N2 - The cytogenetic, histologic, and electron microscopic studies of an adult patient with Wilms' tumor are presented. Wilms' tumor (nephroblastoma) is a common renal tumor of childhood but is extremely rare in people over 15 years old. The histologic analysis of the patient's tumor, including both light and electron microscopic analysis, indicated that this tumor satisfies the histologic criteria for an adult Wilms' tumor, namely, blastemic cells that are immature renal parenchymal cells, embryonic tubular structures, and a scanty stromal component consisting of loosely arranged spindle cells. The tumor showed several ultrastructural features characteristic of adult Wilms' tumor, namely, markedly elongated mitochondria, autophagic vacuoles, and intracytoplasmic filaments. Karyotypic analysis was performed on the patient's peripheral leukocytes and tumor cells. The leukocytes showed no significant increase in gaps and breaks, and the patient appears to have a normal male karyotype. Some interesting chromosomal anomalies were observed in the cultured tumor cells: at least one chromosome 13, both chromosomes 22, and the X chromosome are missing, three markers are present, and there is a possible deletion of 12p.
