ABSTRACT
The concept of metanephric adenoma has become established in recent years. Metanephric adenoma is a rare neoplasm. Macroscopically, the cut surface of the tumor displays a tan to gray or yellow color, and tumors generally form well-circumscribed masses. Histologically, tumors are composed of small epithelial cells that form small acini. Glomeruloid bodies, which are composed of lobulated papillary projections, are occasionally seen. Although there have been few studies using chromosomal analysis, two recent studies have shown partial monosomy or LOH of 2p. On the other hand, the concept of metanephric tumors has recently become broadened. These tumors include metanephric adenomas, adenofibromas and stromal tumors, and they compose a continuous histological spectrum. Therefore, further studies on various aspects are needed to identify the gene responsible for the occurrence of metanephric tumors and, furthermore, to clarify the association among the three types of metanephric tumors.
