Radiofrequency therapy as an effective treatment for granulomatous cheilitis: A CARE case report.

INTRODUCTION: Granulomatous cheilitis is a rare disorder characterized by recurrent, idiopathic, and painless lip swelling. The diagnosis is proven by histopathological examination. The unknown aetiology and poorly understood underlying mechanism contribute to the difficulty in establishing an effective treatment. This case study proposes the effectiveness of radiofrequency therapy in the management of refractory granulomatous cheilitis. CASE SUMMARY: A 68-year-old patient presented with hypertrophy and swelling of the lower lip, and a biopsy revealed actinic cheilitis. The patient underwent lip shaving and an advancement mucosal flap, and definitive histologic examination confirmed the diagnosis of granulomatous cheilitis. No other signs of orofacial granulomatosis were observed, and the complementary aetiological study was negative for systemic disease. The lip swelling reappeared and persisted, which interfered with the quality of life. Hence, radiofrequency therapy was performed in the submucosal and subdermal layers of the lip, resulting in significant aesthetic and functional improvement and no further relapses after five years. DISCUSSION: The management of granulomatous cheilitis is challenging. The current mainstay treatment is corticotherapy or reduction cheiloplasty in severe cases. Radiofrequency has potential as a treatment option in debilitating macrocheilia, presenting worthy long-lasting functional and aesthetical results, with minimal morbidity.

Multiple noninvasive auxiliary tests-assisted photodynamic therapy in actinic cheilitis: A case report.

Actinic cheilitis (AC) is recognized as the most common precursor lesion of squamous cell carcinoma (SCC) of the lip, with a higher risk of invasiveness and metastasis. Early accurate diagnosis and appropriate therapy are essential to prevent carcinogenesis and progression of AC. Topical 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT), a non-surgical and minimally invasive modality, has been proposed as an effective treatment for oral potentially malignant diseases (OPMDs) and oral cancers. Herein, we report a 64-year-old female patient with AC on the lower lip who received 3 sessions of ALA-PDT with an interval of 1 week. Multiple noninvasive auxiliary tests including autofluorescence imaging, toluidine blue staining, and aneuploidy with DNA image cytometry (DNA-ICM) using brushing from screening through diagnosis, treatment, and follow-up. The patient successfully showed a complete response with no adverse effects and no evidence of recurrence at the 20-month follow-up. Noninvasive auxiliary tests assisted PDT is attractive and well-tolerated and may have synergistic effects against AC.

Cheilitis Glandularis: A clinicopathologic study with emphasis on etiopathogenesis.

OBJECTIVES: Cheilitis Glandularis (CG) is an uncommon entity of obscure etiology. A cases series is presented with emphasis on etiopathogenesis. MATERIALS AND METHODS: Fourteen CG cases were analyzed according to their demographic and clinicopathologic characteristics. RESULTS: The mean age of the patients with CG was 68.1 years, while a male-to-female ratio of 1.8:1 was observed. One or more potential causative factors were identified for each patient, including long-term smoking (9 cases), xerostomia (4 cases), cosmetic filler injections (2 cases), and actinic cheilitis (1 case). The lesions were located on the lips, buccal mucosa, or both in 7, 2, and 5 cases, respectively. Multiple submucosal nodules with dilated ductal orifices and mucous or purulent discharge were observed in all cases. Histopathologically, ductal ectasia with metaplasia, intraductal mucin, and chronic or mixed inflammation were noted, as well as pools of hyaluronic acid in 2 cases with a history of cosmetic filler injections. CONCLUSIONS: CG etiopathogenesis is probably multifactorial. Reduced salivary flow rate and increased viscosity of saliva, potentially caused by long-term smoking, diabetes mellitus, and drug-induced xerostomia, may participate in the initial pathogenesis, while local irritants, for example, poor oral hygiene and local trauma, may further contribute to the development and aggravation of the condition.

Cheilitis: A cross-sectional study-multiple factors involved in the aetiology and clinical features.

OBJECTIVE: Since the aetiologies of cheilitis are broad and overlapping, the purpose of this cross-sectional clinical study was to examine the multiple factors involved in aetiology and the disease's clinical features. SUBJECTS AND METHODS: We analysed cheilitis prevalence, demography, clinical features, patients' habits, psychological stress, systemic diseases, vitamin B9, B12 and iron serum levels and allergy test results in a total of 130 subjects with cheilitis, plus 22 healthy subjects. RESULTS: The most common cheilitis types were: cheilitis simplex and eczematous cheilitis (28.5%); herpetic cheilitis (16.9%); and exfoliative and angular cheilitis (7.7%). Concerning bad habits, there was a significant association/connection between self-reported saliva at the corners of the mouth and angular cheilitis, and between lip licking/biting and exfoliative cheilitis. Common associated conditions were skin diseases (56.5%) and atopy (84%). Vitamin B9 and B12 serum and iron values were mostly within the normal reference range. The patients suffering from herpetic cheilitis had significantly higher psychological/mental stress levels than the control group. CONCLUSION: To our knowledge, this is the first study of cheilitis patients that has simultaneously analysed aetiological factors, characteristics of the disease and diagnostic parameters.

Zinc Deficiency with Cheilitis: A Report of Five Cases.

Zinc deficiency has long been known as acrodermatitis enteric dermatitis (congenital zinc deficiency). On the other hand, acquired zinc deficiency has attracted attention as a familiar disease in recent years. Epidemiological studies in Japan have shown that acquired zinc deficiency is more common than expected. It is also known that serum zinc levels fall markedly with age. In this report, several cases of acquired zinc deficiency that caused cheilitis are described. In all cases, the only symptom was cheilitis, the serum zinc level was low, and all cases were relieved by zinc supplementation. Zinc deficiency is associated with a range of pathological conditions, including mucocutaneous symptoms, delayed wound healing, dysgeusia, anemia, impaired immunity, and retarded growth development disorders. However, zinc deficiency may be overlooked even in cases of cheilitis alone. Especially in intractable cases, it is important to suspect zinc deficiency as one at the differential diagnoses.

Actinic cheilitis: Proposal of a clinical index

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 Fisher’s 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)

Actinic cheilitis in rural workers: prevalence and associated factors.

OBJECTIVE: To evaluate the prevalence of actinic cheilitis in rural workers and factors associated with the development of this condition. METHODS: A cross-sectional study was conducted in a city in Northeastern Brazil. Data were collected by clinical examination and use of a questionnaire validated with 300 rural workers. The χ2 test was employed to identify possible associations between the presence of actinic cheilitis and clinical and demographic variables. Multiple logistic regression analysis was performed using forward stepwise selection. A p value of 0.05 was considered significant. RESULTS: The prevalence of actinic cheilitis was 12.0% in the sample. The highest prevalence of actinic cheilitis was observed in white males, with low educational level, and an approximately 40-year history of sun exposure. Chronic lesions were commonly found in the lower lip and were characterized by scaling, dryness, and mild edema. Skin color, sex, educational level of patients, and cumulative sun exposure (in years), were identified as predictors of development of actinic cheilitis. CONCLUSION: Our results suggest the need to implement educational health strategies aimed to orient the population about risk factors and preventive measures of the disease. Appropriate clinical management of patients with actinic cheilitis is important for prevention of lip cancer.

First isolation and identification of Cystobasidium calyptogenae from the oral samples of an elderly patient presenting with angular cheilitis.

BACKGROUND: Angular cheilitis, an infection mainly caused by Candida yeasts, is featured by the appearance of inflammatory lesions at the bilateral corners of the mouth, particularly in patients with poor oral hygiene, ill-fitting dentures and old age. The first isolation of an atypical yeast, Cystobasidium calyptogenae, from oral samples of a patient presenting with angular cheilitis is discussed in this study. CASE PRESENTATION: Angular cheilitis was diagnosed in a 60-year-old denture-wearing woman who presented with an irritation fibroma on her right lower buccal sulcus over the premolar region. Primary cultures of her oral swab and oral rinse samples grew a pure culture of an uncommon yeast strain resembling Rhodotorula sp. Sequence analysis of the yeast internal transcribed spacer (ITS) gene region and D1D2 domain showed highest similarity (99.6% and 100%, respectively) to C. calyptogenae CBS 9125 type strain. Following 2 weeks of treatment with miconazole/fusidic acid and mouthwash, the oral lesion showed improvement with less erythema. C. calyptogenae was not isolated from the patient's oral samples upon repeat sampling. CONCLUSION: This is the first report on the isolation of C. calyptogenae from human oral samples. The ability of C. calyptogenae to grow at 37 °C and the fact that it was the only yeast species isolated from the patient's oral samples suggests its pathogenic potential and possible involvement in angular cheilitis. The ubiquitous nature of the Cystobasidium yeast is believed to increase the likelihood of opportunistic infections among immunocompromised individuals. As Cystobasidium is phenotypically indistinguishable from Rhodotorula, an emerging opportunistic pathogen, surveillance using molecular identification in clinical settings is essential in providing accurate diagnosis and treatment of uncommon yeast infections.

Exfoliative cheilitis related to psychologic factors uncovered during primary immunodeficiency evaluation.

A 40-year-old previously healthy, non-atopic woman was referred for evaluation of a possible immunodeficiency disorder in the setting of an unusual erosive cheilitis and history of recurrent methicillin-resistant Staphylococcus aureus (MRSA) infection. Extensive work-up was non-diagnostic, including screening for immunologic disorders. She had failed multiple therapeutic modalities, including corticosteroid and immunosuppressive therapy. Tissue biopsy from the lip proved pivotal in demonstrating changes suggestive of factitial disease. This led to further detailed history-taking, yielding evidence of considerable psychologic distress. The patient was diagnosed with exfoliative cheilitis related to factitial disease in association with underlying untreated anxiety and psychologic trauma.

Oral Hypersensitivity Reactions.

Allergic contact hypersensitivity reactions of the oral mucosa pose a significant medical concern for some patients. Oral hypersensitivity reactions can result from a vast number of allergenic chemicals, but occur commonly from dental materials, flavorings, and preservatives. Clinical presentation is varied and often overlaps with other oral conditions, complicating their diagnosis and management. The most common clinical entities associated with oral hypersensitivity reactions are oral lichenoid reactions and allergic contact cheilitis. In addition to reviewing these conditions and their most common corresponding allergens, this article summarizes the pathogenesis of oral hypersensitivity reactions and addresses patch testing pearls.
