and includes anti-inflammatory drugs, anticonvulsants, antihypertensives, antivirals, antibiotics, chemotherapeutics, among others. This work aimed to perform a literature review of OLL related to chemotherapy drugs and to report two cases of possible OLL in patients with B-cell and T-cell non-Hodgkin lymphomas in use of chemotherapy and adjuvant medications. We also discuss the challenge to clinically and histopathologically differentiate OLL and OLP. CASE PRESENTATION: In both cases, oral lesions presented reticular, atrophic, erosive/ulcerated, and plaque patterns. The diagnosis of OLL was initially established in both cases by the association of histopathology and history of onset of lesions after the use of medications. Although the patients have presented a significant improvement in the oral clinical picture for more than 2 years of follow-up, they still have some lesions. CONCLUSION: A well-detailed anamnesis associated with the drug history, temporal relationship of the appearance of the lesions, and follow-up of patients are fundamental for the diagnosis of OLL related to drugs. Nevertheless, its differentiation from OLP is still a challenge.

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, and lethal lung disease characterized by progressive dyspnea and irreversible loss of lung function. Pirfenidone is a novel anti-fibrotic and anti-inflammatory drug, which reduces deterioration in the lung function and prolongs progression-free survival in patients with IPF. However, it has adverse effects including gastrointestinal symptoms, hepatic dysfunction or skin photosensitivity, and rash. Lichenoid drug eruption (LDE) refers to lichen planus-like drug eruption usually presenting symmetric eczematous plaques with a purple hue. To date, numerous cases of LDE due to various drugs and pirfenidone-associated photosensitivity have been reported. However, a case of pirfenidone-induced LDE has been very rarely reported to our knowledge. Herein, is a case of pirfenidone-induced LDE so that clinicians can be aware of the possibility of LDE when using pirfenidone.
ABSTRACT
Background: Lichenoid reaction (LR) is a relatively common mucocutaneous disease with an unknown etiology. Since the cause of the LRs is unknown, many drugs have been studied to palliate the symptoms. Previous studies reported that corticosteroids are often effective in the management of several oral inflammatory diseases. The aim of the present study was to compare the effect of Melissa gel and triamcinolone 0.1% paste on clinical indices of oral LRs. Materials and Methods: In this randomized clinical trial, sixty patients with erosive oral LRs were randomly divided into two groups, and each group was treated with Melissa gel or triamcinolone acetonide 0.1% paste, three times a day, for 4 weeks. The recovery rate and severity of pain and burning sensation were assessed after 2 and 4 weeks. Finally, the obtained data were analyzed using SPSS software (version 20, IBM Corp., Armonk, NY, USA) and repeated measures ANCOVA, Mann-Whitney test, Chi-square test, paired t-test, and survival analysis.(α = 0.05). Results: The Visual Analog Scale scores for recovery rate, pain, and burning mouth sensation and objective scoring for oral lichen planus were significantly improved at 2 and 4 weeks in both the groups. However, the pain intensity decreased significantly in the Melissa group, as compared to the triamcinolone 1% group. Conclusion: In general, we showed that Melissa gel has a better effect than triamcinolone on pain intensity. Although Melissa gel is effective in reducing lesion size, triamcinolone significantly showed better results.
ABSTRACT
Immune checkpoint inhibitors and their associated immune-related cutaneous adverse events are continuing to become a mainstay of cancer treatment regimens. While most rashes are mild and easily manageable, severe or persistent rashes like lichenoid dermatoses can significantly impact the quality of life and may require ICI cessation. Lichenoid dermatoses currently have no management guidelines beyond the use of topical or oral steroids. Our study is a single-institution retrospective chart review to characterize ICI-induced lichenoid eruptions, their treatments, and associated tumor response. We utilized natural language processing and our institutional medical record to identify patients with lichenoid eruptions on ICI therapy. One-hundred nineteen patients were identified, of which 108 rashes were characterized as lichenoid dermatitis and fifteen as lichenoid mucositis. Most patients presented with a diffuse distribution (86%, 101/117), with pruritus in lichenoid dermatoses (82%, 89/108) and pain in lichenoid mucositis (80%, 12/15). Successful treatments for lichenoid dermatitis included topical steroids (81%, 88/108), oral antihistamines (21%, 23/108), and oral steroids (15%, 16/108). Of lichenoid dermatitis patients, 21% (23/108) did not respond to treatment (7) or required oral steroids (16). Approximately 28% of patients who had lichenoid dermatitis had delay, reduction, or discontinuation of their ICI because of their irCAE. This descriptive study highlights the impact of lichenoid dermatitis on patients' ability to remain on ICI therapy and the need for more effective non-steroidal management strategies.
ABSTRACT
BACKGROUND: Although it is relatively common after hematopoietic cell transplant (HCT), graft-vs-host disease (GVHD) is a rare complication following solid organ transplantation (SOT). METHODS: This study evaluated skin biopsy specimens from five cases of SOT GVHD, 15 cases of HCT GVHD, and 15 cases of cutaneous drug eruption. Immunohistochemical staining for CD3, CD4, CD8, T-bet, and GATA-3 was performed to examine the density and immune phenotype of skin-infiltrating lymphocytes. RESULTS: Similar to HCT GVHD, the predominant histopathologic findings in skin biopsy specimens of SOT GVHD were widespread vacuolar interface dermatitis with scattered necrotic keratinocytes. However, the density of dermal inflammation was considerably higher in SOT GVHD. Features that were more predictive of a cutaneous drug eruption over GVHD included spongiosis, confluent parakeratosis, and many eosinophils. Involvement of the hair follicle epithelium was seen in all three disorders. Both forms of cutaneous GVHD showed a predominance of Th1 (CD3+/T-bet+) lymphocytes within the inflammatory infiltrates. This shift was more pronounced in SOT GVHD, particularly among intraepidermal T-cells. CONCLUSIONS: SOT GVHD shares many histopathologic features with HCT GVHD. However, SOT GVHD has a greater tendency to develop brisk lichenoid inflammation.

Abstract Tattooing one's body is currently a common practice worldwide; however, it is not risk-free. This is a case of a patient who tattooed himself motivated by his passion for motorcycles and then developed an exuberant lichenoid reaction to the red pigment used in the tattoo, with the appearance of verrucous lesions. Despite the lack of response to treatment, he states that he would tattoo his own skin again.

OBJECTIVES: To evaluate the salivary detection of XRCC1 rs25487 single-nucleotide polymorphism (SNP), its relationship with clinicopathological characteristics, and the interactions with demographic/behavioral variables in the etiopathogenesis of oral potentially malignant disorders (OPMD) and oral squamous cell carcinoma (OSCC) in a Colombian population. METHODS: Demographic/behavioral data and saliva samples were obtained from patients with oral leukoplakia (OL, n = 17) and oral lichenoid lesions with epithelial dysplasia (OLL-ED, n = 10), or OSCC (n = 45), along with healthy controls (n = 40). Tissue biopsies were obtained for histological assessment and genetic analysis was performed using polymerase chain reaction-restriction fragment length polymorphism. Descriptive analyses were used to compare the distribution of genotypes/alleles between study groups alongside an analysis of the interaction between genetic findings and demographic/behavioral variables. RESULTS: No association was observed between the genotype and allele frequencies in OPMD or OSCC. The AG genotype was significantly more frequent in OL with high-grade dysplasia, acanthotic epithelial lining, moderate-to-severe mitotic count, and negative-to-mild apoptotic count; and in OSCC cases with stage III/IV, poorly differentiated, perineural/lymphovascular invasion, severe cellular atypia, moderate-to-severe mitotic count, and negative-to-mild apoptotic counts. Significant interaction effects were detected in the AG genotype with regard to ageing, smoking habits, and alcohol consumption in both OL and OSCC. CONCLUSION: Although rs25487 SNP appeared to not modulate the risk of OPMD/OSCC independently, its significant association with clinicopathological characteristics in OL and OSCC, and the synergistic interaction between ageing and smoking/alcohol consumption, might play a role in these two diseases.

BACKGROUND: Increased levels of lactate dehydrogenase (LDH) as a tumor marker have been reported in malignant and some premalignant oral lesions such as oral lichen planus (OLP) and oral lichenoid reactions (OLRs). This study aimed to assess the level of total LDH in the saliva and serum of patients with oral squamous cell carcinoma (OSCC), OLP and OLRs. METHODS: In this case-control study, the participants were divided into four groups (n = 25) of healthy controls, OLP, OLRs, and OSCC. The serum and stimulated/unstimulated salivary levels of LDH were spectrophotometrically measured using standard LDH kits (Pars Azmoun). One-way ANOVA, Chi-square test, Pearson's correlation test, and receiver operating characteristic (ROC) analysis were applied to analyze the data. RESULTS: The serum and salivary levels of LDH in OSCC patients were significantly higher than that the corresponding values in other groups (P = 0.0001). The serum level of LDH in OLR group was significantly higher than that in the control and OLP groups (P = 0.0001), but the difference in salivary level of LDH was not significant. The ROC analysis showed that both the serum and salivary levels of LDH had significant diagnostic ability for detection of OSCC and OLRs. Significant associations were noted between the serum and salivary levels of LDH. CONCLUSIONS: Patients with OSCC and OLRs had higher serum levels of LDH than OLP and control groups. Further prospective longitudinal studies are required to assess the tissue level of LDH and monitor the transformation of OLRs because they have low rate of malignant transformation compared with other oral premalignant lesions.

Extranodal natural killer/T-cell lymphoma (ENKTL) is a rare but aggressive cancer characterised by angiocentric and angiodestructive infiltration by NK-cells, or cytotoxic T-cell types. Histopathologically, ENKTL shows a multinodular or diffuse infiltration localised to vascular structures, resulting in angiodestruction and necrosis. We present a patient with an initially suspected diagnosis of benign interface dermatitis with a differential diagnosis of mycosis fungoides that was later found to be an aggressive extranodal natural killer/T-cell lymphoma of a nasal type and with a dismal prognosis.

ABSTRACT
Laser-Assisted in Situ Keratomileusis (LASIK) is a common surgery for the correction of refractive errors. The majority of patients who undergo this procedure often have excellent results. However, uncontrolled autoimmune disorders and dry eye have both been listed as contraindications to this surgery. Lichen planus (LP) is an autoimmune, inflammatory disorder that characteristically affects mucocutaneous membranes. The etiology is unknown, but it most commonly affects middle-aged adults and presents with bilateral, purple papules. Clinical presentation is used to diagnose the condition, and a punch biopsy is confirmatory. LP may present with multiple different symptoms depending on the type, with ocular manifestations being rare. Multiple viruses and autoimmune conditions have been associated with the disorder, and physicians should take care when gathering a full history of the patient. Exacerbation of symptoms may happen if mood disorders such as depression and anxiety are not well controlled. There are several additional factors physicians must carefully consider before recommending LASIK to patients with LP. These include lichenoid reactions, current medications, and past or present ocular lesions. LASIK may be carefully considered in patients with well-controlled LP in the absence of ocular manifestations. Patients with ocular LP are not candidates for LASIK.
ABSTRACT
Lichen planus (LP) is a chronic mucocutaneous inflammatory condition that typically affects middle-aged adults. Esophageal involvement in LP is rare and underrecognized, often leading to delayed diagnosis and treatment of LP. Herein, we describe three cases of esophageal LP (ELP) in clinically symptomatic patients with endoscopic lesions in the upper to mid-esophagus. This case series suggests that ELP is be more common than was previously thought and emphasizes that clinicians should have a high index of suspicion for this diagnosis, particularly when evaluating proximal esophageal lesions in patients presenting with dysphagia. The series also highlights the successful treatment of our patients with budesonide-honey slurry.
