title: Hydropic cell variant (clear cell variant) of Wilms' tumor.
abstract: We report an unusual clear cell tumor of the kidney in infancy. The presence in our patient of a discrete mass with foci of primitive nephroblastic cells indicates the neoplastic nature of the clear cells. We discuss its distinction from clear cell sarcomas and carcinomas, and we suggest that this lesion may be inadequately separated from pediatric renal carcinomas in the literature. We recommend the term hydropic cell variant as a less confusing and more accurate descriptive designation.
