ABSTRACT
Los cordomas son tumores malignos de crecimiento lento derivados de la notocorda. Habitualmente se localizan en el clivus y se presentan en mujeres en la tercera o cuarta décadas de la vida. La resección quirúrgica es su tratamiento de elección, pudiendo asociarse en casos selectos a radioterapia. En cordomas pequeños el tratamiento de elección es el abordaje endoscópico transnasal, transesfenoidal y para las lesiones extensas se prefiere el abordaje máxilo-mandibular con glosotomía. Para la reconstrucción, al igual que en otras áreas anatómicas, las ventajas de los tejidos óseos vascularizados sobre los no vascularizados son: la rápida consolidación, la resistencia a la infección, la reacción hipertrófica originada por la carga mecánica y la tolerancia a niveles terapéuticos de radiación. Presentamos el caso de una mujer de 24 años de edad con diagnóstico de cordoma en C2-C3, a quien se le realizó corpectomía C2-C3 y exéresis marginal de la lesión, seguida de reconstrucción con colgajo libre de peroné
Chordoma neoplasms are malignant tumors with a generally slow growth. They are usually located in the clivus. The most common presentation is in young women (third and fourth decades of life). Surgical resection is the main line of treatment, occasionally radiotherapy may be needed. As for small chordomas, transnasal endoscopical resection can be performed, however, for larger tumors a maxillo-mandibular surgical approach may be needed. For reconstruction purposes, the main advantages of using vascularized tissues are: rapid consoloditation, higher infection resistance and a hypertrophic reaction secondary to the mechanical stress. We present the case of a 24 years old female patient with a C2-C3 chordom; corpectomy and marginal resection of the tumor were performed, as well as reconstruction with a free fibula flap

El aumento de volumen en la región frontal puede deberse a múltiples etiologías, dentro de las cuales deben considerarse: mucocele, tumor de Pott-Puffy, lesiones fibro-óseas, tumores de nariz y senos paranasales, lesiones intracraneales y metástasis. El objetivo del estudio fue describir el protocolo clínico empleado en los pacientes que se presentaron con aumento de volumen frontal y una propuesta de estadificación de las lesiones inflamatorias. Se realizó un estudio retrospectivo observacional. Se encontraron 7 casos con aumento de volumen en la región frontal: 4 casos secundarios a enfermedad inflamatoria (3 casos tumor de Pott-Puffy, un mucocele frontal) y 3 por neoplasia (un caso benigno y 2 malignos). Es muy importante considerar, entre los diagnósticos diferenciales de aumento de volumen en la región frontal, enfermedades inflamatorias que pueden representar una complicación grave de infecciones nasosinusales o neoplasias malignas avanzadas. Se propone un sistema de estadificación de las lesiones inflamatorias frontales (AU)
Frontal swelling can be due to multiple etiologies, including: mucocele, Pott's puffy tumor, fibro osseous lesions, benign and malignant neoplasms of the nose and paranasal sinuses, intracranial lesions, and metastasis. The objective of this study was to describe the clinical protocol used for the diagnosis of patients presented with frontal swelling and the proposal for staging of inflammatory lesions. We performed an observational retrospective analysis. We found 7 cases of patients with frontal swelling: 4 cases secondary to inflammatory pathology (3 Potts puffy tumors and one frontal mucocele), and 3 cases secondary to neoplasms (one benign and 2 malignant neoplasms). It's very important to consider the wide differential diagnosis that can present as frontal swelling, from inflammatory pathologies secondary to possible advanced infections of the paranasal sinuses to invasive malignant neoplasms. We propose a system of staging of frontal inflammatory lesions (AU)
