RESUMO
RESUMEN El cáncer colorectal es el tercer tipo de neoplasia maligna más frecuentemente diagnosticada para ambos sexos. El adenocarcinoma es el tipo histológico que constituye el 86% de todos los casos de carcinoma colónico; sin embargo, existen otros subtipos menos frecuentes, como el carcinoma adenoescamoso, una neoplasia sumamente rara, pero con peor pronóstico y menor sobrevida. Presentamos el caso de una paciente mujer de 68 años con un tiempo de enfermedad de 2 años, caracterizado por anemia, hematoquezia y dolor abdominal. El estudio colonoscópico reveló la presencia de tumoración a nivel de colon ascendente, el cual luego de la resección quirúrgica y estudios anatomopatológicos, resultó corresponder a un carcinoma adenoescamoso primario colónico.
ABSTRACT Colorectal cancer is the third most frequently diagnosed cancer in both men and women. Adenocarcinoma is the most common pathologic subtype of colon cancer and constitutes 86% of all colon cancers. Nontheless, there are other less frequent sybtyes of colorectal carcinomas, such as adenosquamous carcinoma, an extremely rare form of colon cancer, but with worse prognosis and greater potential of metástasis. We present the case of a 68-year-old female presented with a two-month history of anemia, hematochezia and abdominal pain. The colonoscopic study presented a tumor in the ascending colon, which after surgical resection and pathological studies, turned out to be a primary colonoc adenosquamous carcinoma.
