ABSTRACT
Granular cell tumor is an uncommon benign tumor derived from Schwann cells. The most common location is the tongue, followed by striated muscle bundles at other sites, and the skin. About 6-8% of granular cell tumors occur in the breast. We report the sonographic findings of a case of graunlar cell tumor occurring at that site.

Orthostatic proteinuria has been recognized as a benign condition with a good prognosis and has not been associated with any underlying glomerular disease. The pathogenesis of orthostatic proteinuria is unclear. Recently, a few foreign reports suggested that the nutcracker phenomenon, which is known as a cause of asymptomatic hematuria, may also be a major cause of orthostatic proteinuria. We report a case of a 12-year-old female patient presenting only with orthostatic proteinuria, who was diagnosed as having nutcracker phenomenon by Doppler study and venography.
