RESUMO
Pancreatic metastases represent 2% of pancreatic tumors. The neoplasms most frequently metastasizing to the pancreas are breast, lung, melanoma and kidney tumors. We present the cases of two patients with pancreatic metastases from renal carcinoma diagnosed 4 and 8 years after the diagnosis and surgical treatment of the primary renal tumor. In both patients, endoscopic ultrasound was useful in the detection and characterization of these pancreatic lesions and allowed fine-needle aspiration for cytological study to be performed.

Las metástasis pancreáticas representan el 2% de los tumores pancreáticos. Las neoplasias que con más frecuencia metastatizan en el páncreas son: mama, pulmón, melanoma y riñón. Presentamos los casos clínicos de 2 pacientes con metástasis pancreáticas de carcinoma renal detectadas a los 4 y 8 años del diagnóstico e intervención quirúrgica del tumor primario renal. En ambos casos la ecoendoscopia resultó ser una técnica útil en la detección y la caracterización de estas lesiones pancreáticas, y permitió la realización de una punción para el estudio citológico
