Arch Argent Pediatr 2015;113(6):e333-e335 / e333Presentación de casos clínicos RESUMEN El adenocarcinoma colorrectal es excepcional en niños, por lo que, generalmente, se lo diagnostica en estadios avanzados, con mal pronóstico. Presentamos el caso de una niña de 5 años de edad con proctorragia recurrente de 2 meses de evolución, sin alteraciones en los análisis de laboratorio, en quien se confirmó la existencia de un adenocarcinoma colorrectal por medio de una colonoscopía. La estatificación demostró un compromiso local sin enfermedad o metástasis a distancia. La paciente se trató con resección laparoscópica y quimioterapia adyuvante, y permaneció libre de enfermedad a 21 meses de seguimiento. Palabras clave: adenocarcinoma, neoplasias colorrectales, colonoscopía, hemotoquecia.
ABSTRACTColorectal adenocarcinoma is exceptional in children, generally diagnosed in advanced stages, with worse prognosis. We report the case of a 5 year old girl with isolated hematochezia lasting two months without other findings, in whom a colorectal adenocarcinoma was confirmed by colonoscopy. Staging revealed localized disease, extending to perisigmoid fat and a few adjacent ganglia. She was treated by laparoscopic resection and adjuvant chemotherapy, being free of disease at 21 moths of follow-up.
A 59-year-old male patient with a diagnosis of systemic lupus erythematosus and pulmonary consolidation associated with mediastinal polyadenopathies and pleural effusion, with chronic and torpid evolution. Differential dignoses and clinical implications are discussed.
