Abstract

Wilms tumor is the most common renal malignancy of childhood. Relapse occurs most often within 4 years of initial diagnosis, and the most common site of metastasis is the lung. We describe a 22-year-old man who presented with hemoptysis and a solitary pulmonary lesion 20 years after primary resection of Wilms tumor. Computed tomography of the chest showed an indeterminate pulmonary mass of heterogeneous attenuation with no other in-trathoracic abnormalities. Surgical resection revealed a solitary pulmonary metastasis from Wilms tumor. Further evaluation yielded no evidence of extrathoracic metastases. This case shows that late relapse in the form of a solitary pulmonary mass can occur in patients with Wilms tumor.
