ResumenLas metástasis cutáneas de los tumores del aparato digestivo son lesiones infrecuentes que aparecen en pacientes con estadíos avanzados de la enfermedad, frecuentemente ya intervenidos del tumor primario. Son lesiones que aparecen de novo, de características variables y crecimiento rápido; suelen localizarse en tronco o extremidades inferiores y se diagnostican precozmente, lo que hace fácil su extirpación y el cierre directo del defecto.Presentamos el caso de un paciente con cáncer de colon en estadío avanzado con lesión metastásica facial de 6 cm de diámetro en mejilla derecha. Esta lesión ulcerada y maloliente, precisaba curas diarias y empeoraba la calidad de vida del paciente. Se procedió a su extirpación y para cobertura realizamos un colgajo submentoniano ipsilateral con excelente resultado. Este colgajo proporciona un tejido muy parecido al del defecto, creando mínimas secuelas de la zona donante que queda oculta en el área de sombra submandibular, por lo que representa una alternativa terapéutica ideal en defectos faciales de tamaño medio.Palabras clave Colgajo submentoniano, Metástasis cutánea, Cáncer de colon. AbstractCutaneous metastasis of the digestive tract are infrequent lesions appearing in patients with advanced disease. Most of these patients have been already operated of their primary tumour. Lesions are variable in aspect, arising de novo and evolving with rapid growth. They usually lie in the trunk or lower extremities thus facilitating an early diagnosis and management with simple extirpation and direct closure.A case-report of a patient with advanced colonic cancer is here presented. At admission he presented a cutaneous matastasic lesion in the right cheek; it was a 6 cm ulcerated, bad -smelling lesion which needed daily dressings affecting patient's normal life. The lesion was removed using successfully a submental flap as coverage. The submental flap provides a very similar tissue to facial defects, leaving no donor area sequelae which is in addition well hidden, being consequently a good tool for midsize facial defects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
