To the Editor:A 68-year-old man presented with proteinuria of 1-year duration.A giant 22cm × 18cm fixed mass was found upon abdominal examination.Laboratory testing revealed severe proteinuria (3.0 g/24 h) and severe hypoalbuminemia 29g/L (normal range:40-55g/L).The patient complained of passing foamy urine for a period of approximately 1 year and that the symptom seemed to worsen in the 20 days before hospital admission.Inflammatory and tumor markers were normal,but contrast-enhanced computed tomography of the abdomen [Figure 1] revealed a giant cystic solid neoplasm extending from the right upper quadrant of the retroperitoneum to the pelvis.
