Oral leukoplakia (OL) is a premalignant lesion described as “a predominant white lesion of the oral mucosa which cannot be defined as any other known lesion”. OL located on the floor of the mouth, soft palate and tongue are considered as high-risk lesions, while, in other areas, they may be considered as of low malignancy risk. A Forty five years old male patient had complaints of white lesion on left lat. Surface of tongue, along with burning sensation since 4-5 months. He was diagnosed with Leukoplakia and he had taken allopathic medicine for 4 to 5 times, but it was inversely relapsed, so he was treated with Pratisarana of Bibhitaka Churna and Rasayana Churna, Yastimadhu Ghanavati as lozenges along with Rasayana tablets orally for a period of 6 months. After 6 month therapy, white lesion became disappear and no burning sensation. Thus this patient was successfully treated with above therapy with no recurrence or any complications till date.

Background. Oral squamous cell carcinoma is the sixth most frequent malignant tumor worldwide and the third most common cancers in developing countries. Oral leukoplakia is the best-known precursor lesion of oral squamous cell carcinoma. The aim of the present study was to compare immunohistochemical expression of antiapoptotic protein survivin in normal oral mucosa, oral leukoplakia, and oral squamous cell carcinoma. Method. Total 45 specimens of formalin fixed paraffin embedded tissue blocks, 15 in each of the following: normal oral mucosa, leukoplakia, and oral squamous cell carcinoma were used for the study. Immunohistochemical reaction for survivin protein was performed for the 4 µm thick histological sections taken on positively charged slides. Results. 20% normal mucosa cases, 53.33% cases of leukoplakia, and 80% of oral squamous cell carcinoma were found out to be survivin positive. One way ANOVA test indicated statistically significant difference of survivin expression between the three different groups p<0.001. Conclusion. A high incidence of survivin protein expression in oral epithelial dysplasia and squamous cell carcinoma samples indicate that survivin protein expression may be an early event in initiation and progression of oral squamous cell carcinoma.

Introdução: Quando estamos frente às lesões potencialmente malignas, torna-se imprescindível o acompanhamento rigoroso dessas lesões, pois são lesões frequentes e com risco de transformação maligna consideravelmente relevante, a leucoplasia e a queilite actínica, são as lesões mais comuns encontradas na cavidade bucal. Objetivo: relatar um caso de lesão potencialmente maligna em mucosa labial. Relato de caso: Paciente sexo masculino compareceu à clínica de Diagnóstico VI da Universidade do Oeste de Santa Catarina, com a presença de lesão branca em lábio inferior, o mesmo já se encontrava em acompanhamento há seis anos, com diagnóstico prévio de queilite actínica sem atipia celular (duas biópsias prévias). Aposentado, trabalhava anteriormente como agricultor, ex-fumante e ex-etilista. Clinicamente observava-se lesão esbranquiçada, com aspecto verruciforme, localizada em lábio inferior, medindo 2 cm no maior diâmetro. Além disso, o lábio encontrava-se endurecido, com aspecto roliço. Duas hipóteses de diagnóstico foram levantadas: queilite actínica associada a leucoplasia e carcinoma verrucoso. O paciente foi submetido à nova biópsia incisional. No laudo constatou-se tratar de queilite actínica com displasia epitelial leve e o tratamento proposto foi o uso de protetor labial FPS30, além de acompanhamento clínico semestral. Conclusão: O acompanhamento desse caso clínico foi possível observar alteração no perfil citológico, onde nas primeiras biópsias não era possível observar atipia celular e na biópsia mais recente foi observado uma displasia epitelial leve, portanto o acompanhamento das lesões potencialmente malignas é fundamental para prevenir sua transformação maligna, e uma nova biópsia deve ser realizada sempre que for observada alteração no aspecto clínico da lesão.Descritores: Leucoplasia; Queilite; Biópsia; Lábio.ReferênciasPindborg JJ, Reichart PA, Smith CJ, Van der Waal I.

<b><i>Introduction:</i></b> Tobacco contains several genotoxic agents including N-nitrosamine which has the potential to cause significant nuclear damage. Nuclear blebbing is a form of protrusion on the nuclear membrane and could potentially be caused by tobacco-induced genotoxicity and is closely associated with malignancy. Thus, the present study aimed to assess if tobacco-associated oral potentially malignant disorders including oral submucous fibrosis (OSF) and oral leukoplakia have a higher nuclear blebbing frequency than patients with normal oral mucosa with no history of tobacco use. <b><i>Methods:</i></b> The sample consisted of patients with OSF (<i>n</i> = 30) and oral leukoplakia (<i>n</i> = 10) and normal oral mucosa (<i>n</i> = 10). Exfoliated cells collected from the study groups were smeared on a clean microscopic slide and stained by May-Grunwald-Giemsa stain. A baseline frequency of nuclear blebbing was evaluated using a bright-field microscope with a ×100 objective. The number of nuclear blebbing per 1,000 epithelial cells was recorded and expressed in percentage. ANOVA, the Mann-Whitney U test, and Spearman’s correlation were used to analyze the data. <b><i>Results:</i></b> The mean rank of distribution of nuclear blebbing showed significant difference between all 3 groups, with the highest frequency noted in leukoplakia, followed by oral submucous and normal oral mucosa. Within OSF, the frequency of nuclear blebbing significantly increased from early stage to advanced stage. In OSF, a statistically significant positive linear correlation was noted between duration (in years), frequency (per day) of tobacco use, clinical grading, and nuclear blebbing. <b><i>Discussion/Conclusions:</i></b> The frequency of nuclear blebbing was significantly higher in oral potentially malignant disorders than normal mucosa. Nuclear blebbing also exhibited a strong dose- and time-dependent correlation with tobacco usage and clinical staging in OSF. The nuclear blebbing frequency could be a noninvasive, economic tool to assess malignant risk in tobacco-induced oral potentially malignant disorders.

The aim of our study is to measure the prevalence of oral leukoplakia in a selected population group in association with variables as gender, age, smoking and alcohol intake. The mucosal lesions were diagnosed and classified according to internationally accepted criteria. Results showed that the majority of oral leukoplakia belonged to homogenous type and only o few were non-homogenous, with a prevalence of 3.32% 1.10% respectively, a difference that was statistically significant. The most frequent location of oral leukoplakia was the oral mucosa of the cheek, lower lip, tongue and floor of the oral cavity. Our conclusion was that oral leukoplakia occurred more frequently in men over the age of 45 and smoking and alcohol abuse were positive correlated factors.
