Características Clínicas e Histológicas del Carcinoma Basocelular
Resumen
El Carcinoma Basocelular (CBC) es el tumor maligno más común en los seres humanos y afecta sobre todo a la población caucásica. Objetivos: Determinar la frecuencia de CBC y su distribución según sexo, edad, fototipo de piel y localización anatómica. Materiales y métodos. Se realizó un estudio epidemiológico descriptivo donde se incluyeron todas las biopsias con el diagnóstico de CBC durante el lapso comprendido entre Mayo 2001 y Agosto 2002 realizadas en el Laboratorio de dermopatología del Instituto de Biomedicina, Hospital Vargas. Se recolectaron datos referentes a edad, sexo, fototipo de piel, localización anatómica y subtipo histológico. Resultados. En el periodo estudiado fueron diagnosticados 203 CBC, lo cual representa un 5% del total de biopsias procesadas. 45% de los pacientes eran del sexo femenino y 55% del masculino con edades promedio de 57 y 59 años, respectivamente. El sitio de localización mas frecuente fue la región de la cabeza, especialmente la nariz. La presencia de un patrón histológico único fue encontrado en 80% de las biopsias, siendo el CBC nodular el subtipo histológico más frecuente (68%) seguido por el CBC basoescamoso (18%). Conclusión. Nuestros hallazgos son similares a aquellos reportados en la literatura mundial con respecto al sexo, localización anatómica y subtipo histológico mas frecuente.
Abstract
Basal Cell Carcinoma (BCC) is the most common malignancy in human beings and affects predominantly the Caucasian population. Objectives: to determine the frequency of BCC and its distribution according to sex, age, skin phototype and anatomic location. Materials and methods: A descriptive epidemiological study was performed which included all skin biopsies with a diagnosis of BCC received between May 2001 and May 2002. Data regarding sex, age, skin phenotype, anatomic site and histological subtype was recorded from the Department of Dermopathology of the Instituto de Biomedicina. Results: 203 cases were diagnosed within this time period which represents 5% of the total number of biopsies processed. 45% of the patients were female and 55% males with a median age of average 57 and 59 respectively. The most frequent site affected was the head, especially the nose. 80% of the cases shoed an unique histological pattern. The nodular subtype was the most frequent one (68%) followed by the basosquamous type (18%). Conclusion: Our findings regarding sex, age, location and histological subtype of BCC are similar to those reported elsewhere in the medical literature.
