RESUMEN
BACKGROUND: Chronic nonspecific cheilitis is a complex condition characterized by persistent lip peeling and discomfort. This case report explores the clinical progression of a patient with history of tongue squamous cell carcinoma and subsequent Tislelizumab treatment, presenting with persistent lip peeling. CASE PRESENTATION: A patient with a history of tongue squamous cell carcinoma (T2N0M0), treated with chemotherapy, surgery, and Tislelizumab, presented with six months of persistent lip peeling. Clinical examination revealed distinct features of chronic nonspecific cheilitis with infectious angular cheilitis (Oral Candidiasis). A tailored treatment plan, emphasizing oral hygiene practices and local treatments with Sodium Bicarbonate, Tacrolimus ointment, and Chlortetracycline ointment. Follow-up visits demonstrated sustained improvement, highlighting the significance of individualized approaches. CONCLUSIONS: This case underscores the importance of recognizing and managing oral manifestations in patients with a history of cancer and immunotherapy. The patient's response to treatment suggests that a multifaceted approach, combining local therapy with lifestyle modifications, can be effective in managing chronic nonspecific cheilitis associated with immunotherapy. Routine follow-up appointments, guided by personalized medicine principles, contribute to sustained patient well-being.

OBJECTIVE: The aim of the study. Improving the efficiency of diagnosis and detailing the features of the clinic of «potentially malignant¼ diseases of the oral mucosa. MATERIALS AND METHODS: Clinical and laboratory examination of 124 patients of the department of oral mucosa diseases aged 35 to 80 years, among whom there were 75 women and 49 men, with diseases such as erythroplakia - 12 patients, verrucous leukoplakia - 52 patients, erosive form of leukoplakia - 35 patients, cheilitis Manganotti - 25 patients. Histological and immunohistochemical methods of investigation were used as diagnostics. To assess the proliferative activity of epithelial cells, the determination of the Ki-67 index was used. The synthesis of keratin 15 (K15) in epithelial layers was determined as a diagnostic criterion for the severity of neoplasia. The expression of human papillomavirus type 16 (HPV 16) antigens and p16INK4a protein in epithelial cells was studied, as well as the expression of p53 protein. RESULTS: A high prevalence of p53 mutations was observed in patients with erythroplakia. In leukoplakia, the expression of the Ki-67 protein was detected in the cell nuclei in both the basal and parabasal layers of the multilayer squamous epithelium, in 77% of cases, the expression of the p16INK4a protein in the epithelial nuclei with varying degrees of dysplastic changes was noted, and a positive reaction to HPV16 was also observed in the cell nuclei and cytoplasm of epithelial cells in the basal, parabasal and spiny epithelial layers. The appearance of K15 in the cytoplasm of cells above the basal layer with abrasive precancerous cheilitis was found in 48% of cases. CONCLUSION: To diagnose early manifestations of neoplastic processes in «potentially malignant¼ diseases of the oral mucosa, it is necessary to use both classical histological and immunohistochemical methods of investigation with various markers.

OBJECTIVES: Despite phototherapy (in the form of photodynamic therapy (PDT)-mediated oxidative stress) being utilized in the management of oral potentially malignant disorders (OPMDs), the evidence of certainty remains unclear. Hence, this systematic review and meta-analysis (PROSPERO # CRD42021218748) is aimed to evaluate the clinical efficacy of PDT-induced oxidative stress in OPMDs METHODS: PubMed, Embase, Web of Science, Scopus, and Cochrane Library databases were searched without restriction of language or year of publication. In addition, gray literature was searched and a manual search was performed. Two independent reviewers screened all the studies, assessing data extraction, risk of bias and certainty of evidence. A narrative synthesis was carried out. For the meta-analysis, random effects were considered to determine the prevalence of a total and a partial remission (PR) of oral potentially malignant disorders (OPMDs). The certainty of evidence was explored using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. RESULTS: Twenty-three studies were included in the qualitative and quantitative syntheses. A total of 880 patients were included (564 males; 218 females) with an age range between 24 and 89-years-old. The results showed the prevalence of the total and partial remissions respectively for the following OPMLs: actinic cheilitis (AC): 69.9% and 2.4%; oral leukoplakia (OL): 44% and 36.9%; oral verrucous hyperplasia (OVH): 98.5%; oral erythroleukoplakia (OEL): 92.1% and 7.9%. The prevalence of no remission of OL was 18.8%. CONCLUSIONS: PDT demonstrated significant results in clinical remission of OPMDs and most of the eligible studies have shown a total or a partial remission of the included lesions, but at a low or a very low certainty of evidence. Hence, further clinical studies with robust methodology are warranted to offer further validated data. Also, further evidence is required to understand further the mechanism of PDT-induced oxidative stress.

BACKGROUND: To evaluate the presence of myofibroblasts (MFs) in the development of lip carcinogenesis, through the correlation of clinical, histomorphometric and immunohistochemical parameters, in actinic cheilitis (ACs) and lower lip squamous cell carcinomas (LLSCCs). METHODS: Samples of ACs, LLSCCs, and control group (CG) were prepared by tissue microarray (TMA) for immunohistochemical TGF-ß, α-SMA, and Ki-67 and histochemical hematoxylin and eosin, picrosirius red, and verhoeff van gieson reactions. Clinical and microscopic data were associated using the Mann-Whitney, Kruskal-Wallis/Dunn, and Spearman correlation tests (SPSS, p < 0.05). RESULTS: ACs showed higher number of α-SMA+ MFs when compared to CG (p = 0.034), and these cells were associated with the vertical expansion of solar elastosis (SE) itself (p = 0.027). Areas of SE had lower deposits of collagen (p < 0.001), immunostaining for TGF-ß (p < 0.001), and higher density of elastic fibers (p < 0.05) when compared to areas without SE. A positive correlation was observed between high-risk epithelial dysplasia (ED) and the proximity of SE to the dysplastic epithelium (p = 0.027). LLSCCs showed a higher number of α-SMA+ MFs about CG (p = 0.034), as well as a reduction in the deposition of total collagen (p = 0.009) in relation to ACs and CG. There was also a negative correlation between the amount of α-SMA+ cells and the accumulation of total collagen (p = 0.041). Collagen and elastic density loss was higher in larger tumors (p = 0.045) with nodal invasion (p = 0.047). CONCLUSIONS: Our findings show the possible role of MFs, collagen fibers, and elastosis areas in the lip carcinogenesis process.

Importance: Kindler epidermolysis bullosa is a genetic skin-blistering disease associated with recessive inherited pathogenic variants in FERMT1, which encodes kindlin-1. Severe orofacial manifestations of Kindler epidermolysis bullosa, including early oral squamous cell carcinoma, have been reported. Objective: To determine whether hypoplastic pitted amelogenesis imperfecta is a feature of Kindler epidermolysis bullosa. Design, Settings, and Participants: This longitudinal, 2-center cohort study was performed from 2003 to 2023 at the Epidermolysis Bullosa Centre, University of Freiburg, Germany, and the Special Care Dentistry Clinic, University of Chile in association with DEBRA Chile. Participants included a convenience sampling of all patients with a diagnosis of Kindler epidermolysis bullosa. Main Outcomes and Measures: The primary outcomes were the presence of hypoplastic pitted amelogenesis imperfecta, intraoral wounds, gingivitis and periodontal disease, gingival hyperplasia, vestibular obliteration, cheilitis, angular cheilitis, chronic lip wounds, microstomia, and oral squamous cell carcinoma. Results: The cohort consisted of 36 patients (15 female [42%] and 21 male [58%]; mean age at first examination, 23 years [range, 2 weeks to 70 years]) with Kindler epidermolysis bullosa. The follow-up ranged from 1 to 24 years. The enamel structure was assessed in 11 patients, all of whom presented with enamel structure abnormalities. The severity of hypoplastic pitted amelogenesis imperfecta varied from generalized to localized pitting. Additional orofacial features observed include gingivitis and periodontal disease, which was present in 90% (27 of 30 patients) of those assessed, followed by intraoral lesions (16 of 22 patients [73%]), angular cheilitis (24 of 33 patients [73%]), cheilitis (22 of 34 patients [65%]), gingival overgrowth (17 of 26 patients [65%]), microstomia (14 of 25 patients [56%]), and vestibular obliteration (8 of 16 patients [50%]). Other features included chronic lip ulcers (2 patients) and oral squamous cell carcinoma with lethal outcome (2 patients). Conclusions and Relevance: These findings suggest that hypoplastic pitted amelogenesis imperfecta is a feature of Kindler epidermolysis bullosa and underscore the extent and severity of oral manifestations in Kindler epidermolysis bullosa and the need for early and sustained dental care.

BACKGROUND: Despite studies of dermatologic manifestations in adults with inflammatory bowel disease (IBD), little is known about the prevalence of IBD-associated skin lesions and their correlation with IBD severity in children. We aimed to address these knowledge gaps in our single-center cohort of children with IBD. METHODS: Retrospective chart review of 528 children and adolescents (≤18 years old) with IBD and seen at Mayo Clinic (Rochester, MN) between 1999 and 2017 was conducted. The Chi-Square/Fischer's exact test (with p ≤ .05 to signify statistical significance) was applied to compare categorical outcomes between Crohn's disease (CD) and ulcerative colitis (UC) patients. RESULTS: In total, 425 IBD patients (64.9% CD, 53% males) and ≥1 dermatologic diagnosis were included. Presence of ≥1 cutaneous infection was recorded in 42.8% of participants. Acne was the most common non-infectious dermatologic condition (30.8%), followed by eczema (15.8%) and perianal skin tags (14.6%). Angular cheilitis (p = .024), keratosis pilaris (KP, p = .003), and perianal skin complications (i.e., skin tags, fistula, and abscesses; all p < .001) were more frequently diagnosed among children with CD, while fungal skin infections (p = .017) were more frequently diagnosed in UC patients. Severity of IBD correlated with higher prevalence of perianal fistula (p = .003), perianal abscess (p = .041), psoriasis (p < .001), and pyoderma gangrenosum (PG, p = .003). CONCLUSIONS: Both IBD-specific and IBD-nonspecific dermatologic conditions are very prevalent in childhood IBD, the most common being infectious. Children with CD are more likely to experience angular cheilitis, KP, and perianal skin findings than those with UC. Perianal disease, psoriasis, and PG are associated with more severe IBD.

Circulating tumor DNA (ctDNA) appears as a valuable liquid biopsy biomarker in the early diagnosis, treatment, and prognosis of cancer. Here, a biosensing method derived from the AC electrokinetics (ACEK) effect was constructed in this study for the simple, efficient, and rapid method of detection of ctDNA. In the proof-of-concept experiment, ctDNA from the PIK3CA E542K mutant in breast cancer was quantified by detecting a normalized capacitance change rate using a forked-finger gold electrode as the sensing electrode in combination with the ACEK effect. We compared two formats for the construction of the approach by employing varied immobilization strategies; one is to immobilize the DNA capture probe on the electrode surface by Au-S bonding, while the other immobilizes the probe on a self-assembled membrane on the electrode surface by amide bonding. Both formats demonstrated ultrafast detection speed by completing the ctDNA quantification within 1 min and a linear range of 10 fM-10 pM was observed. Meanwhile, the immobilization via the self-assembled membrane yielded improved stability, sensitivity, and specificity than its Au-S bonding counterpart. A detection limit of 1.94 fM was eventually achieved using the optimized approach. This research provides a label-free and minute-scale universal method for the detection of various malignant tumors. The ctDNA biosensors based on the ACEK effect improved according to the probe type or electrode structure and have potential applications in tumor drug efficacy prediction, drug resistance monitoring, screening of high-risk groups, differential diagnosis, monitoring of tiny residual lesions, and prognosis determination.

Ointment pseudo-cheilitis is a recently recognized distinctive type of self-induced cheilitis. Lesions consist of a variable amount of crusts adhered to the vermilion. These crusts consist of dried saliva and dead cells mixed with applied medications attached to the lip surface. Patients are typically severely anxious or depressed; the condition impacts quality of life. Ointment pseudo-cheilitis is frequently misdiagnosed as exfoliative cheilitis or cheilitis glandularis. Biopsy reports are often non-revealing because there are no established histopathological criteria for this disease, and clinicians usually do not formulate the correct diagnostic hypothesis. Here, we present the histopathological findings of four cases of ointment pseudo-cheilitis. The most consistent finding was the presence of laminated parakeratotic material detached from the epithelium in biopsies that are devoid of other significant diagnostic changes. This material at the lip surface possibly represents physiologic labial desquamation mixed with dried saliva and applied medication. With this report, we intend to alert dermatopathologists to the diagnosis of ointment pseudo-cheilitis if they receive biopsies from patients who present clinically exuberant labial lesions that show only minimal histopathological changes.

Diet and eating habits significantly affect health and quality of life. Various diets and food eliminations can lead to nutritional deficiencies and malnutrition. This article discusses the relationship between nutrition, nutritional deficiencies, and the condition of the periodontium and oral mucosa. An analysis of PubMed materials was conducted to assess the impact of nutrition on the condition of the oral mucosa and periodontium. We also considered dietary habits such as vegetarianism, the ketogenic diet, the Paleo diet, the Mediterranean diet, the Western diet, and intermittent fasting. Vitamin deficiencies, both watersoluble and fat-soluble, as well as macroand microelements, can manifest in the oral cavity, among others, as gingivitis and bleeding, recurrent aphthous stomatitis, enamel hypomineralization, cheilitis, angular cheilitis, halitosis, glossitis, lingual papillae atrophy, and stomatitis. Malnutrition does not cause periodontal disease, but it increases the risk of its occurrence and accelerates disease progression. Inadequate nutrition, combined with other predisposing factors, may contribute to an increased risk of oral cancer and the development of leukoplakia.

Introdução:as desordens orais potencialmente malignas (DOPMs) são condições que podem preceder o aparecimento do câncer em cavidade bucal. Objetivo: descrever os principais aspectos clínicos, histológicos e tratamento da leucoplasia, eritroplasia, queilite actínica e líquen plano oral. Metodologia: trata-se de uma revisão da literatura atual, em que foram consultados artigos nas bases do MEDLINE/PUBMED e Biblioteca Virtual em Saúde, publicados nos últimos 10 anos. Os descritores foram localizados usando o vocabulário controlado do MeSH, sendo eles: Leukoplakia; Erythroplakia, Actinic cheilitis, Oral lichen planus, Diagnosis, Therapeutics. Resultados: asapresentações clínicas das DOPMs são diversas. A leucoplasia é a mais comum e deve ser distinguida da leucoplasia verrucosa proliferativa que tem uma apresentação clínica generalizada e uma tendência à recorrência após a excisão; a eritroplasia, embora rara, tem maior chance de malignização. A queilite actínica acomete com frequência o lábio inferior, tem forte relação com exposição solar e pode progredir para o carcinoma escamocelular labial; o líquen plano oral tem uma variedade de apresentações clínicas, sendo a forma reticular a mais comum. O tipo erosivo, atrófico ou bolhoso é acompanhado de sintomatologia dolorosa variável. A biópsia é essencial para confirmar a suspeita clínica das DOPMs e o encaminhamento oportuno para um especialista é indicado. Conclusão: as DOPMs podem ser encontradas durante o exame bucal, possibilitando assim, o diagnóstico precoce, e o correto encaminhamento a um especialista e a intervenção adequada, podendo reduzir a taxa de progressão dessas condições para câncer.
Introduction: Oral Potentially Malignant Disorders (OPMDs) are conditions that may precede the onset of cancer in the oral cavity. Objective: To describe the main clinical features, histological aspects and treatment of leukoplakia, erythroplakia, actinic cheilitis and oral lichen planus. Methodology: this is a review of the current literature, in which articles in the databases of MEDLINE/PUBMED and the Virtual Health Library, published in the last 10 years, were consulted. The descriptors were located using the MeSH controlled vocabulary, namely: Leukoplakia; Erythroplakia, Actinic cheilitis, Oral lichen planus, Diagnosis, Therapeutics. Results:the clinical presentations of OPMDs are diverse. Leukoplakia is the most common and must be distinguished from proliferative verrucous leukoplakia which has a generalized clinical presentation and a tendency to reoccur after excision; erythroplakia, although rare, has a greater chance of becoming malignant. Actinic cheilitis frequently affects the lower lip, is strongly related to sun exposure and can progress to labial squamous cell carcinoma; oral lichen planus has a variety of clinical presentations, with the reticular form being the most common. The erosive, atrophic or bullous type is accompanied by different levels of pain. Biopsy is essential to confirm the clinical suspicion of OPMDs and timely referral to a specialist is indicated. Conclusion: OPMDs can be found during oral examination, thus enabling early diagnosis, correct referral to a specialist and appropriate intervention, which may reduce the rate of progression of these conditions to cancer.

Introduction@#Plasma cell cheilitis (PCC) is a rare, chronic inflammatory dermatitis of unknown etiology. Due to the limited number of cases reported, no guidelines have been established for its treatment. We present a case of PCC clinically similar to actinic cheilitis or mucosal lichen planus, and squamous cell carcinoma but showed response to topical tacrolimus 0.1% ointment. @*Case Report@#A 62-year-old female with extreme fondness to piping hot food presented with a solitary painful ulceration with some pustules and bleeding on the lower lip with three (3) months duration. Skin punch biopsy revealed a dense band-like infiltrate of plasma cells which is consistent with Plasma cell cheilitis. The patient was given tacrolimus 0.1% ointment and showed significant improvement after a month of treatment.@*Conclusion@#PCC is a rare condition that should still be considered in patients presenting with persistent cheilitis. Clinical and histological correlation is advised for proper management and prognostication.

There are several differential clinical diagnoses of infectious perioral lesions in childhood, the most frequent being: herpes labialis, angular cheilitis (cheilocandidiasis) and impetigo, the latter being a bacterial infection prevalent in children, with rupture of the labial and perioral region, whose diagnosis is mainly based on clinical findings and careful analysis of the anamnesis. Objective: To present two clinical cases of bullous impetigo in pediatric patients, highlighting their characteristics, comparing, and contrasting them with their main differential diagnoses. Case report. We present two cases of 10-year-old male patients (twin brothers) with a history of Pierre Robin sequence, who attended the Pediatric Dentistry clinic of the ENES, UNAM, León unit, presenting multiple ulcerative lesions, located in the perioral area, referring two weeks of evolution. Diagnosis. The clinical diagnosis of: bullous impetigo is established for both patients. Treatment plan. Strict general hygiene measures were indicated and in the affected areas, also eliminating any object that acted as a fomite, preventing the sharing of personal hygiene products, in addition, the application of mupirocin cream at 2% was shown, carrying out the monitoring of the 14 and 30 days until complete healing. Conclusions. Perioral impetigo is frequently confused with other infections present in that location with similar clinical manifestations. In some cases, it is usually treated incorrectly. Therefore, the importance of carrying out an adequate interrogation, a thorough clinical examination and performing a clinical differential analysis in this type of injury is highlighted.

Background: Actinic cheilitis is a potentially malignant lesion most commonly found in the lower lip of individuals with chronic exposure to ultraviolet radiation. The aim of this study was to develop and to test a clinical indexthat can be used to assess the severity of actinic cheilitis.Material and Methods: The clinical index of actinic cheilitis was applied to 36 patients. An incisional biopsy wasobtained to grade oral epithelial dysplasias following the World Health Organization (WHO) and binary systems,and to evaluate their association with clinical characteristics by Fishers exact test (P<0.05). The accuracy of theindex was evaluated based on sensitivity, specificity, positive and negative predictive values, and receiver operating curve.Results: The blurring between the border of the lip and the skin was significantly associated with cases withoutdysplasia/mild epithelial dysplasia (P=0.041) and with low risk of malignancy (P=0.005). Ulcers and crusts weresignificantly associated with moderate/severe epithelial dysplasia (P=0.002 and P=0.012, respectively) and highrisk of malignancy (P=0.005 and P=0.045, respectively). Erosion showed a significant association only with highrisk cases of malignancy (P=0.024). The cut-off values of the diagnostic test showing the best performance were10 for the WHO grading system and 11 for the binary system.Conclusions: The index cut-offs with the highest accuracy were considered indicators for a biopsy. Erosion, ulceration and crusts were associated with more severe oral epithelial dysplasias. (AU)

ABSTRACT Propolis is a lipophilic resin extracted from plants by bees. The purpose of this case report was to show the importance of this substance as cause of allergic contact cheilitis. A 21-year-old female patient complained of pruritic perioral eczema for 5 years. In the past months it also affected the neck. After diagnosing contact dermatitis, she was submitted to a patch test with a Latin American baseline series. The result was strongly positive for propolis (++) and weakly positive for perfume mix I (+). After the test, the patient revealed she had been using propolis drops, per oris, for 10 years. The worsening of the condition was due to increased dose, aiming "to improve immunity", during the coronavirus disease 2019 (COVID-19) pandemic. The contact allergy to propolis might be increasing due to the widespread use of natural products. Propolis is a sensitizer to be considered in patients with long-lasting cheilitis.
