ABSTRACT

La Leucoplasia Bucal (LB) es reconocida como una lesión que presenta características histopatológicas de Displasia Epitelial (DE). La proporción de DE que progresa a carcinoma Espino Celular es variada y se encuentra en un rango de 6,6 a 36 por ciento. El objetivo de este estudio fue establecer la correlación entre LB de la mucosa bucal con diagnóstico histopatológico de DE, para tal fin se revisaron un total de 11.250 historias, pudiéndose determinar que 180 de éstas correspondían a la patología a estudiar. Estos datos fueron analizados de acuerdo a su localización anatómica, sexo, edad, grupo étnico y grado de DE, 180 casos representaron LB con diferentes grados de Displasias, de las cuales 97(52,8 por ciento) eran DE leves, 67(37,2 por ciento) DE moderadas y 18(10,0 por ciento) DE severas. La localización anatómica más frecuentemente afectada fue la mucosa del reborde alveolar con 42 casos (24,1 por ciento), seguido por la mucosa del carrillo 35 casos (19,2 por ciento). La mayor prevalencia de edad fue del grupo de 50-59años (30,2 por ciento). El sexo femenino obtuvo el mayor número de casos. 102 casos (56,4 por ciento). En cuanto al grupo étnico el caucasoideo fue el más afectado con 98 casos (53,8 por ciento). Se reportó un 43 por ciento de pacientes con hábitos tabáquicos. Al correlacionar clínico-patológicamente los casos de este estudio se pudo evidenciar que el diagnóstico clínico de Leucoplasia esta más frecuentemente relacionada con el diagnóstico histopatológico de Displasia leve


Oral Leucoplakia (OL) is a term used to describe predominantly white lesions of the oral mucous which cannot be characterized as other specific lesions and which have a potential for malignant transformation. OL is recognized as a lesion with the histopathological characteristics of epithelial dysplasia. The proportion of epithelial dysplasia (ED) which progress to spin cellular carcinomas varies within a range of 6.6 percent to 36 percent. The purpose of this study was to determine the relationship between ED of the oral mucous clinically diagnosed as Leucoplakia. To that end a total of 11,250 micro histories were reviewed, representing all the samples analized from October 1968 to December 1998. It was found that 180 of these cases reflected the pathology of interest. These data were analyzed according to their anatomical location, sex, age, ethnic group, and degree of epithelial dysplasia. 180 cases represented oral Leucoplakias with differing degrees of dysplasia, of which 97 (52.8 percent) were mild ED, 67 (37. 2 percent) were moderate ED and 18 (10 percent) were severed ED. The most frequent anatomical location reported in this study was the mucous of the alveolar ridge, with 42 cases (24. 1 percent). Next came and the cheek mucous, with 35 cases (19.2 percent). The leading age group was 50 - 59 years (30.2 percent) Females had a higher predisposition with 102 cases (56.4 percent). The Caucasian ethnic group was the most frequently affected, with 98 cases (53.8 percent). 43 percent of the patients were reported to be smokers. A clinical - pathological correlation of the cases reviewed in this study shows that Leucoplakia is most often related to histopathological diagnosis of mild dysplasia
