ABSTRACT
Los lipomas son tumores benignos compuestos por adipocitos maduros. Si bien representan la neoplasia más común en el cuerpo humano, su aparición en la región de la cabeza y el cuello es relativamente rara. No muestra predilección por sexo y afecta a individuos en la cuarta década de vida. Clínicamente, puede observarse un aumento de volumen nodular, de consistencia blanda y superficie lisa. Su etiopatogenia aún es desconocida, aunque algunos autores han sugerido factores endócrinos, inflamatorios, hereditarios y traumáticos. El diagnóstico se realiza a través de la evaluación clínica, con la ayuda de pruebas de imagen como la tomografía computarizada y la resonancia magnética. Sin embargo, solo puede ser confirmado mediante análisis histopatológico de la lesión, considerado el examen por excelencia. El tratamiento de los lipomas y todas sus variantes consiste en la extirpación quirúrgica total, con lo cual se disminuye la posibilidad de recidivas, que es rara de por sí. El objetivo de esta publicación es informar un caso clínico de lipoma localizado en la región de la mucosa yugal, con extirpación quirúrgica completa de la lesión de manera ambulatoria (AU)
Lipomas are benign tumors composed of mature adipo- cytes. Although they represent the most common neoplasia in the human body, their occurrence in the head and neck region is relatively rare. Regardless of gender, they affect individu- als from the fourth decade of life on. Clinically, an increase of the nodular volume with softened consistency and smooth surface can be observed. Although its etiopathogenesis is still uncertain, some authors have suggested endocrinal, inflam- matory, hereditary and traumatic factors. The diagnosis is made through clinical evaluation, with the aid of imaging ex- aminations, such as computerized tomography and magnetic resonance. However, it can only be confirmed through the histopathological analysis of the lesion, which is considered the gold standard examination. The treatment of the lipomas and all their variations consists of complete surgical exci- sion, thus diminishing the possibility of recurrence, which in turn is rare. The aim of this publication is to report a clin- ical case of lipoma, located in the jugal mucosa region and treated through complete surgical removal of the lesion on an outpatient basis (AU)

Leukoplakia is a nondetachable, potentially malignant, white lesion that is commonly found in smokers of advanced age. Leukoplakia occurs more frequently in men; however, there is a higher index of dysplastic changes and malignant transformation in women. The proposed treatments for this disease range from monitoring to surgical excision. Cryosurgery has been reported as an alternative to conventional surgery. Cryosurgery destroys the tissues of a potentially malignant lesion through the application of low temperatures. This technique offers a low rate of postsurgical infection, absence of hemorrhage, and ease of application, and it is widely accepted by patients. The most commonly used cryogenic agent, liquid nitrogen, is costly and difficult to use. The objective of this article is to suggest the use of a combination of refrigerant gases (propane and butane), commonly employed in pulp sensitivity tests, for cryosurgery of potentially malignant lesions of the oral cavity and to report a case of leukoplakia treated with this approach.
