Abstract
BACKGROUND This systematic review aimed to conduct a complete investigation of the demographic aspects, clinicopathological features, degrees of epithelial dysplasia, and malignant transformation rate of actinic cheilitis. METHODS The study was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and registered in the International Prospective Register of Systematic Reviews (CRD42020201254). A search without year and language restrictions was performed using PubMed/MEDLINE, Embase, Virtual Health Library, Scopus, Web of Science, and gray literature. Studies that provided information on patients with actinic cheilitis were included, excluding those with general information on other diseases or other types of cheilitis. Risk of bias was explored using the Joanna Briggs Institute tool. Narrative and quantitative data syntheses were performed using meta-analyses and subgroup analyses. Association tests were also performed. RESULTS Thirteen studies (728 patients) were included. The most prevalent clinical signs were dryness (99%), blurred demarcation between the lip vermilion and skin (82%), scaling (69%), and atrophy (69%). Regarding epithelial dysplasia, a prevalence of mild dysplasia (34.2%), followed by moderate (27.5%), and severe (14.9%). The malignant transformation rate was 14%. Crusts, ulcerations, and erythematous areas were associated with lip carcinoma (p < 0.001), and scaling was associated with actinic cheilitis (p < 0.001). CONCLUSIONS This study revealed several features of actinic cheilitis, providing an overview of the disease. It is suggested that new studies help develop policy guides for the standardization of clinical criteria, enabling more rigorous and homogeneous analysis of actinic cheilitis.

Laminin Immunostaining in Biopsies as a Useful Biomarker of Early Invasion in Actinic Cheilitis and Differential Diagnosis Between Actinic Cheilitis and Lip Cancer: New Insights. Head Neck Pathol 2022:10.1007/s12105-022-01504-y. [PMID: 36303015 DOI: 10.1007/s12105-022-01504-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Accepted: 09/25/2022] [Indexed: 02/09/2023]
Abstract
BACKGROUND Squamous cell carcinoma of the lip (LSCC) and oral cavity can be life-threatening if not diagnosed early. Precancerous lesions like actinic cheilitis (AC), can transform into LSCC. Laminin is a fundamental component for basement membrane (BM) and its integrity may prevent neoplastic invasion. Therefore, laminin immunostaining of BM may be useful in identifying early invasion in actinic cheilitis and thus in the differential diagnosis between AC and invasive LSCC or high-grade epithelial dysplasia (ED). MATERIALS AND METHODS Biopsies from 46 patients with oral lesions were histologically analyzed and immunohistochemically stained for laminin-1. RESULTS AC was diagnosed in 34 patients and LSCC in 12 patients, including 3 patients with AC and concomitant high-grade ED/in situ carcinoma. Laminin-1 immunostaining revealed intense and linear expression of the BM in AC with low-grade ED. Loss of laminin expression was observed in LSCC. Intracellular laminin expression in parabasal cells was noted in AC with high-grade ED/in situ carcinoma. CONCLUSION Laminin immunostaining could be useful in identifying AC cases suspected of early invasion. It could also contribute to the histopathological differential diagnosis between AC with low- and high-grade ED and between AC and invasive LSCC. The findings of this study provide new insights into the mechanism involved in the progression process of AC into LSCC, encouraging preclinical studies that may document the stochastic role of laminin in this process.

Abstract
Actinic cheilitis (AC) is a chronic inflammation of the lip considered an oral, potentially malignant disorder associated with an increased risk of lip squamous cell carcinoma (SCC) development. Controversies surrounding current therapeutic modalities of AC are under debate, and the implications of laser treatment have not been specifically investigated through a systematic review design. The present study aims to evaluate the degree of evidence of laser for the treatment of AC in terms of efficacy and safety. We searched for primary-level studies published before January 2022 through MEDLINE/PubMed, Embase, Web of Science, Scopus and CENTRAL, with no limitation in publication language or date. We evaluated the methodological quality and risk of bias of the studies included using the updated Cochrane Collaboration's tool for assessing risk of bias (RoB-2). Twenty studies (512 patients) met our eligibility criteria. Laser therapy showed a complete clearance of AC in 92.5% patients, with a maximum recurrence rate of 21.43%, and a very low frequency of malignant transformation to SCC (detected in only 3/20 studies analyzed). In addition, cosmetic outcomes and patient satisfaction were described as excellent. In conclusion, our findings indicate that laser therapy is a high efficacy approach to AC.

Abstract
Background:
Actinic cheilitis, herpes labialis and lip cancer are relatively common conditions presenting on the lips associated with exposure to periods of sun exposure and thereby ultraviolet radiation.
Objective:
This systematic review aimed to determine the efficacy of the application of sunscreen-containing lip-protecting agents (LPA) in the prevention of actinic cheilitis (AC), recurrent herpes labialis (RHL) and lip cancer (LC).
Methods:
This review was conducted in accordance with the PRISMA guidelines and registered with the PROSPERO database. A literature search was conducted using SCOPUS, Google Scholar, Medline (Ovid), Pubmed, CINAHL, Cochrane Library databases and manual search using search terms actinic cheilitis (AC), recurrent herpes labialis (RHL) and lip cancer (LC) along with lip protecting agents and their variations as keywords. A total of 1,567 papers were yielded. Of them, nine studies were eligible for qualitative data synthesis.
Results:
Nine articles (3 AC, 5 RHL, 1 LC) were deemed eligible and thus selected for qualitative synthesis. Three studies on AC identified approximately 21.7% lower prevalence of lesions when some form of lip protection was used. Eighty percent of studies on RHL identified that the application of LPA is effective in preventing RHL. Subjects who applied LPA more than once daily only had half the risk of having LC compared to those who applied once daily.
Conclusion:
This review of randomised controlled trials (RCTs) and observational studies supports the use of LPA as an effective method in preventing lip-associated lesions. Further, RCTs and observational studies should aim at determining a definitive LPA application regime and optimal SPF strength to prevent lip-associated lesions.

Abstract
AIMS To discuss the terminology to define and classify actinic cheilitis (AC) and to build a consensus on the diagnostic and therapeutic approaches to AC. METHODS Two-round Delphi study using a questionnaire including 34 closed sentences (9 on terminology and taxonomy, 5 on potential for malignant transformation, 12 on diagnostic aspects, 8 on treatment) and 8 open questions. Experts' agreement was rated using a Likert scale (1-7). RESULTS A consensus was reached on 24 out 34 statements (73.5%) and on 5 out of 8 (62.5%) close-ended questions. The response rate was identical in both rounds (attrition of 0%). AC is the term with the highest agreement (median of 7 (strongly agree; IQR: 6-7)) and the lowest dispersion (VC = 21.33). 'Potentially malignant disorder' was the preferred classification group for AC (median of 7) and 85.6% of participants showing some level of agreement (CV < 50). Experts (66.75%) consider AC a clinical term (median: 7; IQR: 4-7) and believe definitive diagnosis can be made clinically (median: 6; IQR: 5-7), particularly by inspection and palpation (median: 5; IQR: 4-6). Histopathological confirmation is mandatory for the management of AC (median: 5; IQR: 2.5-7), even for homogeneous lesions (median: 5; IQR: 3.5-6). Consensus was reached on all treatment statements (VC < 50). CONCLUSIONS AC is a potentially malignant disorder with a significant lack of agreement on diagnostic criteria, procedures, biopsy indications and the importance of techniques to assist in biopsy. A consensus was reached on nomenclature and management of this disorder.

Abstract
INTRODUCTION Oral epithelial dysplasia is considered a potential histologic precursor of subsequent squamous cell cancer. As standard clinical practice, pathologists grade dysplasia to assess risk for progression to malignancy. Except for the most advanced grade, severe dysplasia, dysplasia grading has failed to correlate well with the risk to develop invasive cancer. The questions of what process dysplasia grading best represents and what clinical utility dysplasia grading may have are explored. AREAS COVERED This narrative review is based on PubMed search with emphasis on papers since 2010. Epithelial dysplasia as a precursor lesion of cancer and dysplasia grading as a risk assessment tool for progression to cancer are discussed. The close clinical association of dysplasia with known carcinogens, alcohol, and tobacco products is presented. EXPERT OPINION Oral epithelial dysplasia is often, associated with prolonged exposure to tobacco and alcohol products. With reduction of carcinogen exposure, dysplasia is known to regress in some cases. It is proposed that histologic dysplasia grade together with macroscopic images of dysplastic clinical lesions be used as an educational tool to incentivize patients to reduce their known carcinogen exposure. This strategy has the potential to reduce lesion progression thereby reducing the disease burden of oral cancer.

Abstract
Background: Actinic cheilitis (AC) is a premalignant lesion of the lips that can evolve into squamous cell carcinoma. Among nonsurgical treatments, photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) patch might represent a new noninvasive therapeutic approach for AC. Objective: We sought to investigate the potential role of fractional CO2 laser pretreatment in boosting ALA penetration and distribution into AC treated with PDT. Methods: We report a case of a woman with AC on the lower lip, treated with ablative fractional CO2 laser to boost drug delivery of 5-ALA patch before PDT treatment. Reflectance confocal microscopy was performed to assess diagnosis and treatment response. Results: We detected a good clinical and cosmetic outcome after two applications of combined treatment. Erythema, crust, and edema were reported as side effects. Conclusions: This case report shows that ablative fractional CO2 laser-assisted PDT might be an effective therapeutic alternative for patients with AC who refuse or are contraindicated for surgical procedures.

Abstract
OBJECTIVE To determine whether sun protection is associated with lower occurrence of actinic cheilitis in adults living in a city from southern Brazil. MATERIALS AND METHODS A multi-stage proportional sample of 404 individuals 18 years and older was obtained. Interviews and clinical examinations were conducted in participants' households. Four categories of self-reported use of sun protection were determined. Multivariable Poisson regression was used to assess the associations. RESULTS Prevalence of actinic cheilitis was 47.1%. In the first main-effects multivariable model, AC was significantly associated with sex, age, skin colour and duration of sun exposure, but not with sun protection. However, the association between sun protection and actinic cheilitis was modified by the time of sun exposure. Among those exposed ≥4 hr/day to sun, individuals using physical protection or physical + chemical protection were 33% (prevalence ratio = 0.67, 95% confidence interval [CI] 0.47-0.94, p = .02) and 36% (PR = 0.64, 95% CI 0.47-0.94, p = .02), respectively, less likely to have actinic cheilitis than those who did not use any sun protection, adjusting for sex, age and skin colour. CONCLUSIONS Physical and chemical sun protection were associated with lower occurrence of actinic cheilitis in individuals with greater exposure to sun.

Abstract
Oral potentially malignant disorders (OPMDs) are associated with an increased risk of occurrence of cancers of the lip or oral cavity. This paper presents an updated report on the nomenclature and the classification of OPMDs, based predominantly on their clinical features, following discussions by an expert group at a workshop held by the World Health Organization (WHO) Collaborating Centre for Oral Cancer in the UK. The first workshop held in London in 2005 considered a wide spectrum of disorders under the term "potentially malignant disorders of the oral mucosa" (PMD) (now referred to as oral potentially malignant disorders: OPMD) including leukoplakia, erythroplakia, proliferative verrucous leukoplakia, oral lichen planus, oral submucous fibrosis, palatal lesions in reverse smokers, lupus erythematosus, epidermolysis bullosa, and dyskeratosis congenita. Any new evidence published in the intervening period was considered to make essential changes to the 2007 classification. In the current update, most entities were retained with minor changes to their definition. There is sufficient evidence for an increased risk of oral cancer among patients diagnosed with "oral lichenoid lesions" and among those diagnosed with oral manifestations of 'chronic graft-versus-host disease'. These have now been added to the list of OPMDs. There is, to date, insufficient evidence concerning the malignant potential of chronic hyperplastic candidosis and of oral exophytic verrucous hyperplasia to consider these conditions as OPMDs. Furthermore, due to lack of clear evidence of an OPMD in epidermolysis bullosa this was moved to the category with limited evidence. We recommend the establishment of a global research consortium to further study the natural history of OPMDs based on the classification and nomenclature proposed here. This will require multi-center longitudinal studies with uniform diagnostic criteria to improve the identification and cancer risk stratification of patients with OPMDs, link them to evidence-based interventions, with a goal to facilitate the prevention and management of lip and oral cavity cancer.

Abstract
Actinic cheilitis (AC) is one of the most frequent pathologies to affect the lips. Studies show that the most commonplace oral malignancy, squamous cell carcinoma (SCC), often emerges from AC lesions. Invasive diagnostic techniques performed on the lips carry a high risk of complications, but reflectance confocal microscopy (RCM), a non-invasive skin imaging technique, may change the current diagnostic pathway. This retrospective study was aimed at consolidating the RCM diagnostic criteria for AC and lip SCC. The study was conducted in two tertiary care centers in Bucharest, Romania. We included adults with histopathologically confirmed AC and SCC who also underwent RCM examination. Of the twelve lesions included in the study, four were AC and eight were SCC. An atypical honeycomb pattern and the presence of target cells in the epidermis were RCM features associated with AC. SCC was typified by the presence of complete disruption of the epidermal architecture and dermal inflammatory infiltrates. The mean blood vessel diameter in SCC was 18.55 µm larger than that in AC (p = 0.006) and there was no significant difference (p = 0.64) in blood vessel density, as measured by RCM, between SCC and AC. These data confirm that RCM can be useful for the in vivo distinction between AC and lip SCC.

Abstract
Early identification and adequate treatment of actinic cheilitis (AC), which affects the lower lip vermillion and is considered a precursor of squamous cell carcinoma, is mandatory. Photodynamic therapy (PDT) has been successfully used in AC. PDT with the use of daylight (DLPDT) is equally effective and more convenient than the conventional PDT. Data on short and long-term efficacy of DLPDT in AC are limited. Our primary purpose was to assess efficacy of DLPDT in AC as well as safety and tolerance. Twenty-two individuals with histologically confirmed AC received 2 MAL (5-aminolevulinic acid)-DLPDT sessions 1 week apart. Patients were evaluated clinically 3, 6, and 12 months after treatment. Non-complete responders were biopsied and excluded from the study if histological alterations were indicative of AC. Adverse events were recorded from baseline to the end of the 12-month follow-up period. Twenty patients completed the study. Overall, complete clinical response 12 months after treatment was 80% (16/20), while an association between treatment response and grade of dysplasia was observed (p = 0.016). With respect to response by grade, complete clinical response achieved in grade I AC was 100% (12/12) and 50% (4/8) in grade II AC. Main adverse events included mild erythema, oedema, and scaling, with no pain associated with DLPDT. According to our results, DLPDT seems to be of significant benefit for the treatment of grade I AC. Combination with the other treatment modalities could improve the efficacy in grade II AC. Further studies are needed for the assessment of late recurrences.

Abstract
Precancerous lesions of oral mucous membrane diseases and oral cancer are common diseases in developing countries, especially in South Asia. However, the cancerous mechanism remains unclear, and no efficient treatment and prognosis measure are currently available. Thus, precancerous lesions of the oral mucosa and oral cancer animal models must be identified to further understand their function. In this paper, we systematically review the development of oral mucosal precancerous lesions and oral cancer animal models by referring to related research.

J Eur Acad Dermatol Venereol 2020; 34:2011-2015. [PMID: 31999856 PMCID: PMC7496675 DOI: 10.1111/jdv.16247] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2019] [Accepted: 01/08/2020] [Indexed: 11/29/2022]
Abstract
Background Actinic cheilitis (AC) is a variant of actinic keratosis (AK) affecting the lips and caused by chronic ultraviolet exposure. Objective Alacare is a self‐adhesive, skin‐coloured 5‐aminolaevulinic acid patch that has been developed for use in photodynamic therapy (PDT) of mild‐to‐moderate AK. Based on promising preliminary results in the treatment of AC with Alacare patch PDT, we decided to extend our previous investigation to gain more data on the efficacy, tolerability, safety and cosmetic outcome of Alacare patch PDT for AC. Methods Twenty‐one patients with a clinical diagnosis of mild‐to‐moderate AC were included in the study and subjected to one single session of PDT. After occlusion with the Alacare patch for 4 h, the AC lesions were illuminated for 10 min with red light at a dose of 37 J/cm2. All patients received local anaesthesia prior to illumination. Additionally, all lesions were cooled during PDT with a cold air blower. PDT‐induced pain and skin phototoxicity were monitored during and up to 7 days after PDT. Clinical assessment of efficacy, cosmetic outcome and global patient satisfaction was performed at 3, 6 and 12 months after treatment. Results Nineteen patients completed the study. Three months after PDT, 17 patients (89.5%) had achieved complete remission. Of these, one patient presented with recurrence of AC at the 6‐month follow‐up, whereas all other patients remained in remission until the end of the observation period. The complete clinical cure rate at 1 year after a single Alacare patch PDT thus was 84.2%. Pain during illumination and the phototoxic skin reaction were in general mild to moderate. The cosmetic outcome was excellent. Conclusion The present prospective study on Alacare patch PDT for AC confirms its high clinical efficacy, good tolerability and favourable cosmetic effects. Alacare patch PDT should be considered as a valid treatment option for patients with AC.

Abstract
Data on the occurrence and clinicopathological characteristics of actinic cheilitis (AC) and lip squamous cell carcinoma (LSCC) are well studied; however, they are based on studies limited to a single centre. Herein, we described the frequency of AC and LSCC submitted to microscopic examination from representative geographic regions of Brazil. A retrospective multicentre study was performed on biopsies obtained from 1953 to 2018 at 10 Brazilian oral and maxillofacial pathology centres. A total of 198,709 biopsy specimens were surveyed. Sociodemographic data and clinicopathologic characteristics were analysed. A total of 2017 cases of ACs (1.0%) and 850 cases of LSCCs (0.4%) were recorded. A strong fair-skinned (> 87%) male (> 70%) predilection was observed in both conditions. The mean age was 54.8 ± 18.7 for individuals with AC and 57.8 ± 19.0 for individuals with LSCC. The most commonly affected site was the lower lip (> 90%). This is a large multicentre study of AC and LSCC from Brazil. The frequency and clinicopathological features of AC and LSCC were similar to those described worldwide. This study provides robust and representative epidemiological data of these conditions for the scientific community.

Abstract
Actinic cheilitis (AC) is a potentially malignant lesion caused by chronic sun exposure. This study aimed to evaluate the relationship between the degree of epithelial dysplasia and morphometric findings in AC. Sixty-eight slides of AC cases were selected and classified according to the grade of epithelial dysplasia, following morphologic criteria of World Health Organization. For morphometric analysis, the slides were scanned and images were analyzed using Pannoramic Viewer software. We obtained vertical measurements of the parameters: thicknesses of the keratin layer, lamina propria and zone of solar elastosis in three selected fields. Thirty-seven (54.4%) of the analyzed cases were classified as none/mild dysplasia and 31 (45.6%) as moderate/severe epithelial dysplasia. Cases with a moderate/severe dysplasia exhibited a thicker layer of keratin (median = 0.055 mm) than none/mild dysplasia (median = 0.045 mm) (p = 0.033). No significant differences in the thicknesses of lamina propria and zone of solar elastosis were observed according to the grade of epithelial dysplasia. A positive significant correlation between keratin layer and lamina propria thicknesses was found (p = 0.019). Based on our findings, rigorous clinical follow-up should be recommended for patients whose histopathological examination shows a greater thickness of the keratin layer.

Abstract
BACKGROUND The frequency and distribution of oral potentially malignant disorders (OPMD) may vary among different populations. The aim of the present study was to evaluate the clinical-pathological characteristics of OPMD diagnosed in a Brazilian oral pathology laboratory over a period of 11 years. MATERIAL AND METHODS All cases diagnosed as leukoplakia, speckled leukoplakia, erythroplakia, and actinic cheilitis from 2005 to 2015 were analyzed. Clinical information was obtained from laboratory forms and histological information was obtained from histological slides stained with hematoxylin and eosin. RESULTS the final sample was comprised of 684 cases, of which 292 were males and 392 were females. The mean age was 58 years. The anatomical site most often involved was the lateral border of the tongue (23%), followed by the lower lip (20%), and by the buccal mucosa/vestibule (18%). Leukoplakia accounted for 82% of the sample (564 cases). The mean size of the leukoplakia and speckled leukoplakia lesions was 13 mm (ranging from 1 to 100 mm) and 15 mm (ranging from 5 to 30 mm), respectively (p=0.460). Males reported smoking and drinking alcohol more frequently than females (p=0.001 and p<0.0001, respectively). In half of the cases, dysplasia was not histologically detected, while slight dysplasia was detected in 28% of the cases. The lesions from patients aged from 41 to 80 years presented moderate and severe dysplasia more often than lesions from patients in other age groups. CONCLUSIONS OPMD were more common in females in their sixties. Females were more frequently affected in all anatomical sites, except for the lips. Leukoplakia lesions were the most common OPMD, followed by actinic cheilitis. The lateral border of the tongue was the most affected anatomical site. OPMD located in the floor of the mouth/sublingual mucosa and lesions from older patients presented severe epithelial dysplasia with greater frequency.

Abstract
Oral epithelial dysplasia is a spectrum of architectural and cytological epithelial changes caused by accumulation of genetic changes, and is associated with an increased risk of progression to squamous cell carcinoma. It is a microscopic diagnosis of immense clinical importance. The initial reports of oral potentially malignant disorders with oral epithelial dysplasia transforming to oral cancer helped in understanding the nature of oral malignancies. Since then, clinical studies on oral potentially malignant disorders have combined microscopic findings of oral epithelial dysplasia to assess the malignant transformation potential of different grades of epithelial dysplasia. A significant amount of scientific literature has amassed on oral epithelial dysplasia relating to aspects of its diagnosis and management. However, the evidence base is weak as a result of the significant variability of published research. Poorly described study methods, variability in different oral epithelial dysplasia grading systems, inter- and intra-examiner variability causing issues of reliability, inadequate sample size, and inconsistent durations of follow-up are some of the methodological issues contributing to the failure to provide dependable information. Randomized clinical trials on the malignant transformation potential of oral epithelial dysplasia and its treatment outcomes are limited. This comprehensive literature review on oral epithelial dysplasia summarizes the scientific knowledge published in the scientific literature in English since its first description. The historical development, etiological factors, grading systems, diagnostic criteria, assessment of risk factors and prevention of malignant transformation, management principles of different grades of oral epithelial dysplasia (surgical and nonsurgical), recommendations on follow-up, and prognostic indicators are discussed in detail.

Abstract
OBJECTIVES The objective of the study is to assess, by clinical follow-up, the efficacy of the dermatological cream Fludroxycortide 0.125 mg/g (Drenison®) in the treatment of actinic cheilitis (AC). MATERIAL AND METHODS Twenty-three patients diagnosed with AC participated in the study. Fifteen were submitted to corticotherapy with Fludroxycortide, applied three times a day for up to 6 weeks, associated with lip sunscreen (LS) before sun exposure. In the control group of eight patients, only the use of LS was established. At each weekly return, a photographic record was made of the lesion. After treatment, images were evaluated and scores were assigned to verify clinical evolution. Also, patients treated with Fludroxycortide responded to a questionnaire, to assess drug tolerability and treatment satisfaction. RESULTS In the group treated with Fludroxycortide (n = 15), five patients showed total improvement, seven presented partial improvement, and three showed no clinical change. Concerning the patients treated with LS (n = 8), one presented total remission of the clinical lesion characteristics, four exhibited partial improvement, and three exhibited no clinical lip alteration. No case presented symptom worsening. Of the 15 patients undergoing corticotherapy, 12 were satisfied and reported that the product was not irritating and contributed to lesion improvement. CONCLUSIONS Conventional treatment with LS was effective in the remission of some AC lesions, but treatment responses were improved when associated with Fludroxycortide, especially in the more severe cases. CLINICAL RELEVANCE As it is a non-invasive therapy leading, in most cases, to adequate clinical results, safety, and tolerability, Fludroxycortide can be considered an effective alternative treatment for AC.

Abstract
Background To investigate the prevalence of malignant and potentially malignant lesions of the lip in an oral pathology service and to compare these data with a literature review. Material and Methods A total of 3173 biopsy reports and histopathological records were analyzed. Cases with a histological diagnosis of actinic cheilitis (AC) with or without epithelial dysplasia, in situ carcinoma, or lip squamous cell carcinoma (LSCC) were included. A comprehensive literature review was conducted to investigate the prevalence of AC and/or LSCC. Results 124 cases (3.91%) were included, 75 (60.5%) had some degree of epithelial dysplasia and 31 (25.0%) were LSCC. Clinically, most of the lesions were diagnosed as AC (50.8%); however, eight cases clinically reported as AC were histologically diagnosed as LSCC. Regarding clinical characteristics, most individuals were fair-skinned male, with mean age of 54.3±12.3 years, and with a history of long-term solar exposure. Furthermore, 18 articles were selected from the literature, showing that the lower lip was predominantly affected and that most individuals were males, fair-skinned, and older than 40 years. Conclusions Since most of the cases diagnosed clinically as AC presented some degree of epithelial dysplasia, it is important to emphasize the value of biopsy and the histological evaluation of this lesion. Key words:Actinic cheilitis, Precancerous conditions, In situ carcinoma, Oral diagnosis, Mouth neoplasms.

Abstract
An early diagnosis is of overwhelming importance for the management and prognosis of mucocutaneous cancer. Actinic cheilitis (AC), defined by the clonal expansion of genomically unstable keratinocytes, is the most common potentially malignant lesion affecting the lips. Squamous cell carcinoma (SCC) is the most frequent oral malignancy, and there is strong evidence that the majority of the SCCs of the lip originate from AC. There is considerable difficulty in discerning between dysplasia and invasive carcinomas solely on a clinical basis. Although dermoscopy has become an essential tool for skin tumor evaluation, reflectance confocal microscopy (RCM) is a non-invasive imaging technology that has proved itself extremely useful in the diagnosis and monitoring of several skin diseases, including AC and SCC. The present study aimed to re-emphasize the usefulness of RCM in the early detection of malignant transformation, using AC and SCC of the lips as working examples. Due to the apparent innocuousness of AC for numerous patients, it is not possible to overstress the importance of a correct and early diagnosis, proper treatment and long-term patient follow-up as being essential for preventing the progression to lip SCC, or for its timely diagnosis.

Abstract
Abstract The objective of the present study was to determine the prevalence of actinic cheilitis among extractive mining workers and factors associated with the condition, especially the relationship between clinical appearance and the length of occupational exposure to sunlight. A cross-sectional study was performed in Dona Inês, Paraíba, Brazil between 2014 and 2015. A clinical examination, clinical photography and a questionnaire were applied to 201 extractive mining workers. The T-student’s, ANOVA one-way, Fisher’s exact and Pearson chi-squared tests were performed and the significance level was set at 5%. A high prevalence of actinic cheilitis was observed (38.8%). Length of occupational exposure to sunlight in months (169.63±112.68, p=0.002) was associated with actinic cheilitis. Most workers were Caucasian (p<0.001) and aged 37.41±12.15 years (p=0.004). The time of occupational exposure to sunlight was significant in relation to the following clinical features: atrophy (225.75±97.31; p=0.024); blurred demarcation between the vermilion border of the lip and the skin (186.68±113.15; p=0.032); vertical fissures (210.09±123.07; p=0.046); white and red spotting (199.51±91.80; p=0.004); hard consistency of the lip (225.81±122.34; p=0.012). A high prevalence of actinic cheilitis was found. Age and ethnicity were associated with the presence of AC. Severe clinical presentations of actinic cheilitis were found among participants who had worked for at least 185 months (approximately 15 years) exposed to the sun.

Abstract
Heath care providers should be comfortable with normal as well as pathologic findings in the lips, because the lips are highly visible and may display clinical manifestations of local, as well as systemic inflammatory, allergic, irritant, and neoplastic alterations. Fortunately, the lips are easily accessible. The evaluation should include a careful history and physical examination, including visual inspection, as well as palpation of the lips and an examination of associated cervical, submandibular, and submental nodes. Pathologic and microscopic studies, as well as a review of medications, allergies, and habits, may further highlight possible etiologies. Many lip conditions, including premalignant changes, are relatively easy to treat, when the abnormalities are detected early; however, advanced disease and malignancies are challenging for both the patient and clinician. Treatment should be focused on eliminating potential irritants or allergens and treatment of the primary dermatosis. In this paper we review physiologic variants as well as pathologic conditions of the lips.

Thioredoxin and metallothionein: Homeostasis-related proteins in lip carcinogenesis. Arch Oral Biol 2017; 77:75-81. [PMID: 28183007 DOI: 10.1016/j.archoralbio.2017.01.020] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2016] [Revised: 01/27/2017] [Accepted: 01/28/2017] [Indexed: 02/06/2023]
Abstract
OBJECTIVE Thioredoxin (Trx) and metallothionein (MT) are involved in the development of some carcinomas; however, the role of these proteins in labial carcinogenesis has not yet been tested. The aims of the study were to evaluate and to correlate the immunoexpression of Trx and MT in actinic cheilitis, lip squamous cell carcinoma, and normal vermillion lip mucosa. DESIGN Immunohistochemistry was undertaken for Trx and MT in samples of actinic cheilitis, lip squamous cell carcinoma, and normal lip mucosa. Qualitative and semi-quantitative evaluations were conducted. The proportion of stained cells, intensity of staining, and the cell compartment labeled were evaluated. A quickscore index was also calculated by multiplying the values of extension and intensity of nuclear and cytoplasmic staining, respectively, giving a maximum value of 9. Statistics were performed. RESULTS A remarkable nuclear Trx staining was seen in normal lip mucosa and cheilitis, not in carcinoma (p<0.05). Cytoplasmic Trx expression was widely detected in all lesions (p>0.05). MT was broadly expressed in nuclei and cytoplasm of carcinoma, but not in normal lip mucosa and cheilitis (p<0.05). Quickscores were in accordance with the qualitative results. CONCLUSIONS The current study showed a different immunopattern of Trx and MT between normal lip mucosa, actinic cheilitis and lip squamous cell carcinoma. The cellular compartment-based analyses evidenced differences that can be related to the proteins function. Considering the relevant roles of these proteins in cellular homeostasis, they seem to have an important role in lip carcinogenesis.

Abstract
Objective: The aim of this study was to assess the importance of early diagnosis of potentially malignant lesions in the prevention of oral cancer. Material and methods: In order to achieve the set objectives, we selected our participant pool. Of the 340 patients who came to the initial examination at the Clinic for Oral Medicine and Periodontology, we selected 40 patients with potentially malignant oral lesions (PMOL) of both sexes and of different ages. After an extensive anamnesis and a clinical examination of all mucous membranes, we documented potentially malignant lesions, their localization, subjective and objective symptoms, duration of pathological lesion, and bad habits (smoking and alcohol). All lesions were colored with Toluidine blue, which indicates malignancy in 75% of cases. Patients who had a positive Toluidine blue staining test were sent to biopsy and pathohistological analysis. Results: The most common potentially malignant lesions are Lichen reticularis (25%), Lichen erosivus (20%), and Leukoplakia (15%). The most common localization of lesions is the buccal mucosa bilaterally (26%), buccal mucosa unilaterally (10%), and the lower lip (10%). The staining test with Toluidine blue was positive at 23% PMOLs. In patients with positive Toluidine staining findings, biopsy and pathohistological analysis were performed, which showed that 20% of all lesions are carcinoma (CIS, Baseocellular Carcinoma, Squamocellular Carcinoma), while 14% are mucosal epithelial dysplasia. Statistical analysis confirmed the significance of positive staining of Toluidine blue and Leukoplakia (Spearman’s coefficient = 0.427, p = 0.006, N = 40), and statistically significant positive association of Squamocellular Carcinoma and Toluidine blue staining (Spearman’s coefficient = 0.619, p = 0.000, N = 40). Conclusion: Most oral cancers are caused by potentially malignant lesions, which is why a very detailed clinical examination with the visualization of pathological lesions is very important. Toluidine blue test can be an auxiliary tool for clinical diagnosis but does not replace the pathohistological finding. Biopsy and pathohistological findings are the gold standard in the diagnosis of oral cancers, as confirmed in our research.

Abstract
BACKGROUND Differences in immune profile between actinic cheilitis (AC), a precursor of lip squamous cell carcinoma, and normal lip vermillion (NL) have not been elucidated. OBJECTIVES To compare density, distribution, and ratios of CD8+ and FoxP3+ cells between AC and NL and assess their associations with clinicopathologic variables. METHODS Samples of AC and NL obtained between 2001 and 2013 at the College of Dentistry of the University of Concepcion, Chile, were retrospectively analyzed for immunohistochemical detection of CD8+ and FoxP3+ cells. Differences between groups were tested by Mann-Whitney U and Fisher's exact tests. Independent effects of cell densities and CD8/FoxP3 ratio with AC were assessed by multiple logistic regression analysis after adjustment for potential confounding. RESULTS A total of 62 AC and 24 NL biopsies were included. Densities of CD8+ and FoxP3+ cells in AC were significantly higher than in NL. Conversely, the CD8+/FoxP3+ ratio was significantly lower in AC as compared to NL. After adjustment for sun exposure, age, gender, and smoking status, a stromal FoxP3+ cell density higher than 0.35 cells/field was significantly associated with increased odds of AC (odds ratio [OR] = 5.01, 95% confidence interval [CI]: 1.18-21.31), while a stromal CD8+/FoxP3+ ratio higher than 5.91 was associated with decreased odds of AC (OR = 0.29, 95% CI: 0.08-1.08). CONCLUSIONS AC is characterized by increased FoxP3+ cell infiltration and a reduced CD8/FoxP3 ratio as compared to NL. Therefore, increased infiltration of FoxP3+ cells relative to CD8+ cells may contribute to the transition from normal to preneoplastic stages in lip carcinogenesis.

Abstract
BACKGROUND Actinic cheilitis (AC) is a potentially malignant disorder of the lip caused by chronic exposure to ultraviolet radiation from the sun. OBJECTIVES To evaluate the clinical, demographic, morphological and therapeutic management in AC cases data associating to the histopathological grading. METHODS Demographic, clinical and management data of 161 patients with AC were analyzed. In biopsied cases, two calibrated examiners performed histopathological grading by binary system. RESULTS There was a prevalence of males (79.5%), aged 40 years or older (77.5%), light-skinned (85.7%), experiencing occupational exposure to sunlight (80.3%), with AC presenting clinically as white lesions (33.6%). Conservative treatment was adopted in 78 cases and biopsy in 83 cases (60.2% graded as low-risk AC). There were no significant associations between histopathological grading and gender (p= 0.509), age (p=0.416), ethnicity (p=0.388), occupational exposure to sunlight (p=1.000) or clinical presentation (p=0.803). CONCLUSION This study reinforces the hypothesis that demographic and clinical characteristics of AC are not related to histopathological grading. Advice on protection from sun exposure should be encouraged to avoid progression of AC and invasive therapies.

Abstract
BACKGROUND Actinic cheilitis (AC) is a chronic inflammatory lesion that in some situations can turn into squamous cell carcinoma of the lip. The molecular mechanisms involved in this process are not yet completely understood. This study aimed to investigate the expression pattern of galectins in actinic cheilitis according to the histopathological grading. METHODS Immunoexpression of galectin-1, galectin-3, galectin-7, and galectin-9 was semiquantitatively analyzed in 65 cases of actinic cheilitis graded as low risk (n = 40) or high risk (n = 25) of malignant transformation. Association between the location of the galectins in the cellular compartments and histopathological grading was analyzed. RESULTS Galectin-1 was mainly observed in the cell cytoplasm, and was elevated (score 3) in 60% of cases, regardless of the histopathological grade (P > 0.05). Galectin-3 expression was higher in high-risk group than in the low-risk group (P < 0.05), with a predominant expression in the cytoplasm and nucleus of low-risk (67.5%), and only in the cytoplasm of high-risk cases (60%) (P < 0.05). Galectin-7 expression did not show significant differences between low-risk and high-risk groups (P > 0.05). With respect to galectin-9, 89.2% of cases were positive, showing decrease in median of scores as there was an increase in histological grade (P < 0.001), with predominant expression in the nucleus and cytoplasm. CONCLUSIONS This study is the first indication of galectins involvement in the pathogenesis and morphologic progression of actinic cheilitis, particularly galectin-3 and galectin-9.

Abstract
Precancerous lesions of oral mucosa, known as potentially malignant disorders in recent years, are consists of a group of diseases, which should be diagnosed in the early stage. Oral leukoplakia, oral submucous fibrosis, and oral erythroplakia are the most common oral mucosal diseases that have a very high malignant transformation rate. Oral lichen planus is one of the potentially malignant disorders that may be seen in six different subtypes including papular, reticular, plaque-like, atrophic, erosive, and bullous type, clinically. Atrophic and erosive subtypes have the greater increased malignant transformation risk compared to another subtypes. Although there are various etiological studies, the etiology of almost all these diseases is not fully understood. Geographically, etiologic factors may vary. The most frequently reported possible factors are tobacco use, alcohol drinking, chewing of betel quid containing areca nut, and solar rays. Early diagnosis is very important and can be lifesaving, because in late stages, they may be progressed to severe dysplasia and even carcinoma in situ and/or squamous cell carcinoma. For most diseases, treatment results are not satisfactory in spite of miscellaneous therapies. While at the forefront of surgical intervention, topical and systemic treatment alternatives such as corticosteroids, calcineurin inhibitors, and retinoids are widely used.

Abstract
Objetivo: Descrever os aspectos epidemiológicos, clínicos e histopatológicos da queilite actínica. Material e método: Foi realizado um estudo retrospectivo a partir de casos com diagnóstico clínico de queilite actínica, registrados no arquivo histopatológico do Serviço de Cirurgia de Cabeça e Pescoço do Hospital Napoleão Laureano, Paraíba, relativos ao período de 2000 a 2007. Foram selecionados 44 blocos parafinados, que apresentavam condições de reavaliação histológica através da confecção de novas lâminas. Os novos cortes foram corados em Hematoxilina e Eosina, e a avaliação histopatológica foi realizada por dois examinadores independentes, sendo as alterações classificadas de acordo com OMS. Realizou-se análise estatística descritiva em programa SPSS for Windows versão 13. Resultado: Do total da amostra, 52,3% (23) dos casos foram diagnosticados em homens e 47,7% (21) em mulheres, com idade variando de 27 a 92 anos. A maioria dos indivíduos (81,9%) tinha mais de 40 anos. Em relação às características histológicas, 68,2% (30) dos casos exibiram algum grau de displasia epitelial, sendo 36,3% (16) classificados como displasia leve, 20,4% (9) como displasia moderada e 11,3% (5), displasia severa. Em 15,9% (7), ocorreu carcinoma de células escamosas. No tecido epitelial de revestimento labial, os achados histológicos mais frequentes e identificados foram presença de degeneração hidrópica (79,5%) e hipergranulose (56,8%). Infiltrado inflamatório foi observado em 88,6% dos casos e elastose solar, em 86,4%. Conclusão: Com base nos resultados da amostra estudada, podemos concluir que a maioria das lesões de queilite actínica acometeu lábio inferior de homens, com mais de 40 anos de idade. A análise histopatológica revelou displasia e atipia celular, infiltrado inflamatório e presença de elastose solar, que são características comuns em lesões de QA.
