espanolCaso clinico: Mujer de 52 anos diagnosticada de adenocarcinoma colorrectal, remitida a nuestro servicio por presentar tras iniciar tratamiento con Cetuximab reaccion adversa palpebral. Discusion: El Cetuximab es un anticuerpo monoclonal cuya diana es el receptor del factor de crecimiento epidermico. Ha sido incorporado recientemente al tratamiento de tumores, principalmente el cancer colorrectal metastatico y los tumores del area otorrinolaringologica. Su tolerancia es en principio mejor que la de los agentes quimioterapicos clasicos. Sin embargo, no esta exento de efectos secundarios. La toxicidad palpebral asociada a Cetuximab ha sido recientemente descrita, por lo que la patogenia no esta establecida claramente. EnglishCase report: A 52-year-old woman with advanced colorectal cancer was referred to us for treatment of Cetuximab-related ocular side-effects. Discussion: Cetuximab is a monoclonal antibody that specifically blocks epidermal growth factor receptor activity. It has recently been approved to treat some tumors such as metastatic colorectal cancer and some ORL cancers. Tolerance to it seems to be better than that to the classic chemotherapeutic agents. However it has several side-effects. Cetuximab-related eyelid toxicity has been recently described, though the pathogenesis has not yet been clearly established.
