Diagnostic management of cheilitis: an approach based on a recent proposal for cheilitis classification.

Currently, there are no clear recommendations for diagnostic management of lip inflammation and cheilitis, which is evident in the varied nomenclature and subtypes found in medical literature on cheilitis. This can confound diagnostic management. We therefore recently put forth a proposal for cheilitis classification, defining three groups of cheilitis based on duration and etiology: mainly reversible cheilitis, mainly irreversible cheilitis, and cheilitis connected to other diseases. The most common forms of cheilitis are the reversible types, usually of short duration and commonly easily resolved or treated. In contrast, irreversible types of cheilitis are rare, are harder to treat, and are confirmed only after a biopsy of an inflamed lesion. To correctly diagnose and manage the different types, practitioners must consider several factors, including visible manifestations of the disease, related diseases and symptoms, personal habits, weather conditions, allergies, nutritional deficiencies, and results from tissue swabs and biopsies. In addition, multispecialty collaboration and communication involving dermatology, oral pathology, clinical immunology, otorhinolaryngology, rheumatology, and other fields can be crucial for patient outcome. We believe our classification system would be of great benefit to researchers, patients, and doctors by simplifying both nomenclature and disease recognition, thus ensuring timely and adequate treatment.

Ointment Pseudo-Cheilitis: A Disease Distinct From Factitial Cheilitis. A Series of 13 Patients From São Paulo, Brazil.

BACKGROUND: The terms exfoliative cheilitis, factitial cheilitis, and morsicatio labiorum are used to describe self-inflicted lesions of the lip. OBJECTIVE: Here we report and analyze clinical, pathological, and therapeutic data on 13 patients with a form of factitial cheilitis that we believe should be considered a separate entity. RESULTS: Eight patients were male and 5 patients were female. All patients reported pain and presented with crusts consisting of dried saliva and topical medications adherent to the surface of the lips. These patients expressed great concern with their condition, and reported several previous, ineffective treatments. Simple reassurance only was not effective; saline compresses alleviated symptoms for a few patients. Most patients were lost to follow-up. Biopsies were not performed on all patients. CONCLUSION: This particular type of cheilitis artefacta has been previously described, but some features described herein are new and allow a specific approach: patient's behavior, the "protrusion sign," and possible improvement with antidepressants. For these cases, we propose the term ointment pseudo-cheilitis because it comprises the nature of the attached material and the lack of true inflammation. Further psychiatric characterization is a logical next step in further characterizing this difficult-to-treat condition.

Angular cheilitis: A clinical and microbial study.

AIMS: The aim of the present study was to examine clinical types and microbiological flora isolated from angular chelitis. MATERIALS AND METHODS: An eroded and/or erythematous, with or without fissure formation, nonvesicular lesion radiating from the angle of the mouth was considered to be angular chelitis. A sample of the present study comprised of 40 patients having unilateral or bilateral angular chelitis and 20 healthy individuals without any lip lesions. Clinical examination was done. In both test and control groups, the sample for microbial analysis was obtained from angle of the mouth. RESULTS: Clinically, four types of angular cheilitis lesions were found, Type I, II, III, and IV. The most common type of lesion found was Type I lesion. Microorganisms isolated from the lesion were Staphylococcus aureus, Candida or Streptococci in 33 (82.5%) cases either in pure culture or mixed culture. Among these 33 patients, S. aureus was found in 25 (75.5%) cases, Candida in 16 (48.4%) cases, and Streptococci in 5 (13.5%) cases, respectively. Out of 16 cases positive for Candida, in 13 cases further isolation of Candida was possible. Candida albicans was found in 6 cases and Candida stellastodia in 7 cases. In majority of the dentulous and edentulous patients, S. aureus showed profuse growth. CONCLUSIONS: There are microorganisms associated with angular cheilitis.

Histopathologic features in actinic cheilitis by the comparison of grading dysplasia systems.

OBJECTIVE: This study aimed to determine the histopathologic findings in actinic cheilitis (AC) and lip squamous cell carcinomas (LSCC) diagnosed at Federal University of Santa Catarina in order to attempt to predict the evolution from AC to LSCC based on the comparison of two dysplasia classification systems. METHODS: Histopathologic features were evaluated according to the World Health Organization classification of dysplasia and binary system of classification. Also, in LSCC, pattern, stage of invasion, and degree of keratinization were evaluated. A total of 58 cases of AC and 70 cases of LSCC were studied, and data correlation was performed using statistical analysis. RESULTS: The presence of dyskeratosis and keratin pearls was found to be strongly associated with severe dysplasia and could represent higher proximity between the severe dysplasia in AC and LSCC. Also, changes related to the nuclei, such as hyperchromasia, nuclear pleomorphism, anisonucleosis, increase in the number and size of nucleoli, increased number of mitoses, and atypical mitoses, indicate progression in dysplasia spectrum. CONCLUSION: Knowledge of clinical and histological features of AC and LSCC leads to better understanding of factors possibly associated with malignant transformation of epithelial dysplasia.

Correlação entre aspectos clínicos e marcadores biológicos no processo de fotocarcinogênese de lábio / Relationship between clinical aspects and biological markers during lip photocarcinogenesis process

A queilite actínica (QA) é uma lesão potencialmente maligna importante para identificar indícios precoces de transformação maligna para o carcinoma epidermoide de lábio (CEL), possibilitando a implementação de um tratamento eficiente e menos invasivo, que promova um melhor prognóstico para os pacientes. Pesquisas recentes indicam que os métodos histopatológicos geralmente são falhos em traçar o risco de malignização de casos de QA, pois além de não demonstrar as alterações genéticas presentes nos queratinócitos, não foram realizados estudos de acompanhamento clínico para avaliar se o grau de displaia epitelial da QA está relacionado ao risco de malignização para CE. Assim, a presente pesquisa teve como objetivo caracterizar, a partir dos casos atendidos no Serviço de Patologia Cirúrgica da FOUSP, qual a diferença de perfil clínico-patológico de pacientes de QA com evolução para CEL, pacientes de QA sem informações e sinais presentes de malignização e pacientes apenas diagnosticados com CEL, e também visou analisar a expressão de Ki67 e pRb nesses três grupos. Para isso, os dados dos pacientes como idade, sexo, cor da pele, aspecto clínico da lesão fundamental, coloração, tamanho e tempo de duração das lesões foram resgatados de 998 casos e distribuídos nessas três categorias. Os resultados da análise clínico-epidemiológica revelaram que o único aspecto clínico estatisticamente significante para diferenciar pacientes apenas diagnosticados com CEL dos demais

grupos foi o tempo de duração das lesões. A análise do grau de displasia epitelial nos casos de QA na amostra presente revelou que todos os pacientes de QA posteriormente diagnosticados com CEL foram classificados como lesões de alto risco, e ainda exibiram em maior frequência as atipias: aumento do número de figuras de mitose, variação anormal do tamanho do núcleo, variação anormal do tamanho da célula e alteração da relação núcleo/citoplasma, figuras de mitose anormais e aumento do número e tamanho de nucléolos. Tanto a expressão da proteína Ki-67 como da proteína pRb não demonstraram significância estatística na comparação entre os grupos do estudo. Assim, a avaliação de uma ampla série de casos revelou diferença significante no tempo de duração do CEL com relação à QA. Além disso, algumas alterações morfológicas foram observadas com maior frequência em casos de QA com evolução para CEL. No entanto, outros marcadores biológicos devem ser testados em conjunto, para tentar diagnosticar alterações precoces que levem ao desenvolvimento de CEL.

Actinic cheilitis (AC) is a potentially malignant lesion important to identify early signs of malignant transformation into lip squamous cell carcinoma (LSCC), enabling the implementation of an efficient and less invasive treatment to patients. Recent researches pointed that histopatological methods often fail to trace malignization risk in AC cases, because they are unable to identify genetic damage in keratinocytes and do not exist a clinical follow-up studie to assess if the grading of epithelial dysplasia in AC is related with the malignancy risk to LSCC development. Thus, this research aims to characterize, from cases of Surgical Pathology Service of Universidade de São Paulo, the differences in clinical and pathological profile among AC patients which had evolution to LSCC, AC patients without signs and information about malignization and patients diagnosed only with LSCC. This study also analyzed the expression of Ki-67 and pRb proteins in these three groups. To conduct this study, data as age, gender, race, fundamental lesion aspect, color, size and duration time of the lesion were collected from 998 patients. The clinical-epidemiological analysis revealed that duration time of the lesion was the statistically significant clinical feature to differentiate patients diagnosed only with LSCC from other groups. The grading of epithelial dysplasia analysis showed that all AC patients with

a posterior diagnosis of LSCC were classified as high risk lesions and these cases also exhibited most frequently atypia figures as: increased number of mitotic features, abnormal variation in nuclear size, abnormal variation in cellular size, increased nuclear/cytoplasmic ratio, abnormal mitotic features and increased number and size of nucleoli. The immunohistochemical expression of both Ki-67 and pRb protein demonstrated lack of significant statistical difference among the groups. We concluded that the evaluation of a large serie of cases revealed differences in duration time of lesion in patiens only diagnoses with LSCC and some morphological criteria were most frequent in AC cases with a posterior diagnosis of LSCC. However, other biological markers must be tested together, to try to identify early steps of LSCC development.

[Potentially malignant disorders of the oral mucosa: terminology and classification]. / Affections potentiellement malignes de la muqueuse buccale: nomenclature et classification.

The last WHO expert workgroup recommended abandoning the distinction between potentially malignant lesions and conditions. The term to use is "potentially malignant disorders". Leukoplakia is the most common of these disorders, while erythroplakia is rather rare. The diagnosis is still made by excluding other documented white or red lesions. Despite progress in molecular biology, no marker allows predicting malignant transformation. These lesions are treated surgically with or without dysplasia. It is unknown if this surgery can really prevent transformation into squamous cell carcinoma. The potential malignancy of oral lichen planus is still debated. The risk of malignant transformation is lower than that of leukoplakia. No treatment may prevent this. Other potentially malignant conditions such as oral submucous fibrosis, actinic cheilitis, lupus, and immunodeficiency are rare.

Altered cytokeratin expression in actinic cheilitis.

BACKGROUND: Actinic cheilitis (AC) is a widely recognized precancerous lesion of the lip. Varying degrees of epithelial dysplasia may be present. However, no studies have correlated epithelial changes with cytokeratin expression that might reflect the disordered maturation that is probably occurring. METHODS: Thirty-four cases diagnosed as AC were classified according to dysplasia degree, and submitted to immunohistochemical staining for the detection of cytokeratins (CKs) 7, 8, 13, 14, 16 and 19. Normal mucosa adjacent to the lesions was also evaluated. RESULTS: The results obtained showed that CK10 immunostained only superficial keratinized epithelial layers in 11 cases, and also intermediate spinous layers in 18 cases. Cytokeratin 14 was expressed in all epithelial layers of 31 cases, in two cases its expression was in the basal and intermediate layers, and one case was negative. Cytokeratin 13 immunostained 26 cases and was negative in eight cases. In these eight cases, CK13 was apparently replaced by CK16. Cytokeratin 16, besides these eight cases, was also expressed in the spinous intermediate layers of a further eight cases. The remaining CKs tested were all negative. No relation between the degree of dysplasia and the CK expression was noted. CONCLUSIONS: Cytokeratin expression in AC is different from that of normal oral mucosa, and is not related to the degree of dysplasia.

Oral health status in an institutionalised elderly Jewish population.

The oral health status and treatment needs of 95 institutionalised elderly Jewish persons were determined. The mean DMFT was 23.4, with the M component increasing with age. Untreated carious lesions were identified in men and women of all ages. A relatively small percentage (10.5%) of subjects were affected by root caries. In 75% of cases of identified periodontal disease, the condition presented as bleeding or calculus. All subjects were in need of oral hygiene instruction and 64 (67.3%) required scaling and root planing. Complex treatment formed only a small percentage of the overall treatment needs. A low prevalence of temporomandibular joint problems, denture stomatitis and angular cheilitis was noted. A relatively high prevalence of untreated oral disease of low severity was observed, indicating the need for a comprehensive form of preventive and basic oral care.

Actinic cheilitis: a review of 152 cases.

OBJECTIVE: The purpose of this study was to determine whether any clinical or histopathologic variables are associated with the severity of epithelial change in lesions of actinic cheilitis. STUDY DESIGN: A total of 152 acceptable cases of actinic cheilitis were identified from 66,067 cases accessioned from February 1989 to June 1998. For each case, the clinical information supplied by the submitting practitioner at the time of the biopsy and 8 histopathologic variables were evaluated. RESULTS: The following 5 histopathologic variables were positively correlated with an increased degree of epithelial change: acanthosis, basophilic change within the connective tissue, the presence of inflammation within the connective tissue, perivascular inflammation, and thickness of the keratin layer. None of the clinical variables was associated with an increased degree of epithelial change. CONCLUSIONS: The presence of any of the aforementioned histopathologic changes should prompt a close evaluation of the lesion for the presence of either epithelial dysplasia or carcinoma.

Classification and clinical manifestations of oral yeast infections.

By tradition oral candidosis has been classified into acute pseudomembranous (thrush), acute atrophic, chronic atrophic, and chronic hyperplastic types. However, pseudomembranous candidosis is not always acute but may last for many months. Furthermore, the value of using the term atrophic to describe an erythematous area is limited. Moreover, some of the various types have been associated with other clinical entities, which appear to have a combined bacterial/mycologic etiology. A revision of the classification should be based on the use of clinical terms, and in a previous study of multifocal oral candidosis, erythematous, plaque-like, and nodular forms were identified. A revised classification of oral candidosis which considers these aspects could be as follows: acute types: pseudomembranous and erythematous; chronic types: pseudomembranous, erythematous, plaque-like, and nodular; and Candida-associated lesions: denture stomatitis, angular cheilitis, and median rhomboid glossitis.
