    Congenital mesoblastic nephroma is a rare renal tumor, but common in the neonatal period. It has a benign behavior and excellent prognosis in its classic variety, but in the cellular subtype, it can present local recurrence, retroperitoneal invasion, and pulmonary and cerebral metastases. Treatment is radical nephrectomy. Prognostic factors are age less than three months and complete surgical resection. 17-day-old patient born at 35 weeks due to polyhydramnios, with prenatal diagnosis of abdominal mass. Physical examination showed right flank mass and arterial hypertension (121/79 mm Hg, TAM 77mm Hg). Abdominal ultrasound with enlarged right kidney and voluminous solid formation, 4.4 x 4.3 x 4.8 cm, heterogeneous and vascularized on Doppler in the lower pole. Abdominal tomography showed a heterogeneous nodular formation of 5.0 x 4.1 x 5.1 cm in the lower pole of the right kidney. Right radical nephrectomy was performed without complications. Evolution in the last 20 months was satisfactory and free of disease.El nefroma mesoblastico congénito es un tumor renal infrecuente, pero común en el periodo neonatal. De comportamiento benigno y pronóstico excelente en su variedad clásica pero en el subtipo celular puede presentar recurrencia local, invasión retroperitoneal y metástasis pulmonares y cerebrales. El tratamiento es la nefrectomía radical. Los factores pronósticos son la edad menor a tres meses y la resección quirúrgica completa. Paciente de 17 días nacida a las 35 semanas por polihidramnios, con diagnóstico prenatal de masa abdominal. Al examen físico masa en flanco derecho e hipertensión arterial (121/79 mm Hg, TAM 77mm Hg). Ecografía abdominal con riñón derecho aumentado de tamaño y voluminosa formación sólida, de 4,4 x 4,3 x 4,8 cm, heterogénea y vascularizada al Doppler en polo inferior. Tomografía de abdomen con formación nodular heterogénea de 5,0 x 4,1 x 5,1 cm en polo inferior del riñón derecho. Se realizó nefrectomía radical derecha sin complicaciones. Evolución en los últimos 20 meses satisfactoria y libre de enfermedad
